Kershaw Burst Flipper Assist Knife Review

Kershaw Burst Assist Knife
Kershaw Burst Assist Knife, short review of the Kershaw model 1970

The Kershaw Burst puts a powerful, fast opening blade in your hand with just a slight tug on the flipper.  The uniquely modified clip point blade excels at piercing cuts as well as slicing and chopping.  A glass filled nylon handle tops off this fantastic every day carry knife by giving you a comfortable and secure grip.

The 3″ blade opens via the SpeedSafe® assisted opening mechanism.  Once open, the flipper becomes a blade guard (quillon) that is built with a perfect curve so your forefinger snugs right up into it and the slight curvature of the handle where they meet.  The clip point blade is razor sharp right out of the box.  Made of 8Cr13MoV stainless steel, the blade keeps a good edge, has good strength, and great corrosion resistance which makes this an ideal every day carry knife.  It will cut what you need cut, will take an edge with ease, and isn’t going to complain when you put it away without pulling out the oil can and buffing cloth.

The blade has some jimping on a thumb ramp that also blends perfectly with the handle spine.  A small ferro notch about midway up the blade spine does double duty as a control point for your thumb when you want to make controlled fine cuts.  All the edges of the ferro notch are nicely chamfered so it is a smooth, comfortable spot for your thumb.  In fact, the entire spine of the blade has been slightly “broken” or chamfered so it extremely comfortable on your thumb.

The blade has a hollow grind which makes it ideal for slicing.  The edge of the blade has a secondary V-grind bevel that takes and incredibly sharp edge. The blade locks in place with a liner lock.  The liner gets a nice solid grip on the blade when it opens so the blade sits secure in the open position.  There is a small ball detent to keep the blade in the closed position when you want it to stay that way.

The glass filled nylon handle features a textured pattern that affords you a solid grip.  The spine of the handle, as mentioned previously, has jimping near the blade and it has some on the butt of the blade as well.  I’m not quite sure that this is the kind of knife you would typically hold in a reverse grip–so the jimping on the butt adds some visual appeal but probably not really useable.  The pocket clip is tip up, right/left reversible.  This means the knife is a true ambidextrous since it is flipper activated.  The pocket clip is somewhat small–but adequate for the job.

The Kershaw Burst is an amazing production knife for under $30.  It is mid sized, has good materials, and the blade takes an extra sharp edge.  The knife is going to last a long time, it doesn’t weigh too much and it can take some serious abuse–which in my book make it an ideal EDC for pocket carry.

Kershaw BlackWash Scrambler Assist Knife Quick Review

Kershaw BlackWash Scrambler
Kershaw BlackWash Scrambler

The Kershaw BlackWash Scrambler boasts all the fantastic features of the original Scrambler with an all BlackWash finish.  What is so great about the Scrambler you ask?  Fast open, flipper style, hollow ground blade, heavy duty frame lock construction as well as a sweet G10 handle scale.  This RJ Martin designed knife is the kind of knife you are going to itch to get out of your pocket, just so you can show it off.

The hollow ground 8Cr13MoV drop point blade makes slicing easy.  Along the spine, it has a large, flat ground swedge that adds some serious class to an already good looking blade.  The BlackWash finish on the blade gives your knife a comfortable, broken in look.  The kind of look everyone wants.  The coating gives an extra layer of protection for the stainless steel blade and it hides any scratches you add to the mix when you get to work.   The blade steel gives you strength as well as good edge retention.

The blade opens fast and easy with the flipper.  Just a quick pull with your forefinger and the SpeedSafe mechanism takes over.  Once open, the blade locks into place with a hefty, solid framelock.  The handle has a very generous finger groove that is made even more secure when the flipper locks into place and adds just an extra bit of blade guard for your hand.  The textured black G10 handle scale adds even more grip and another touch of class.  The remarkably strong frame lock gets nice, solid lock up.  The pocket clip is right/left reversible.

Overall this is a fantastic spring assist knife that can be picked in our store for around $42.  Check it out here and let me know what you think of yours below.

Kershaw BlackWash Thermite SpeedSafe Assist Knife — Quick Review

Kershaw BlackWash Thermite
Kershaw BlackWash Thermite SpeedSafe assist knife.

The Kershaw Thermite is now available with a BlackWash finish.  A Rick Hinderer design, the Thermite opens quick with the SpeedSafe system and boasts a 3.5″ hollow ground blade with a flat ground “spanto” tip.  The flat ground blade will give you excellent slicing capabilities.  The “spanto” tip gives you more piercing strength as well as some prying capabilities–although I never suggest using your knife blade as a pry tool.  The great thing about the BlackWash finish is that it looks great and conceals any scratches or dents you may possibly get as you use your knife.  The blade opens with either the flipper or the dual thumb studs.

The Thermite back handle scale is stainless steel, also with a BlackWash finish.  The front scale is black G10.  This gives you more secure grip.  A framelock, it uses a stabilizer bar to ensure an even more secure lock up when the blade is opened.  The pocket clip is a four position deep carry which allows for more covert carry.

Kershaw Knockout Assist Knife Review

Kershaw Knockout Assist
Kershaw Knockout Assist Knife with Olive Green Handle Scales

The Kershaw Knockout has been around for a while.  This year, Kershaw released their newest variation which includes an Olive Green anodized handle and a black DLC coated plain blade.  The new look is fantastic.

What is the Knockout?  Quite simply, it is a smooth operating assist knife that will satisfy your demands for a high quality, every day carry knife.  The anodized aluminum handle scales have an inset stainless steel plate that creates a frame lock that Kershaw has called the Sub-Frame Lock.  An ingenious design, it creates a solid framelock that will last for a very long time since the pressure of locking the blade is on the stainless steel plate instead of softer aluminum.

The Knockout uses the classic Kershaw SpeedSafe assist system.  Just push down the flipper and the blade gets going in a hurry.  It snaps out and then locks up via the sub-frame lock.  You can also use the generously sized thumb studs to open the knife–but I prefer the flipper.

My favorite part about this USA made knife is the size.  It is amazingly thin.  If you have ever held one of the old Kershaw Breakout Automatic knives–it is thin like that.  Which makes it nice for pocket carry–it doesn’t take up a bunch of real estate in your pocket.  So if you have been looking to upgrade from that Pocket Garbage™ you are currently carrying, think about picking up the new Olive Green Kershaw Knockout Assist Knife.  And let me know what you think of yours down below.


  • SpeedSafe Assisted Opening
  • Made in the USA
  • 4 Position Deep Carry Pocket Clip
  • Steel: Sandvik 14C28N stainless steel, DLC Coating
  • Handle: 6061 T6 Aluminum, Olive Green Anodized
  • Blade Length: 3 1/4-in.
  • Closed Length: 4 5/8 in.
  • Overall Length: 7 7/8 in.
  • Weight: 3.4 oz.

30 Days with the Kershaw Blur — Knife Review

Kershaw Blur Assist Knife
Kershaw Blur Assist Knife–30 Days with Knife Review

When I opened my new Kershaw Blur, I noticed several things I immediately liked about it.  This being a Ken Onion design, it is built with the knife user in mind.  This is no fancy knife that can’t be carried and used.  This is a hard charging, built to perform knife that is ready for action when you pull it out of the box.  I immediately noticed the Trac-Tec grip tape inserts in the handle.  These feel just a bit spongy when pressed with a finger tip and are extremely grippy.  In another life, I rode skateboards.  Each skateboard deck has grip tape on it.  What you are looking for in grip tape is one that will keep your feet from slipping but won’t scratch the living daylights out of your hands when you grab your board in the middle of a jump or trick.  Same deal with a knife.  And putting my hands on the Trac-Tec grip tape insert, I can tell you–there is grip tape and then there is Trac-Tec.  This stuff is amazing.  It is soft enough that it doesn’t scratch and pull at your hand.  But the texture really gives your hand a solid purchase on the handle.  The next thing I noticed was how fast the blade opens when the thumb studs are activated.  A slight start is all it needs and the blade comes blazing out and locks up nice and tight.

Day 2 

Kershaw Blur
Kershaw Blur–Trac Tec Insert

I chose to carry the 1670OLBLK.  This means it has a black tactical blade along with a dark olive green handle.  Here are some basics about the knife.  The blade is Sandvik 14C28N stainless steel with a DLC coating.  If you aren’t sure what DLC means–it means a Diamond Like Coating.  It is a fairly durable black finish is reasonably hard and scratch resistant.  It will scratch, but not easily.  The handle is 6061-T6 anodized aluminum.  In the case of my knife, it is olive drab.  But the Blur is also available with handle colors of black, red and desert sand.  The cheat sheet of specs is as follows–direct from the Kershaw Website.

  • Made in the USA
  • SpeedSafe assisted opening
  • Liner lock
  • Thumbstud
  • Reversible (tip-up/tip-down, right) pocketclip
  • Steel: Sandvik 14C28N, DLC coating
  • Handle: 6061-T6 anodized aluminum, Trac-Tec inserts
  • Blade length: 3 3/8 in. (8.6 cm)
  • Closed length: 4 1/2 in. (11.4 cm)
  • Overall length: 7 7/8 in. (20 cm)
  • Weight: 3.9 oz.

The SpeedSafe system, if you don’t know much about it, is Kershaw’s proprietary spring assist system.  It opens fast.  I have had three Kershaw knives with the SpeedSafe and have been pleased with each one.  One of the selling points for me was the fact that this is a USA made knife.  A definite plus in my estimation.


Kershaw Blur Blade
Kershaw Blur Blade–Recurve Plain Edge, Black Finish

So what I noticed quickly was how sharp the blade is on my Kershaw Blur.  I haven’t ever had a blade with this shape belly before.  If you are wondering what a blade belly is, check out my blog post from last week on Quick Knife Terms.  The belly shape makes this a great knife for slicing actions.  So with that in mind, I set to work slicing everything I could put my hands on.  From apples to cardboard to little odds and ends around the office, I sliced a bit of everything.  Here is what I quickly noticed.  When I put the blade on the item to be sliced, I would place the part of the blade that is closest to my hand right on the item.  From there, I would pull.  The slight belly would “bite” on the item as I pulled the blade towards my self.  It would bite deeply into the item and slice it just like I wanted.  So I quickly realized, what the experts say about a belly on a blade is true.  It actually assists you in slicing cuts.  And the blade on my Blur sliced like a professional.  After several days of slicing, it still is cutting with no issues.

DAY 12

Kershaw Blur Knife
Kershaw Blur Knife–Side View

The thumb ramps on the Blur are different than any thumb studs I have ever had before.  They are angled.  Oddly enough, at first I really liked this.  Then I went through about a week where I didn’t like it. Now I am back to liking it.  Here is what happened.  When you put your thumb on these studs, the angle makes for a very natural thumb placement.  The pad of your thumb gets a solid spot to rest and as you flick your thumb forward and up (the same motion you used back when you were shooting a marble as a kid) the blade snaps right open.  This is especially nice for me.  About 10 years ago I shot a 3.5″ framing nail through the joint on my thumb.  It healed ok, but I only have about 80% strength in the thumb.  Some spring assists are hard for me to operate because of this.  Not the Blur.  It is the easiest I have ever put my hands on.  Then after a couple of days, I noticed I had several scratches on the back of my hand.  I couldn’t figure out what was going on at first.  Then I realized, the edge on the thumb studs was catching the back of my hand as I put my hand into my pocket where the Blur was resting.  For about a week, I thought it was going to be a deal breaker.  I was in love with the knife, but if it was going to slice my hand up–no joy.  But after a week, I noticed I wasn’t getting cut anymore.  Upon further study, I realized two things had solved the problem.  I had begun to put my hand into my pocket at just a slightly different angle.  And, over the now, 14 days of use, the thumb studs had smoothed just slightly.  Not a ton, but just enough that they don’t snag my hand anymore.  So problem solved.

DAY 17

Kershaw Blur Knife
Kershaw Blur Knife–Pocket Clip

The pocket clip on the Blur is in a normal position on the knife.  By this I mean that it isn’t a deep carry pocket clip.  Tip down or tip up, the pocket clip can be set either way.  I use it tip down.  I like the clip.  It is a bit wider than many pocket clips.  The knife also has a lanyard hole.

DAY 23

Had a bit of box work to do at work today. While I was at it, I figured I would cut a bunch of cardboard to see if the blade would stay sharp.  The blade performs extremely well when the material being cut is supported.  I noticed this the other day when I was cutting some thin branches off trees. It cuts extremely well when slicing. It works just as well on slice cuts whether you are pushing or pulling.

DAY 30

Kershaw Blur Knife
Kershaw Blur Knife–Spine View

If you are looking for a high quality assist knife, the Kershaw Blur definitely fits the bill.  Built tough with high quality materials, the knife is certain to quickly become an EDC favorite for you.  The handle is relatively thin and very comfortable due to the Trac-Tec insert.  The liner lock is plenty strong.  The assist mechanism is blazing fast.  The the blade is fantastic.  The pocket clip goes tip up or tip down–whichever you prefer.  And the knife is available in a variety of handle colors and blade finishes.  Don’t forget to check out the newest Blur with a blackwash finish blade.  Find your favorite Kershaw Blur on our website here.  And let me know what you think of yours down below.

Best Assisted Opening Knives under $50

What are some of the best assisted opening knives?  We get that question quite a bit here at BladeOps.  So I thought I would address the question in today’s blog entry.

There are several questions that must be addressed when looking for the best assisted opening knife.  First, how much do you want to spend on your new knife.  A $20 knife is priced lower than a $200 knife for a reason.  But, it is possible, that for you, the $20 knife is the exact one that will meet all your needs.  Or to paraphrase Pedro from Napoleon Dynamite, if you get that knife, all your wildest dreams will come true.

Today, let’s look at some really great assist knives in the under $50 range.  Several brands come to mind immediately.  Smith & Wesson, Schrade, Kershaw as well as CRKT to name just a few.  Which are the best?

SWMP3BD Assist Knife
SWMP3BD Assist Knife Tan Handle, Black Tanto Blade

Smith and Wesson has a Military and Police line of assist knives that are absolutely fantastic.  Each one uses the MAGIC assist system which has been delighting knife users for several years.  About three years ago, I carried the SWMP3 for about six months.  I used it to cut everything from boxes to ABS sprinkler pipe.  I even cut sod with it once when I ended up at a neighbor’s house helping him do some yard work and didn’t have anything else on hand.  I abused the living daylights out of that little assist knife and never heard a complaint.  It has a slide safety on the front that was always dependable.  There are several different models and tons of variations available.  Check them all the SWMP Assist Knives here.  Models 1-3 are the smaller size and 4-6 are larger.  These are dependable, tough, and durable knives that you can carry with confidence.

Schrade 6 Assist Knife
Schrade 6 Assist Knife

Schrade Assist Knives also use the MAGIC system to open.  Very dependable, these knives are available in a wide variety of blade and handle styles.  If you want a knife that has a sleek, modern look you could check out the SCHA5 series.  If you prefer a beefy, military style handle and blade the SCHA6 series might be more to your liking.  I carried a SCHA3 for a couple of months last year and was impressed most by the reliability.  At the time, it was winter which meant I didn’t use it in quite the same abusive way that I used my S&W–it mostly was used for cutting boxes and opening small packages.  The 5 and 6 series are both new this year.  With the limited lifetime warranty, anodized aluminum handles and AUS 8 blade steel, the Schrade Assist knives are a great choice in the under $50 range.  They also make a couple of Out the Front Assist Knives that are probably worth looking at if you would like an OTF.

CRKT Moxie Assist Knife
CRKT Moxie Assist Knife

CRKT has been making knives since 1994–and they have made a whole bunch of really great assist knives.  Two of my favorites are the Endorser and the Moxie.  They both use the OutBurst assist system–which is incredibly fast and dependable.  The Endorser opens with a thumb stud and has a more classic look and feel to it.  The Moxie opens the same way but has an overall outdoorsy feel to it.  They both use an interesting mechanism called the FireSafe.  The way it works is the thumb stud actually has a small mechanism at the top.  When you press the thumb stud down (toward the blade) it actuates and releases the blade so you can flick it forward and the spring of the OutBurst system takes over and snaps the blade open. I’m sure there is a more technical way to describe it, but that is my layman’s effort.  The system can take a few days getting used to, but after you have used it for a while you really begin to appreciate the extra blade security the FireSafe mechanism offers.  It makes it virtually impossible to have an accidental open in your pocket.  Check out these two great CRKT assist knives here.

Kershaw Cryo 1555TI
Kershaw Cryo 1555TI, Ti-Nitride Finish

Finally you have the Kershaw Assist knives.  My absolute favorites in the Kershaw line of assist knives are the Cryo and the Cryo II.  These knives are Rick Hinderer designs built with a flipper for easy open.  A beefy framelock keeps the blade open. At an under $40 price these knives offer an amazing amount of value.  I have the original Cryo and it is absolutely a fantastic knife.  If you want smaller, go with the Cryo.  If you prefer a bit bigger, get the Cryo II.  Both models are available in a classic stainless steel finish or with a Ti-Nitride finish.  Either way, you are going to be delighted.  To see the full line of Kershaw assist knives go here, or to see the Kershaw Cryo Assist knives look here.
