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.
