My go to OTF is an HK Tumult, believe it or not. I have this great fascination with all things mechanical and the Tumult is just that a mechanical knife. I’ve always been one who works with his hand and often times find myself touching and just messing with things. The side button on the Tumult is to me just right
. Once you activate that spring it comes out with force, but like it’s been done a thousand times. It’s also a very safe knife, if for any reason the spring is activated and if the point comes in contact with anything the blade stops. Not only is this the perfect OTF for me the price couldn’t be better.
