I bought 3 of these

This knife has it all. Style, awesome blade, great feel in hand, and easy to deploy. I honestly don't understand the negative reviews. Guess they had a bad day.

Buy this knife!

As an EDC this knife is perfect at the price point. Action is excellent. Blade shape is useful and good for all kinds of tasks. D2 is good to go. I love the sub frame lock. Smooth as butter. I can’t sing this knives praises enough. One thing to fix...the G10 is kind of sharp at the 90 degree corners. I took a fine grit sandpaper to the edges and within a minute, the problem was solved. I don’t even knock off a star for that issue. That’s how great this knife is. Feels like a BETTER ZT 0460. For a quarter the price.

Amazing value and smooth action

I've had this night for a while it is moved out over time it's easy to deploy and it drops up when I release the lock. The subframe lock is easy enough to avoid pressing down with your fingers while deploying and it has overall good cutting performance.

Great pocket knife

This has been a great pocket knife. It is sharp out of the box, has a comfortable grip and has tight lockup. It looks great and is light as well. There are a couple of items to note if you are going to buy one. First, the textured CF inlays can make retrieving the knife from my pocket slower than some of my other knives. It's not hard to do, but there is just a little extra drag there. Second, the sub frame lock is just big enough that I needed to figure out where my fingers should sit when I try to flip it open. Neither of these things are a problem for me, but if I didn't catch this knife on sale and had paid list price, I would want to know about these issues.

Excellence 3” D2 Kershaw pocket knife

This is a small lightweight 3 inch D2 steel Kershaw pocket knife. A flipper with a linear block. Easy to open one hand, easy to close one hand. Came sharp out of the box. I carried this knifeeverywhere, it’s my go to knife. I’ve purchased three of these knives. The price is excellent. I highly recommend this knife if you want a small lightweight well-made pocket knife.

Beautiful design but difficult to flip open

I love the looks of Kershaw’s sub frame locking knives. I was also pleased to see a D2 blade, opposed to the assorted Chinese #Mov steels Kershaw normally uses. My beef is that the Tumbler, like the Bareknuckle design, I find it near impossible to draw this knife out of my pocket and easily flip it open. The reason is that the subframe is so large, compared to the knife frame, that my finger(s) make contact with the subframe and this pretty much makes it impossible for the blade to open. Once I adjust my grip to keep fingers from contacting the subframe, the flipping action is great with the bearing bushings. If I carry a flipper knife, I want to draw from pocket/flip open in one smooth motion. Just like my Bareknuckle, I won’t be carrying this knife, and that’s a shame.

Disappointed!

The design looks great, but the feel is dinged by the slashes in the handle overlays (why even add the CF? Just score the base G10).The reviewer from Rockford is right about deployment; if I flip it deliberately, while holding it just right, it *almost* always opens - not good enough for a Sinkevich design that's supposed to be intimidating. I tried to disassemble the knife to check on the action, but the Torx socket in the pivot stripped, so that won't be happening, ever. Just too many little let-downs with this knife.
