Lefties take note

First, the clip cannot be swapped to the left side. There's a tab on the back of the clip that notches into a little cutout in one of the G-10 scales to prevent the clip from rotating. Unfortunately, Kershaw didn't notch the other scale to allow the clip to be mounted 180 degrees. You could dremel out a notch yourself but you'd have to take the knife apart. I've heard complaints of Kershaw using red loctite on the Tumbler. However, mine came with blue loctite and it was easy to undue the screws. The barrel screws in the handle are free spinning so you'll need two T6 bits. I don't know if every Tumbler has this clip issue. It's possible Kershaw addressed this in later batches. If you'rs is different please say so in a review. Outside of that the Tumbler is outstanding! Action is smooth. Two tone finish on the blade is a nice touch. Feels light as a feather but has excellent balance (slightly blade forward). Slicey D2 blade that cuts similar to a Bugout. You really need to have it in hand to appreciate how attractive it is. The scales do have some sharp edges but I didn't find that to be noticeable while cutting with it. There's some striations cut into the carbon fiber that look nice but will probably collect hand gunk (but would be easy to clean). Overall, this knife is a unicorn at this price. Absolute home run for Kershaw!

Almost perfect

This is a quality Kershaw knife with D2 manual blade running on bearings. The blade has lots of belly and is very slicey. The flipper works well and is very smooth. The sub-frame lock is easy to disengage. You must be careful not to put pressure on the lock with your fingers when opening. Once you get accustomed it comes naturally. The knife only weighs only 2.6 oz and rides easily in the pocket with a tip-up deep pocket clip. The G10/carbon fiber handles are a neat design and feel fairly comfortable for medium-light use. The only problem is some sharp edges on the handles. You won't really notice them unless you bear down hard on the knife or go looking for them. It is unfortunate that Kershaw did not round all the hard edges on the handles.

soooooooo close
Michael S. on Mar 16, 2020

Really like this one. I would go 4.5 if I could. Blade is super thin behind the edge. Knife is very light and carry's well in the pocket. Action is really good for a thin blade. It looks like a knife that should cost more then it does. Only negative is some pretty sharp edges all around the scales.

Its just a good knife but its not for me.

I wanted a Sinkevich knife without the ZT price. This knife is a great knife and i would carry it everyday if it didnt feel so cheap and the carbon fiber was just better. The edges are like what others have said and they are "sharp". It flips great and the subframe lock functions well and it is also very lightweight.
