I got this for a friend's birthday. He uses it often and claims it to hold it's edge very well and always performs greatly. I always knew CRKT would not be a wrong choice for an affordable gift.

Great CRKT classic
Anderson S. on Jan 6, 2018

Very cool & stylish EDC w/ good materials and a super-sharp edge and serrations. The LAWKS system is pretty handy also. Love this knife and all the other models in its family.

Check out these Veff sereations!
Kenneth E. on Feb 1, 2018

This is a tactical sturdy knife. It features CRKT's autolawks system which makes sure the liner lock does not slip. The Veff serrations look gnarly and cuts rope like there's no tomorrow. I really like the titanium coat on the blade it looks cool and feels high quality. The g10 is really gripy and is milled, as well as the liners, to make the knife that much lighter. Also, really cool, the thumb stud has g10 on it so that when you hit it there's no way your thumb will slide. Cool more affordable option to check out the veff serrations. Punny name: Joe King

Good for EDC
Daniel H. on Jan 6, 2018

I own the 12GD FDE variant of this knife. I use it as a smaller alternative to the much larger M16-14D. It is pretty much the perfect size for casual EDC as it isn't too "imposing", it's lightweight thanks to the G-10 handles and also fairly slim. The blade is fairly tough and sharpens well. I'm on the fence about this style of serrations. They work well, but I haven't had to attempt to sharpen them. Their geometry is broad but aggressive. I am personally a fan of CRKT's locking system, it's intuitive and secure. Also, the flipper is smooth and reliable.

Great blade, handle not so much
Sean W. on Jan 25, 2018

I love the shape of this blade and the serrations. The veff serrations cit smoother and are easier to sharpen than traditional 3-point ones. Combined with the slight forward belly it’s a very versatile cutting tool. Unfortunately the handle limits it’s pocket time for me. It’s small, square shape makes it uncomfortable for extended use. The narrow clip doesn’t grip the pocket well and allows the knife to drift around during carry.
