0452 Sinkovich Magnacut Review
This knife is outstanding for an everyday urban EDC folder. It’s unobtrusive, has excellent ergonomics and is “civilized” enough (nothing to abrasive) to grind a hole in a pocket or cause a premature wear area in jeans (no big deal) or $100 tactical pants (a somewhat bigger deal). The blade steel is outstanding; stainless, easier to sharpen to an unusually keen edge for stainless and it retains it’s edge well under use. The mechanics are as outstanding as the ergonomics and the blade geometry is without flaw. This is a great flipper and my go to EDC knife, frequently.

My Favorite EDC Knife
This knife has become my favorite EDC / defensive carry. The action is smooth and reliable, the handle is a perfect fit for my size M-L right hand in both forward and reverse grips, and the knife is remarkably comfortable to carry considering its size. I even like the blue carbon fiber, which I had originally planned to replace with gray. I have tried other examples that had stronger detents than I like. This one is perfect.

Perfect
I enjoy this knife so much I want a second one!! Fits in the hand great. Very satisfying opening and closing. The blue carbon fiber is a nice touch and magnacut blade steel is very nice if not the best for a folding knife. I love it!!

Lightweight carry
For a 4" knife it's very lightweight for a ZT which is a good thing. It's very nice for daily carry and doesn't weigh down my pocket. I love the blue carbon scale.
