Pros: None
Cons: None

I can't believe this costs less than $30!

My example needed some edge truing & a good blowout with compressed air & some fresh KPL. I also tweaked the liner lock because my detent was too soft. After these minor adjustments this is now a really sweet knife! I expect some flaws at sub $30 prices but this is a real steal. This can compete with any $100+ CIVIVI knife (after tweaking). The steel is great for this price point. A great blade shape & an excellent all rounder EDC. This is a keeper!

Pros: None
Cons: Lock Ease of Use

Better than expected

Really surprised with this knife. Doesn’t flip as well as a ZT but it is unassisted and still fires reliably. Mines got a little lock stick and the edge is atrocious but there is no blade play and the fit and finish is easily as good as the American kershaws. With better steel this would be 120 dollar knife.

Pros: Weight, Ease of Opening, Pocket Clip, Blade Sharpness
Cons: Lock Type

Almost 5 stars

Knife arrived promptly. Comfortable handle, clip holds knife securely, perfectly centered blade, arrived very sharp. Flipper action smooth but could be better. Lock up is poor. Liner lock only catches a very small sliver of the blade, and blade slips free with almost no pressure.

Pros: Ease of Opening, Handle Feel, Overall Quality
Cons: Blade Sharpness, Lock Ease of Use

What a great value for a bunch of reasons....

This is an underappreciated knife. I bought 7 of the less expensive 8Cr13Mov one for 23 bucks for holiday gifts. Because I heard there might be some sharpness issues and lock stick, I opened each clampack (the recipients won't care) and checked them all out. Pros: - I love the KVT ball bearing opening - nice a snappy! I bet with a little WD40 to clean out the pivot from any metal dust they will be even better! - The handle is really, really comfortable - The blade shape is really useful for all sorts of tasks - really good value for the price. and for 47 bucks, the D2/Micarta variant is a steal too. Cons: - There was a little lock stick. I think that will disappear with some use. - Because I bought 7 of these, I could see there was a difference in factory edge - some were wicked and others just sharp. But anyway, one will have to sharpen 8Cr soon enough so I don't think that really matters. In the end, the is a super ergonomic user.
