Question: is this real or fake chinese kncok off?
Document: works great better knife then any other knife i have carried. i have owned many knifes and i like this one best. opens fast and smooth. stupid sharp. love it.
very glad to own this knife. I like to use this knife for everything, camping, fishing, and cooking. good safety and quick release.
nice finish very sharp but the auto locks didn't work. Had to send it back. Got all the money back great thank you amazon.
i dont need a thirty page novel to tell you this knife is a quality knife it opens smooth nests tight and is rock solid when open. it has a razor sharp edge but the only set back is that the veff serrations do chip easly but they only chip so far then remain razor sharp so its not so much as a default  but more of a breaking in.
got this as a purse blade for my gf i carry the big brother version to it with the curved edge and i love it as well only this is that the screws are a bit easy to wiggle out and unfortunately not clip any more due to it but a good blade with a better warranty
came razor sharp, solid locking system. very good feel to it. seems very verey solid when the blade is deployed. not that difficult to close the locking system, i got it right away. love love love this knive!! !
Wonderful knife overall. Sharp blade out of the box. Good heft/weight to it makes it feel solid and well built, which it is. The auto lawks system is interesting and does take a little getting used to. Love the black straight tanto blade, which matches my ka-bar combat/fixed blade knife.
Who knows, maybe it's the user preference that turned some of the other reviewers off.The blade came nice and sharp and the Veff serrations are very nice to look at and likely function well.The knife is well worth the money. This is likely the only knife I'll ever need.
While you'll never confuse this for a Spyderco or a Benchmade, for what you pay, you get a solid, easy handling knife that will do any reasonable thing you ask it to.
What a great size for EDC blade. Blade size is under most legal limits, but still very much capable of inflicting serious damage to an individual. The &#34;flippers&#34; allow for instant deployment of blade as you pull it from your pocket, simply by dragging it on the pocket edge.if you choose not to open it upon removal, the teflon bearing washer is incredibly fast at opening the blade. it is actually faster than many spring assist blades.
Answer: no
