    The Arc-Lock

    With its ambidexterity - and all the other attributes knife enthusiasts so relentlessly seek - the Arc-Lock might just be the perfect lock.

    Tested at over 1000 lbs. of force (measured at the lock), far surpassing conventional lock strength.

    Lightning-quick, one-handed opening and closing capability.

    Spring-action securely retains blade closed, keeping fingers safely clear while unlocking.

    Self-adjusting over time and easily cleaned for long-term optimal performance.

    VG-10 Stainless Steel

    VG-10 Stainless Steel

    VG-10 is well-known high-end Japanese steel and is considered premium. It contains vanadium which is known for its toughness. The steel is specially designed for high-quality blades used in cutlery. VG-10 can be sharpened to a fine edge that is very durable. It can maintain a hardness of Rc 60 without becoming brittle.


Customer Ratings & Reviews

X-Ray Vision is rated 4.75 out of 5 by 4.
Rated 5 out of 5 by from The PERFECT every day carry knife! This is the perfect every day carry knife! I have used this knife daily for the past seven yaers. It keeps a great edge, opens and handles easily and the lock is the safest, strongest and easiest to control of any I have ever used. It's a very strong knife, comfortable in the hand and useful as a both a tool and, if necessary, can perform as an intimidating defensive weapon. My go-to knife, the best folding knife I have ever carried.

Rated 4 out of 5 by from Love the Arc-lock I use this knife as an every day tool. This knife is wonderful. I farm and own a resturant. I use this knife reguraly every day. So far the only thing I don't like is the belt clip, it is very flimsy. It is not that big of an ordeal to fix, but I have to fix it weekly.

Rated 5 out of 5 by from One TOUGH knife I bought this knife many years ago at a gun show. Of all my EDC knives, this one finds its way into my pocket more often than any. I'm not sure what the blade steel is (bought it in 2000), but gave it it's very first sharpening last month. This blade takes a BEAUTIFUL edge! For as long as I've had this blade, and all the work I've done with it (EDC tasks mostly), I find no blade play, still locks into place solid, blade travel is silky smooth. My ONLY complaint is with the clip. I've had to bend it back into shape a few times. Other than that... Outstanding Piece!
