Mercator's Geman army issue Cat Lockback. 3.3" spear point blade made in Solingen Germany. The handle is black coated metal and the picture of the cat is etched in gold color. Carbon steel blade. Lockback mechanism. Made in Germany.
The original locking mechanism. It can be found mid spine or at the bottom of the handle, and it provides tight lockup that will wear well.

Cons: None
Brilliant design.
EDC, if I could only have one knife it would be my K55K. So slim you hardly know it's in your pocket and tough enough for most tasks. Five stars only because I can't give it six!

Poor Modern Replica v.2
Forgot to mention. Like someone else already pointed out, the blade is closing directly on a piece of plastic and cuts into it with the tip. Also, the C75 steel they used for the blade has hardness of 56 HRC and frankly, any heat-treated carbon steel containing .75% carbon and having below 60 HRC is a joke. Entire trade-off in carbon steel towards stainless is the hardness = better edge retention. What's the point of even using carbon steel if it's soft?

Poor Modern Replica
This knife is a poorly made replica of a classic knife. BLADE: The back of the blade spine where the locking element meets the blade is very unevenly machined, thus the blade leans to one side (on all K55's I've seen). The blade steel is C75, European equivalent of 1075 and has very uneven edge bevel, you'll need to rebuild the bevel while sharpening. If you live in very humid climate like me, the blade will give in to rust extremely easily. LOCK: Lockback with a tight, solid lockup. However, the machining is done very unevenly and despite making the blade lean, the locking bar sticks up above the handle spine, eating into the thumb resting on it. HANDLE: Folded iron sheet that stinks once the paint starts peeling, which happens fast. In short, this is my impression: Hy. Kauffmann formerly producing these knives shuts down in 1995. Later bought by Otter-Messer which decides to redesign the knife, pick new materials, cut the costs along with the standards and reenter production in 2013. Unfortunately as a replica that looks the same but doesn't work the same.
