What I wanted was a cross between a Chicago Cutlery butcher knife, Leica M6 camera and a feather.
I just haven't seen many knives that meet enough of these criteria to entice me to try them. But, after seeing a particular knife in the Atlanta Cutlery catalog for years, I finally decided to give it a try. A few days after ordering (19.95 + shipping) I got my Mercator k55 lockback knife (a.k.a. "cat knife") in the mail. I've never been so excited about a pocketknife! It meets all my criteria, and I think folks here might appreciate some details of this very old-school design.
This carbon steel knife is made in Solingen, Germany, based on a pattern in use at least as far back as WWII and issued (?) to Wermacht troops. Many of these knives were brought back to the U.S. as war trophies, so WWII-vintage examples are relatively common.
The grip is formed by folding a single sheet of steel, so it's very strong but extremely thin--perfect for a pants pocket. The lock mechanism, rivets and bail are of stainless steel
I love this knife! The only thing that would improve it is a pocket clip instead of the lanyard bail, but a small clip can easily be attached to a short lanyard to suspend the knife in the pocket. It would be a relatively simple matter to replace the bail with a clip, but I'd hate to mess with the historical design.
This is a very solidly built knife, with a strong, crisp lock. I worried that the lock would be too easy to release, given its prominence and position, but it's not a problem at all.
One hand inertia opening is possible by grasping the exposed back of the blade and snapping the handle downward (not the safest way to open a knife, of course).
