Those are not bad knives at all. I got a MAM as a gift. It lives in my tackle box where it gets used mostly as a bait knife. A friend likes the Old Bear knives.So, I learned of some “other” wood handled European knives, with the thin locking blades like an Opinel has; but with different locks.
So I bought them. There are other versions, sizes and shapes on Amazon.
Also got a Gerber ArmBar Drive, on sale at $25 pre-Christmas.
The left one is a MAM Operario, about $12, it has a thin metal spring steel piece in the handle to make a liner lock, aluminum ferrule; and the right one is the Antonini Old Bear medium, about $16. Better lock, basically a tab that you slide into a notch in the blade, and it has a more solid brass ferrule. It locks closed, as well. They’re really the same size, perspective makes the MAM look bigger.
Me? I am partial to the Opinel and also to the Old Hickory knives. It’s hard not to like affordable knives that have served you well for almost as many years as you have been alive. I am eagerly awaiting the new Old Hickory folder and machete.
