I've got two, same design pattern, different makers. One is a Joseph Rodgers, Sheffield steel, and it's around 30+ years old (a hand-me- down from my fathers, issued to him in '68-'69 by Australian Army. It's held it's edge well, and is very reliable. It has "Oil the joints" stamped into the handle!
The other is an Australian made pattern, nearly identical, made by Cooper Tools, this one's about 15years old. Likewise, it's a handy tool/camping folder knife. (I think of them as a tool-clip, before tool clips were really common commercially) It's a good idea to get a belt pouch, as they don't come with one, and in the pocket, they'll put holes in your denim jeans. (This makes my missus cranky, and nobody needs that!)
