I was given one of these yesterday by a friend on another forum and thought you might like to see it. 'It' is a 1950s Harness Jack slipjoint from the Robert Klaas works in Solingen.
The Harness Jack pattern is a main blade & an awl, both at the same end of the handle. This 'un has the biggest awl I've seen on a folder. It looks like it's actually half a pair of scissors. Check out this bad boy;
Main blade is a Wharncliffe, flat ground with a (too) small secondary bevel. Steel is either 1095 or 1075 by all accounts, and the tip is made deliberately blunt, even for a wharnie;
Only mark on it is the Kissing Cranes motif, above the word Germany;
With the British Blades standard unit of measurement
;
Fit and finish aren't perfect, but this is a fifty year-old hand-made knife. That's character, that is. The backspring is incredibly strong, making the knife quite difficult to open, at least for girly-fingered ponces like me. There is a very secure half-stop on both blades.
I really like this knife. It's gone straight into EDC, replacing the Pioneer - heady praise indeed
