Welcome, Mick.
I've never seen any Busse Kin kits, though I think that would be fun! I searched long and hard for a decent non-stainless knife blank to put handles on to. Finally, I found the Spyderco Mule in 52100 when they were first released and I was lucky enough to get one of those before they ran out. If any of the Busse Kin companies did something like Spyderco's Mule program, that'd be great! As for now, I'm headed more towards making a few knives from bar stock simply so I can have a knife that's not stainless. Most kit knife blanks seem to be 440, which I don't really want. Oh well.
