This might seem petty but it may be a learning experience for this thread as pertains to Case knives/patterns.
Case introduced their #37 Pattern Small working knife around 1970 and named it "Sod Buster" Jr. (two words) just as they had named their #38 Pattern Large "Sod Buster". It became a Copy Wright issue and Case took action against other cutlers for using the name "Sod Buster" so now all other manufactures call them Sodbuster (one Word) thereby getting around the Copy Wright infringement. BUT in a thread like this everyone, including me, uses the one word name "Sodbuster".
At any rate, your Black "Sod Buster" is a nice example. Now all you need is a large (#38 Pattern) Sod Buster to go with it. They also made a linerlock bersion of these knives that are very nice too.
Anyway, please don't be offended by my reply. I just thought it might be a tidbit of information others would like to know.
