I see the issue with MS and this other guy as a business issue that really has next to nothing to do with the quality of the knives. So long as the knives are good ,he makes his deliveries and stands by the warranty I don't see how these business issues have any real place on a knife forum. I am sure you can find a few of MS's ex girlfriends(a couple of mine as well) who would be willing to complain about him online.
Some people are simply unable to accept that the realities of running a business can make certain things like coming up with 16 grand instantly, impossible.
I love Sr77 shock steel in the big knives. It has pretty [censored] good edge retention
at least with the Scrapyard heat treat as anyone who has reprofiled a Sr77 knife can attest. The real brilliance of Busse knives (besides the marketing)is the heat treat that can get Sr77 hard enough to hold a decent edge and Sr101 diff tempered for toughness.
If you like the Scrapyard style but want more edge retention definitly check out a diff tempered SwampRat. The hard part is quite a bit harder than the edge on most through tempered knives.
In case anyone is curious as to which one I am getting it is neither.
I have a flat ground Steel Heart Ergo with an 8 inch blade that I like very much
and with money tight i just can't afford the SOD although I am sure I will kick myself later. I am going to get one of the Barkie Stainless pocket scalpels as a companion knife for the SH-E.
