When I was reading around the release of the SAR4 a few guys on SAR teams were of a view that the SAR4 would be better either with a proper choil or without one.....and one referred to a SAR knife that Bill Seigle had made from their design...his knife is quite similar to the Busse 3B2 pictured below with my sage RMD...



Now I like this knife a lot as it is perfectly cammo'd for the majority of my use...but using it now for a bit I really thought it would be better with a swedge like my RMD...so keeping the blade cool by dipping it in water every time it started to heat I managed to put a swedge on it....





The knife now is able to be used just like the RMD but being slightly bigger is a better "one knife" option as it does have reasonable chopping ability and for field use it works really well.
