I was lucky enough to be the first to use the NMFBM, FFBM, CG ASH-1, HR, SAR5, SFNO LE, NMSFNO and SYYK myself.
Still get a little feeling of doubt just before I use a Busse for the first time but as soon as i've pushed through that I just wail away with the new blade until it has that broken in look.
I'm still miles away from Jarvisizing blades but I try to put my users through amount of use. Even have to rotate them so that I don't forget how good some are at certain tasks.
In 2 or 3 weeks and i'll be doing a big chop fest so they'll all get a workout. I'll post some pics. The aim is to chop trees/branches the same diameter as the knife overall length. Should be good fun, although the smaller blades I reckon will be hard work. Might allow myself a baton to assist with their chopping.
