First of all, I am not a Busse expert. I have a BM Ergo that I like, and would like to keep, but it needs some help in order to function for me. The slabs are too thin, I do not like the finish, and the sheath is not too hot. I have read on this site of a fellow named Ban who can correct the probs with the knife. I would like the knife to have a satin finish with magnum slabs. I am also looking for a good Kydex shealth. What are your suggestions, and how do I contact the modifiers?
