I do about the same supertac. I think of it as paying to play. Buy it, use it, sell it.....unless it makes the grade of 'keeper' ha. Usually a guy can recoup most of his funds on the quality blades, even with use on them.
Other than S!K, I mostly I stay with Busse-kin and Nathan Carothers, which is apparent from my sig line. But I like some of Buck's production knives, the vanguard in particular, and of course the 110. I picked up a modified 110 from Silver Knights with a drop point blade in 154 CM that I really like.
I still really want a CG FBM from Busse and a choilless boss jack. Both of those really call to me. I should just break down and buy an 1111 and a 1311 from the Yard. I've got most of the Rats I want unless Jerry cranks out a Ratweiler or Rat Mastiff LE in INFI or the custom shop opens back up. If they ever do, I want one more RMD with a drop point and satin finish, hand-smoothed scales and solid pins.
