Timmy,
As others pointed out, your ergo BM is a ZTBM.
Here is a little Busse history: the ZT (Zero Tolerance) series was a 3/16" thick limited production (400 each) of the NO, SH, & BM Ergo knives. There was also a ZTSJ, of which there were 100 made (~1/4" thick). The ZT series was the result of an accident of way too much 3/16" INFI being made. I think there were a couple different batches, because some were finished very nicely while others had noticeable grind marks. There were 2 variations of the ZTNO most had the same swedge as the other ergo models, but 30 had a more prominent swedge. The original ZT knives have a satin finish with tan canvas micarta (years later a handful of black coated ZT knives appeared, maybe from leftover blanks?). Read more here.
Enjoy your time with your grandparents!
