Too bad about that KL 91 being ground down. Do you have a pic of the blade? Fortunately, they are pretty inexpensive to replace since the Dutch went to the Centurion models.Def
Mine is a Victorinox...no date on the blade though, just: VictorinoxSwitzerlandStainlessRostfreiAnd I'm pretty sure it's a soldier model..Alox scales, main blade, bottle opener, can opener, and reamer. The Pioneer has a saw right?
