Hi all: I am a rather new poster at this site, so please be gentle. After perusing various threads, it appears Brian is the Olsen expert, but many of you have interesting tidbits to share. As a long-time thrower (since childhood) who is re-discovering a latent passion, I have been fortunate enough to acquire a pristine (NEVER used) set of three Olsen throwers with a matching fan-style three slot leather sheath. The sheath is stamped and spotless. Clearly, the quality of these knives is far beyond my ability and I feel quite lucky to have acquired them. I have seen the occasional lone Olsen thrower with sheath, but never a set of three with matching sheath. A retired thrower with whom I trained over 40 years ago had three, but they did not appear to be part of a set and there wasn't a matching sheath. He never let me near them, much less handle them! Anyway, any information would be greatly appreciated!
