A local dealer has a Buck 110 with smooth gray bone scales and nickel plated bolsters. The knife has rounded edges and is very comfortable to hold. This is the only smooth bone 110 that I have ever seen. I have seen red and brown jigged bone and stag scales on 110's in addition to the gray bone above. Is there a list showing what Buck has put on these knives? Does Mr. Levine's book address this? Any information would be much appreciated.
