I have a 110 I bought in about 1975 (2 dot). I've read the handle material is laminated Dymondwood. My handles may be Dymondwood but they do not appear to be laminated. The are small checks in them like real wood that has been machined or planed. If you follow the grain from the flat side to the edge it seems to be continuous as it would be if it is one piece. It is nothing like the Dymondwood handle (scales) on my Vanguard. On that one you can see the layers of wood. Perhaps a Buck historian can shed so light on the 110s history of material used in the handles.
I tried to take a pic but it came our blurry.
