Rob, how old is your 110? Ebony was used from the mid 60s to 1994 and it varied greatly in color and pattern. After 1994, Buck switched to laminated Obeechee wood due to the rising cost of ebony. Blade steels were:

1964-1981: 440C
1982-1992: 425M
1993-Present: 420HC

Thanks for the comments everyone. I figured that I wasn't the only one who appreciates this American cutlery icon. As stated in another thread, like Randall, these Buck knives are fun to date. I know this one is from 1977 because of the 2 dot stamp (.110.) and the three "small head" brass pins. There were four variations of the 110 in the 70s and those changes have been well documented.

Not my knives, but here is a photo of the four variations that took place. Note the number of brass pins and head size.
