All About Pocket Knives

I found this knife among other old tools in a 19th c wooden carpenter's chest. The handle looks bone. Any information would be appreciated.

It's an old LAMSON & GOODNOW, Shellburne Falls, MA. Pocketknives made 1870's-'80's by Waterville or Gardner. The handle is rosewood or ebony or cocobolo, hard to tell from a pic. It's well-worn and used but still a cool relic. J.O'.
