Old dug pocket knife... Seeking any info

[Limitool]

This old knife was dug up high on a ridge top here in Middle Tennessee. The ridge overlooked the Duck River behind my home. I think the handle is bone but I could be wrong. And as you can see it have an emblem on its side. The extended blade is broken off with another blade tucked into the handle. I believe the emblem has a brand of something etched into it but even with a magnifying glass I cannot make it out.

Does anybody have ANY ideas how I could try and "clean" off the emblem to possibly ID this old knife...? Thanks for any ideas or info based on pic.

The emblem looks like a case. What are the handles made of?

As stated in first post I believe the handle is bone but not 100% sure. I'd like help in how to clean up the emblem to possibly read it. I'm just curious. It was buried about 5".
