All About Pocket Knives

I recently purchased at an auction two demascus fixed blades, one is a bowie marked "TAT" and the other is unmarked. Since it was an auction, I didn't get to ask any questions of the previous owner. Does anyone recognize the "TAT" makers mark? It is a large bowie, blued steel, mixture of bone and other material rings on the handle.
The other is an unmarked skinner style, has what appears to be an iron wood handle and serrations along the top of the blade near the hilt to aide in applying thumb pressure. This one also has a leather sheath, light colored mottled surface like ostrich skin but smooth. Both are high quality knives.

Looking for any information, I have attached a picture of the "TAT" knife, but I don't have one of the other knife. I can supply a picture if you think you might know its' origin.

I appreciate any feedback!

Greetings,

There is a maker in Camarillo, CA.....named Douglas D. Brack. He uses a mark of... tAt ...but I don't know if that is how your knife is marked, as it's not visible from the picture.

El Lobo, thanks for the response. The knife is marked "tat"so I'm not sure I can contribute the knife to Mr. Brack, but I will follow up to see if he is the maker.

Thanks again!
