It's a "belt carry tool". After all large fixed blades have been carried for a very, very long time.
The specs are;
17" overall. 25.5 oz.
The blade is from 1095 rod, 12" X 1. 3/4" X 1/4" thick.
The fittings are 1018 steel welded in place.
The scales are burl. The tag on these scales was missing so
I'm not sure what they are (I hate when that happens).
