Vintage Ruko 10in. hunting tool

This vintage 10 inch. tool is a full tang (blade through) hunting tool. The handle wood is a mystery, but it has accent colors and a hole for a paracord safety wrist rope. This is an old German knife manufacturer from the early 1900's. However, this stainless steel tang was made in Taiwan before the company went to China to save money. There is a little chip at the end of the handle, and the blade shows obvious wear from sharpening and use.
