Hello Gentlemen, my name is Scott, just found your Ruana Forum and wanted to post a few pictures of my knife. This is a very early Ruana, it has no markings and square cut slabs. The sheath is also unmarked and has the early square buckle and two prong rivets.

It was my Grandfathers hunting knife for many years. When I turned 12 and started hunting Mule Deer he gave it to me and told me he bought from a man that made it in his garage. That was 40 years ago he told me that story, it was only till about three years ago that I discovered it was a Rudy Ruana knife. I have carried this knife on many hunts.
I hope you enjoy the pictures.
