Ronnie,
Thanks for posting this guy. Is there evidence of the keeper being "switched"? I only ask because on many double hilt knives it was a common practice to have the keeper strap as is yours. The top sharpened edge stands less of a chance for cutting the strap as does the long sharp edge.
I will note that "most" riveted JRB's I have are opposite of your photo. I was just wondering about evidence, i.e. old stitch marks etc. that showed yours being swapped. Great knife at any rate!
Best, Capt. Chris
