Joe,
Grady was the "go-to guy", including referrals from the shop, on sheaths. This what I "know" and saw and heard, first-hand on this subject.
When I first got the RKCC up & running, I got a call from Grady. He wanted to join and actually "asked me" if I would be interested in him putting an article together for the "Knife Knews". The subject would be a detailed description of his methods for restoring old leather (sheaths).
Naturally I said "yes". When the copy was done and printed I dropped off 100 copies at the shop. I was busy, at first, out front with Scott. When I went into the office, GTR had "just" finished reading the article.
His words (GTR) were..."Perfect"...That's why we refer everyone to him on all things, sheath and leather related". This included dating them for the oldies.
Perhaps this is what Larry was referring to.
...I "still" think all this subject matter deserves it's own thread.
Stay Sharp, Capt. Chris
PS: Sorry for new members and newer RMK fanatics: "Grady" we're referring to was Grady McCotter. Sadly, shortly after he wrote the article, Grady passed away. Great guy...CCS
