I recently traded for a Harold Corby custom auto. Haven't been able to find out very much about Harold or this knife. The firing button and the stripe in the handle are mother of pearl.
I do know that Paragon used his name for a production model that was a decent knife which I owned some years back.
From what I found on the web, there was a run of 30 made that were numbered. Mine has no numbers. I found a couple listed for sale back in 2003 and 2006 in the $350-$450 range.
Any info will be most appreciated...thx...Al
