There have been several for me. The ramifications of collecting I guess, but the one that hurts the most is a Samuel Barlow(Neepsend) that I found in an old wooden bucket for three dollars. The scales looked like second cut stag or bone, no jigging and they must have gotten wet over the years because they were warped a bit from the liners. Integral bolster/liners, iron or steel. When I first held it, it had red rust on the blade like a very fine powder. I literally wiped it of with my fingers. I couldn't believe my eyes when I saw the name Barlow with a scimitar and touch mark stamp. The blade was full,razor shape and had some lines in the steel where he must have folded it over and hammered it out again. That was BRL's opinion on it. I had asked him back in the eighties with a picture I sent him in I think Edges? The name of the column was What Izzit. If anyone out there has any old Edges from back then please look around and post up a picture of it. I traded it away for a custom, back then the value was around $250.00. Today is anyone's guess, but I like to think it was priceless. If I had it today I would have probably lend it to a knife museum. I think the dates he made knives was around 1755 to 1820's?
