Wayne1967- I'm going to be as critical as I can- don't get mad okay? Let me start by saying I've made A LOT of stuff I found out later wasn't pc and I'm still at it- I get excited about a project and rush in and make something before I think out every aspect.
So here it goes......
The "old look" that's the way my blades looked that I soaked in bleach. There is corrosion, that's true but the look isn't like the look on an old blade. On an old blade there is a shallow pitting of tiny marks whereas the bleach gives sort of a worm wood like appearance.If you have some old high carbon steel kitchen knives look at them.
The bevel at the edge- I have never seen that on an original knife, normally the main bevel goes pretty much to the edge- an exception is scalpers sharpened on one side by Indians.
File work on the spine- I think pocket knives had file work on the springs back to 1800 and maybe earlier- I don't know about fixed blades.
The Spanish choil or fighting notch- Spanish knives had them to my knowledge and Bowies maybe after 1826 "ish" or mid 1800's- when the Sheffield outfits were making them.
The five pin "H" pattern. Maybe early 1800's.
Generally you can't go wrong with 3 pins. I've had trouble trying to find when the 5 pin pattern first appeared.
Are those brass pins? I am told brass screws were used very early in Sheffield to fasten scales together, the ends were filed flush so they look like pins but in the 1830 catalogs the screws look to be of larger diameter. Some knives had a combination of pins and a screw in the middle of a five "H" pin and the screw is of larger diameter. Iron/steel pins are probably a safer bet.
And, one particular fellow who knows perhaps more than anyone else about knives keeps telling me I am looking for black and white answers in a world full of different shades of gray, in other words, anything is possible and there are no concrete rules, what I have posted is simply my impression of what I have run across.
All that said, still a good looking knife and good craftsmanship. It took talent to make it.
