Very fine depending on the grit and they also used leather covered wheels/belts with added grit for fine polishing - higher end knives and swords of the period were finished to a mirror finish.On the blade grinding- how fine a finish is possible? Would there be grinding marks? A silversmith at Colonial Williamsburg told me he hammered out teapots absolutely smooth, is it possible to forge a blade that smooth?
A good forger using flatters can do quite a fine finish, but in most cases it will need at least a bit of filing or grinding. Silver work is worked cold so there is little scale even after annealing
regarding Bernard Levine - IMO be VERY careful using him as a source, he's not as well learned as he likes to portray - the man has 1) claimed NO knives were made from files during the 18-19th century's despite existing examples and written documentation 2) he has stated that ALL files made post 1900 are of air hardening steel - fact is most (excepting the cheap case hardened files) are made of 1095 or W1/W2 both water hardening steels....
Exactly - nomenclature was played fast and loose during the period and often does not match or modern conceptions. The Ak Toothpick is a good example, most collectors today use the name to describe daggers of a sort, yet there are plenty of original single edge clip point Bowies etched with the name Arkansas Bowie (I've got pics :hatsoff: if interested)As far as Sheffield marketing, I will additionally point out how quickly they exploited the "Bowie" market. Despite current popular modern terminology, many of these "Bowies" were marked "ARKANSAS TOOTHPICK."
Also prior to the Bowie era butcher was often applied to any large knife by the admen/journalists of the day in order to make it sound fearsome - Rezin (pronounced reason BTW) Bowie described the "original" as such, yet it bears no real relationship to what style we ascribe to that name used by fur trade.....
If any one is looking for an excellent well documented book on the Bowie, with some good references to it's predecessors, I recommend the Bowie Knife Book by Norm Flayderman. It costs $75.00 new but is chock full of color pictures so is in fact a "cheap" book considering - and then there's library loan......
