Guess I will chime in here..First Thanks for the great compliment Gwinneydapooh,I can only dream of matching the knives of old...
Let's see how do I put this,Mr.Levine is correct in most of his statement,but what he didn't mention was that the blades of old England were done by many masters not just one,in there factories a man would do the same exact job on a knife from the time he started till he quit,thus you had people forging the same blade for one specific knife for over 50 years then a seperate heat treater,then you had the master that did the handle and guard work that was a master jeweler most times,then the engraving was done by another master and so on.Remeber these were still factory knives but hands on with only a few foot powered or water powered machines.I love trying to reperoduce these Bowies because of the challenge of figuring out how and why theye did the things they did.But you have to think about this I am only one person trying to reproduce what many different masters had done then and I have but one lifetime to learn what all them had each of there lifetime to master.This isn't easy.As for the American made Bowies most were ruffer working models,but when they dressed on up they did a number on it.I would love to have a time machine so I could go back and see what these knives looked like when they were new and unused yet,I bet they were imaculately made.The old factory made knives were just that factory made just like our modern factory made and not to many people expect the same fit and finish from these knives as they do from us handmade makers,so you also have to take that into consideration when looking at there fit and finish compared to ours.
As to the steel,sure a properly heat treat thin blade will flex allot but the thicker blades that had full thickness spines couldn't flex any better than ours do today.There is still so much knowledge from the old master that has been lost over the years that we may never know all there tecniques and how or why they did what they did...
Heck do we say that the Old Oriental swords werent as good as todays makers,no they were legendary and not mastered copletely yet today,close but not completely,and so goes it with the Bowie knives.
So I gues what I am trying to say is that they did what was expected of fine cutlery in the 1800 and we do what is expected of cutlery today,Heck we all cannot be Warenski who in my opinion is as close to the old masters as we have in this day and time.There never has been or ever will be a perfectly made knife but we all strive to make the best we can and hold ourselves to the standard of the times.
Heck when you think about it,we still can't master wood carving like they did in the old days,also paintings can't come close now as they did back then,the same is true in all the arts,look at the old jewelery and castins from the old days and they put modern stuff to shame,what makes us think that knives would be any different.they didn't have tv or the internet or even radios to bother them back then and would start there craft at a very early age and would be masters of it at the same time we are just getting out of school and starting a trade so we can never have as much time to learn as they did..
Hope my rambling doesn't make anyone mad at me here,these are just my thoughts on the subject and if I am wrong I will gladly change my opinion to the correct way of thinking.
