I am not a Scagel expert at all, but one of my very favorite pastimes in the world is enjoying a pipe full of tobacco and discussing the state of the world with my good friend Jim Lucie. Although Scagel's are not my thing, I have been privileged to handle much of his finer works and learn many little tidbits of information from the man who is beyond a doubt the final authority on the subject. Jim was his Physician, but did not apprentice under him. Jim has told me that his fascination was with the man, as Scagel was one of the most impressive and unique individuals he ever met. It was after Bills death that Jim decided to immerse himself in what many consider the mans greatest works- the knives.
One thing that I think I can safely assume from my conversations with Jim is that the rumors of old leaf springs, or other scrap steel, are highly unlikely. There is much documented evidence that Scagel went out of his way to get the best, unused, steel he could obtain. I will leave the particulars of the sources to Jim, but one can count on the knives being made from a quality high carbon steel of simple alloy makeup. He probably used scrap steel for blacksmithing projects, as I do myself, but everything I have heard about the man tells me that he cut no corners on his knives, and this is probably why they are still some of the most valued blades in the world to this day.
After looking at many of his knives, I simply do not understand why the publications always focus on the same disproportionate, and rather Spartan hunters that I personally find unattractive (no need to flame me, Jim will be sure adjust my attitude for you

). I have seen stuff that is seldom published that is very proportionate, with nice elegant flowing lines, that may almost be described as Persian-like. One simply cannot pigeon-hole Scagel.
An expert on Scagel I am not, but I wish I had the time to spend to become the worlds foremost expert on his successor, Jim Lucie. Few people have impacted my life as much as this fine gentleman. His knowledge is only surpassed by his generosity, and every member of my family considers him family.
rhrocker, I may even have some of Scagel's actual bronze out in my shop that you could use for a guard, but I would have to check if there is any left.
