Possum:
I continue to search through my notes on books I have read, haven't found the refference yet.
I did find one by HD Thoreau
Two men graduate from their local school. The father of one of the lads sends his son to the university to study the science of metals. Upon graduation his father presents him with a Rogers Pen Knife.
The second youth wants to make knives. He mines his own ore, smelts his steel and makes his knife.
Which one is most apt to cut his finger?

Kevin,
I was watching Maguroku forge a blade in Seki many years ago. His apprentice was explaining how critical the size of the charcoal was. He had spent years learning to cut the charcoal into the "exact" size. His scrap pile was twice the size of the "good" pile. He said, "As Maguroku works the blade, the steel draws carbon from the charcoal and the correct size was needed to maintain the correct temperature for that transformation to take place. Folding the steel is how he controlled where the different carbon amounts would be (more at the edge, less at the spine, etc).
Hey Ed, I'd like to get that DVD. email me. and "Where's my knife?"
Forge vs stock removal diffeences?
Differential heat treat - more common of smiths.
"Hamaguri" grind ( Appleseed, Moran, Slack-belt ) not as common in stock removal ( although some do it ) which can create a thinner, but still supported edge, and less friction in a "pass though" cut.
I might also add that some smiths (very few), like Ed Fowler, get heavily into particular heat cycles, which is showing to make a difference. Also not common in Stock removal.
Lot of good info in this thread, thanx for your posts.
