I don't know. 500 lbs would be enough to make more than 9,500 laminated
plane irons, or about 15,000 chisels. (Assuming the bulk of the tool is a
soft steel.) Seems like a lot for a niche market.

about a year and a half for me (G) well I use about 90 to 100# every three
months approx.
how much is the good white steel a pound?
