Welcome to the forum!
Very cool, excellently presented and informative article Mr. Lucas. Thank you for your work and for sharing it with us.
I especially enjoyed the microscopy in coordination with edge sharpness testing; “The high carbon steel and the particle metal steel tested virtually identical. The HSS tested less sharp, which was surprising after seeing the scanned images.” Just looking at how smooth the HSS edge is it would be easy to assume it was sharper. It’s interesting that the HSS seemed to sharpen to a less “toothy” edge, however considering that those images were taken @ 5000X, the “toothy” difference is by definition microscopic.
Please keep us informed if you do any more testing!
Too bad you had to end up with a bunch of stubby little tools.
