So today I took it apart, sharpened the KT Tools O1 steel iron
and tested it on a scrap of hardwood.
I have also tried to explain the difference between "grinding",
"honing" and what I call "polishing to death!"
I decided to show that straight from a coarse stone or plate you
can get a razor sharp edge as long as you get two flat edges
meeting together at the desired angle at an infinitely small
This is about all I was allowed to do in the workshop today but
I hope this clears up a few questions.
Pat Meeuwissen asked what was the bed angle? The
answer it is exactly 17 degrees sir!
The wedge is 13 degrees so the throat pocket is
Another question was about sharpening. I stated
that "sharp" did not come from "polished to oblivion". So in
this test I will try to show this by ONLY grinding to "coarse"
using a DMT DiaSharp. This is the face. FLAT to the edge is
I then ground a new bevel at about 25 degrees.
Again only to a "coarse" but again - FLAT and to the very edge
and beyond, forming a wire burr which I snapped off on my palm.
