I wanted to know what it looks like taking a blade honed on a flat stone and then progressing with it to a lengthwise convex hone.
I used my Naniwa flattening plate to measure it's lengthwise convexity that I got to be
0,3mm on a distance of 250mm.
Then created the corresponding convexity in 2D.
And it looks like that only the rear of the bevel makes contact with the hone initially. There will in this case be a gap of 6 micron between the edge and hone. This means there will first be polishing of the top area of bevel and when the material being honed away all of the bevel will contact.
Probably rather fast. If this is correct it could be tested with a marker pen before hopning on convex hone. Anyone tested?
If it's an advantage I guess needs to be tested by practice.
