Help figure this out... Hollowgrind?
So finally realized that an 8" wheel will do a nice hollow grind spine to edge on a 1" wide blade
BUT how about the other sized wheels Looking to buy a 12" or 14" and maybe a 6" or 4"
What size wheel fits what width blade to do a clean hollow grind spine to edge?
Your help is much appreciated

i use a 4" to do nice deep hollow grinds on daggers an inch wide. you could go with a 6" wheel on a 1" wide blade. i would be worried a 4" would go through the other side.
