In brief, the CBN does not wear out, therefore never loses its shape and does
not require resetting for bevel angles (I do all at 30 degrees), and grinds very
cool (close to a Tormek) which means less danger of burning. It is possible to
use a smoother-than-usual grit on the wheel (the 180 grit is a good all
rounder), and blades can more sefely be ground to the edge as one may on a
Tormek. This speeds up honing considerably.

They are coming down in price but not cheap - somewhere around $200 for a full
metal version (which I recommend as it is a big heat sink). Look at Woodturners
Wonders website.

In short, the CBN is a game changer. Do not ignore these wheels. They are
nothing short of wonderful.
