  • So far, there's a problem which is exhibited with each of the razors I've used when using the coarse bevel setting grits: Burrs like you'd never dream of. Call is massive macro-chipping, etc. It's bad.
    • The substrates that caused this issue and were the worst offenders in decending order were: glass, corian, MDF type paddles then balsa. I think the hard surfaces with no give and no significant imbedding friendly properties cause the abrasive to just shred the edges. I'll try to get some pictures on my stereo mic to show what I'm talking about.

I think (from a purely theorethical point of view) that the surprisingly great ocurrence of burrs is due to the fact that the abrasive particles are totally loose (just like a coticule stone cuts a lot more if you hub it with another stone to loose it's garnets) maybe using the coarser grits in leather would embed the diamonds on the honing surface, resulting in less aggressive cuting.

Waiting for my pastes to arrive from hong kong to try this theory.
