Question: For what purpose do you use Onglette graver

[mitch]

Sure makes you sad when they break since they can only be resharpened a few times.

don't you hate that?! you get a graver dialed in so it's cutting like a tiny magic wand and then have catastrophic point failure.

it takes an hour to recreate that complex geometry, polished to a fair-thee-well, and it just doesn't have the same feel it had before it broke.
