Hi Mark! I’ve been a diamond stter for 30 years, just read your
comment on how often you “stone” the ends oof your gravers. Two
things come to mind…1.after sharpening, are you “polishing” all
the cutting or contact surfaces? 2 Are you using hardened steel / if
so, when you tapered them on the grinder, you may have taken out the
temper. Keep the gravers cool when grinding by dipping into water
I Polish my gravers on a “ruby stone”, fine polishing emery on a
hard block, can also be used with success. The metal you’re cutting
will also have an effect on how long the graver stays shiny. When I
bead set or cut platinum, I have to polish my graver ends
constantly, to keep a bright cut. Hope this is helpful to you…"V"
