Tormek and sharpening Lexicon

[tgbto]

Hello all,

As mentioned a few times, it would be nice if newcomers and oldtimers alike could have a shared reference for many terms we use.

The idea would be to make this a sticky thread, that would be completed/amended as often as necessary.

It would include several sections, one with common abbreviations, one with the list of tormek references as compiled by Rick and others, and possibly if Wolfgang/Sebastien authorize it, a reproduction of the drawing shown during the Advanced Sharpening youtube class, with all blade shapes and terms (bevel, choil, etc.).
It also seems to me it wouldn't be complete without a link to Rich Colvin's sharpening handbook and the Tormek Youtube channel.

What do you think ? Ken, if you think this is inappropriate, feel free to delete ! If not, feel free to reply and I will try to add the to the original post.

Abbreviations

BESS	Brubacher Edge Sharpness Scale	Measures the sharpness of the blade at a given point along the blade, at a given instant.
