The two places I learned about making, using and sharpening gravers
were at Blaine Lewis's New Approach School and at a GRS's class in
Kansas. I can heartily recommend both.
Prior to the stone setting class I took at New Approach, I am
embarrassed to confess, I had never really used a graver. I learned
to grind, sharpen and use them to do stone setting. Blaine's
teaching makes it seem easy.
At GRS I took the beginning engraving class with Sam Alfano. It was
a great introductory class and I came away from it with a GraverMax,
microscope and stand, power hone and a lot of respect for the
process and those who have mastered it.
If you're primarily interested in straight engraving check out the
GRS web site http://www.grstools.com/classes.htm. Make sure you look
at the "Meet the Instructors" section as there are different styles
of engraving and one may interest you more than another. If you go
to Tucson, Sam Alfano is usually demonstrating at Rio's Catalogue in
If you want to use gravers for stone setting, check out New Approach
School http://www.newapproachschool.com. I think Blaine will be in
Tucson at Rio's Catalogue in Motion too.
The usual disclaimers apply. I am not affiliated with the above
schools, just a very satisfied student.
