I don't sharpen chisels, but ran across this video yesterday. (I enjoy watching Jeff Farris at work)...

Apologies if this has been posted before, just found it fun and educational to watch. :)
And I have wondered how the heck did he sharpen that so quick. I've never been able to grind off that much metal they way he did, especially using the SG wheel.

CB,
Never apologize for sharing a Jeff Farris link on this forum. I have always considered Jeff to be one of the leading Tormek experts on the planet, certainly the expert in North America. When Jeff and Tormek went separate ways we lost a lot of expertise. Fortunately we have his forum posts and videos.
With all due respect to Jeff, he was also a bit of a showman. I have watched numerous videos where the sharpener used the paper test to demonstrate the actual or desired sharpness of his tool. Sometimes these tests went flawlessly and sometimes they indicated that more work was necessary. Any sharpener can have an off day. Jeff's paper tests were always flawless. I'm sure this was due to good technique, although using Tormek heavy brochure paper improved the success rate.
The hatchet trick with the chisel edge is quite impressive. Again, experience and good technique carries the day. I am also quite sure that Jeff had optimized his grinding wheel with judicious use of his stone grader. (Never a bad idea.)
