Hi Folks,

Several days ago I posted an inquiry regarding small hones for sharpening mortise chisels. I have finally found on the Web, at Hartville Hardware, a wonderful tool and hardware supplier in Ohio, a set of the small hones for which I was seeking a source. I thought I would post this link in case others might be interested.

I’ve read that when sharpening either hollow mortise chisels, their augers or forstner bits one only sharpens the “inside bevel”. Is this information incorrect? If not, how do these stones allow you to do that?

Thanks

hollow chisel mortiser bits need to be sharpened with a special type of guide that is inserted into the center of the bit. These come in the various inside diameters of the bits. The sharpener has a hole in the center is at the proper bevel. This is slipped onto the guide and then turned so that the entire inside surface of the bit is sharpened symmetrically.

Here is a link that shows this sharpening system: http://www.toolzone.com/acatalog/info_RL635_9600.html

Also, I believe al types of drill bits are sharpened on the inside edges or tip. Never on the outside.

Here’s another link to the bevel sharpener with centering cylinders:

I’ve ordered one of these that has two diamond abrasive “cones” without centering cylinders:

Here’s an article showing the use of the little hones for prepping hollow chisel mortiser bits and chisels.
http://www.taunton.com/finewoodworking/SkillsAndTechniques/SkillsAndTechniquesPDF.aspx?id=26261. It was this article that set me on a search for the little hones.

Articles I’ve seen on sharpening all emphasize sharpening the insides of the chisels and bits so as not to alter the sizes of the bore or chiseled mortise.

Anyone know of other sharpening hints or tools, bring ‘em on!

Best,

George Roland
