Anyway, getting back to hollow versus flat grind, I do believe it is more difficult for a custom maker to put a flat grind on than that of a hollow grind. I have a few of Bob Dozier's knives. He primarily uses a hollow grind on his knives, but will put a flat or convex grind on a knife if requested, but he charges quite a premium for doing so.

Likewise, the machine is equipped with precision electronic probes to correct the wear of the grinding wheels with an accuracy of 0.01mm.

What he needed to add was that it is essentially the grinding method preferred by woodworkers who freehand hone their blades. A hollow grind will self-jig the blade so that it is supported on the sharpening medium. A hollow grind automatically created a microbevel, which reduces the area to hone, making sharpening faster.

Radius of Hollow. For Radius of Hollow sharpening, the skate is ground on a wheel that creates a concave groove in the skate. The depth is determined by the relative radius of the wheel to the blade. As was covered in our previous blog, a deeper hollow provides for more grip on the ice. This is created by using a smaller radius on the cutting ...

What most do these days in terms of a "hollow" grind stems from what a production knife company came up with a few decades ago..... a hollow that does not extend to the spine of the blade (sometimes only 1/2-3/4 of the blade is hollow ground), and leaves the edge overly thick, necessitating very large/obtuse edge bevels.

In order for this to happen correctly, the gear must be ground on a beveled wheel which creates the hollow grind.

Hollow grinding goes back to the era when most home grinders were six inch (150mm) diameter. At that smaller diameter, the hollow is much more pronounced. This facilitates "two point" grinding. In my opinion, one can essentially ignore the hollow of a 250mm Tormek wheel.
