I took some hollow grinding lessons from a knifemaker buddy of mine today.
This is a copy of a loveless style knife, it was sure nice having him show me some tricks and guiding me through the grinding process.
I'm real happy with the outcome! After heat treat I will fine tune all the lines.

Not bad, pays to get around some experience.

Personally for me, it applies to all grinds but especially hollows, you can really "feel" where you are at and the response of the wheel. Once you get that feeling... its second nature, and for me, I hollow grind every blade unless requested not to... I just prefer it.

I like the look of a hollow ground blade, but you are limited to the length of time you can sharpen it. I make mostly hunters and hollow ground knives don't work we'll for that IMO.

I would say that a flat ground hunter is as good as a hollow ground and could even be better but a hollow ground hunter is fine as long as you use good steel and the right heat treatment. I made a 4" hollow ground hunter from O1 and sent it out with some guys going on a guided hog hunt. Their guide used that knife to dress seven 400 pound hogs without needing to sharpen the knife and hogs are very hard on edges. I doubt any ordinary hunter would wear that knife out in one lifetime of normal use ....

The reason I ask, correct me if I'm wrong. But it seems to me that a larger wheel would extend the grind? Heck I don't know! I'm a rookie. Lol!

I do all my hollow grinding on a 10" wheel unless I'm making a pen knife sized blade. All the 4" hunters on my site were done on a 10" wheel (except for the few I flat ground, of course ) A larger wheel does make it possible to more easily extend the grind meaning that it is easier to hollow grind a wider blade if you have a bigger wheel. BUT, with practice you find out that it is possible to use a smaller wheel to hollow grind a wider blade than you would normally attempt with a smaller wheel by angling the blade across the wheel....

Actually its just the opposite .A hollow ground blade stays thin longer than a flat ground blade .A flat ground blade will immediately start getting progressively thicker as you sharpen your way up the blade whereas a hollow ground blade will remain thin for a while and then suddenly become exponentially thicker.
