from my experience.....the most expensive belts last the longest....there is an exception....when grinding gummy material-aluminum, desert ironwood, lignum vitae, kingwood, some of the rosewoods, etc, the belts clog badly and are hard to clean...I buy the cheapest 50 grit belts to do handles with....but for stainless....the hoggers are good for profiling, the ceramic 3ms best to grind bevels with....but after the coarse belts...i dont like the ceramics in finer because they dont have good flex properties. so i switch to the blue ones after 80 grit. blue flex.....wish they would start making those in 600 grit....although the grey trazons or something like that come pretty fine....last forever. dont really know what that word is, cant remember...maybe trazac?? prozac??? something./

I like the REGALLOY belts. They last a good while.

Tom - I believe they are called TRIZAC (Heck, I ain't real sure either)

Do you hear that?
That is the sound of inevitability.
 
They are actually called Trizact..Mystery solved

They can be had all the way up to 1800 grit. (Not that anyone would really need 1800 grit).

i haven't found those other types of belts in 3"x132" unless i special order 50 of each grit. unless you guys know of any places where i can buy those belts in a quantity of about 3 of each grit, or 5. otherwise i have to stick with the ones i listed. I heard the regalite to be a good belt. thanks
tom, i'm only using these for flat grinding, i'm using aluminum oxide for sanding handles.

Magnum,
The Trizac belts come in numerous "grit" sizes and last forever, well, a very long time anyway. They cut differently and tend to be very agressive. About the closest thing they cut to is a file if I would have to try to describe it. If you haven't tried any of these, try a couple out. Here is a list of the sizes and the corelating grit size.

A100 = 180
A65 = 240/280
A45 = 360
A30 = 600
A16 = 1200
A6 = 2000

I tend to use the finer grits for finish work more than anything else.

As far as other belts go, Jim Lemcke with Texas Knifemaker's Supply mentioned that he carried Hermes ceramic belts a while back. I tried some out (60 and 80 grit) and they are really good, last a long time, every bit as good as the Nortons. These belts are orange which took some getting used to

I like the Norton Blue "Norzon" (I think thats what they call them). They cut good even after worn.

The Schroeder Belts that Peirce abrasives sells are decent, and very inexpensive, i think there $1.70 for 2 x 72.
