I was told by someone very well respected in the lapidary and gemstone business that diamond wheels shouldnt be used at all on any metals ... like doing a knife ! That eventually it will pull out the diamonds ...Any thoughts  |

Not sure what you mean by making a knife with diamonds? seems like an expensive -- unnecessary route would work tho... in a pinch that said I once put an edge on my Swiss Army Knife at a community center on one of the cabbing machine The shop supervisor freak out ! :nono: I think he was little over the edge sort of to speak  sharped's |

I don't sharpen knives on my diamond wheels, but I do occasionally sharpen my pizza cutter on them. I haven't noticed any damage to the wheels, and it sure makes cutting pizza easy.

 I’ve done lots of pizza rollers! I had my own mobile sharpening unit at one time A ’64 Ford window van, killer generator, and all my sharpening equipment within. I could do everything from carbide saw blades to knives. Custom jobs I took home. But my big source of income was scissors work! Upholstery shops and certain hair salons. I sharpened from El Mirage to Apache Junction and all points in between. Kick myself for losing my set up it was a cool tho… as cool as grinding rocks! Name of the biz was: SharpEd’s  this wasn’t the place to mention it but I did anyways E

I don't see any difference in my belts or wheels. I grind a lot of metal when doing the scales, as the bolsters have to be sanded also.

I use a bit of spring steel to make knives with, grind them on my regular grinder to put their first edge and to shape them, then I use two levels of oil wetted stones to get the sharpness set up, then onto knife steel, and finish up on porcelain. Pretty much a surgical edge when I'm done. Have to be extremely careful not to cut myself.
I NEVER use my diamond equipment, other than my wetstones which two of them are diamond filled. the finer grades for finishing the edge. Those will really make a knife like a scalpel!

I have used my Genie to polish my hammers, does a nice fast job.
Soft metals like Aluminum might clog the diamond wheel, but than just cut some agate or dressing stone to clean off and expose the diamond again
They are now selling a lot of diamond tools for working in silver and gold.

Sorry guess I should have been more specific .. As rockmanken has mentioned ...doing scales while already fastened to the knife (not the blade but the housing) would mean some contact with the metal housing .. Well I am having some mineral specimens faceted by a wellknown in the lapidary community and was showing off some of my work and mentioned this ... I was given a big no no!!!!! Just looking for some advice here to follow up on that and see what others had to say !!!! lol ed ....

Well, steel and brass are much softer than agate. So should we not cut agate? I think that is what we bought our equipment for. Aluminum will clog up SiC grinding wheels in a heartbeat, imagine the same for our diamond wheels.
