Hi everyone, sorry for my bad English but will try to explain so you understand. I wanna try to sharpen some junk knives with Dremel and would like to know which polishing head Accessory for dremel should i use together with stropping compound. I saw on some YouTube videos people use a big grinders with something like sponge surface for sharpening or polishing knives but never saw something like that on dremel. Anyone could show link or picture of how should that dremel accessory look like.
Thank you for help.

Those were probably paper wheels. Not sure if they make those for dremels. I've seen people use cotton polishing wheels I think it was to finish sharpening serrations after a stone but that's the extent I've seena Dremel used for sharpening.
 
They really should make some leather head for dremel for use with stropping compound...oh wait, maybe i will make it by myself. I only need to know whats best material for it. For polishing i guess the best is cotton but what about sharpening ? Leather or some sort of sponge i saw others use on big wheel machines.
 
ya know, that idea crossed my mind just today as I was combining a few dremel tool boxes into one. There was one box with three sized buffing wheel and a container of red jewelers rouge. and I thought, ok, what cheap A knife do I have to try this one,lol
Have'nt tried it yet though.....
 
I think the best for sharpening will be some leather wheel, but one problem with it . While for polishing its okey (because you can use upper surface of the wheel) , for sharpening little wheel is not good since there will be minimal surface touching knife edge and there is possibility that you will make hollow micro bevel BUT maybe its ok for micro bevel to be a little hollow ? If main bevel will be flat but micro bevel hollow i guess it won't affect its cutting capability ? Or maybe it will be even better ? or worse ? My logic says that hollow micro bevel means more metal erasure thus your knife will lose its wideness faster while cutting edge wideness will increase faster thus decreasing its cutting effectiveness.
Anyway ,if you want no hollow grind on micro bevel, wheel needs to be bigger.....finding bigger wheel for dremel is hard quest to complete )))


Edit : ok i found some bigger wheel for dremel but i guess its not allowed to link in this forum, but you can find it in Chinese internet shops

Yes but also bigger the wheel bigger the chance you will make convex grind, i think there is some most optimal size of wheel for sharpening knife that will be big enought to make sharpening easier but won't cross certain point after which it will begin to make convex grind.
 
No optimal size just optimal angle. but bigger the wheel... easier... and if it is for polishing, it must be able to take the whole width of the blade at least. without tearing the wheel.

no... bigger is the wheel more flat will be the contact area... smaller will give a more convex result but it is all in the manner and how steady you hold the knife, you can get a flat edge on a 6 inch wheel no problem.

I did overthink it again, yes it makes sense, the bigger the wheel the less curve on wheel/knife contact point. But i found only 4inch wheel for dremel, is it enought ?
 
And I would add Many say to secure the knife in a good vise but Me I would say secure the dremel in a good vise....
 
I'm considering using a file or dremel to put actual working serrations on the back of the 1095 ontario sp2. http://imgur.com/gallery/rqG3D0D
Not sure what idea behind the dull little teeth are. Should i use a conical dremel attachment? Carbide or diamond? Angle it up and in alternating sides? I want to reprofile the edge too. Hopefully i can make this $25 blade something great. Have you used dremels like that before?
