Simple question about guided diamond hones

Hey all, I never gave it too much thought but recently realized that my diamond hones for my lansky are magnetic. I am looking for diamond plated hones that have a non-magnetic base. Do KME, EP, and WE diamond hones have the abrasive on a magnetic base? Is there any other guided diamond hones that aren't magnetic?

None of the sharpeners you listed (KME, EP, WE) use magnets... at least not the original equipment versions... that I'm aware of. WE stones are glued in to their holder... KME and EP use a clamp system to hold the stone.

Also the diamond plates for the WSGSS from Worksharp aren't magnetic (but their is a small magnet in the base to help hold the stone).

Edit: In case I misread your question... and that you want a stone a magnet isn't attracted to?... the only one I know of are the Venev stones... they're a bonded stone on an aluminum base.

What do you mean "magnetic"? If it is plated diamond then it is on a steel backer which may develop some magnetism. I know the EP Matrix stones are only resin, diamond, and aluminum backs so no chance of any magnetism.
 
I know my KME Gold Series stones are not magnetic I tried them a while ago and I know they are steel but I'm guessing they are made from stainless steel,what I'm interested in is what the reason for them being non magnetic.

Hi,
They have been magnetized by friction , see Triboelectric effect

Dry grinding will magnetize thin nickel plated steel diamond sharpening stones.
Esp those mounted on plastic.
Even blades will get magnetized.

If they are not magnetized they won't hold on to iron filings (swarf from sharpening) and so the stones will be easier to clean as well as . . . as was stated by Buckstove, the knife blades won't end up becoming magnetized from rubbing them on the plates which sucks because then the swarf sticks to the blades.

That makes sense about not wanting the swarf to stick to the blade.

Hi,
well even when it sticks it wipes off relatively easy

if you're dry grinding, all the dust that sticks is dust thats not in the air going into your lungs :)

i've been using oil lately and i like it a lot better than water cause it takes only 1-2 drops
dip q-tip in oil, rub over the stone, good for a thousand strokes, wipes off easy
 
Thanks for all the responses. I worded my question a little bit misleading. Yes, I meant diamond stones that magnets are not attracted to, not magnetic. So, I think I'm hearing that EP and KME fill that requirement?.. Or are the KME still made of steel?

As far as the reason why, wade7575 wade7575 , I'm hoping we will both find out down the road a little bit... ;)

Edited.
 
If it's just a concern about swarf sticking to the hone (or blade) and clogging it, a little oil on the hone will cure that. Simple fix. The hone will cut better for it. Just a thin & light sheen of oil, not even enough to drip from it, will keep the hone from clogging. I use my diamond hones this way with some mineral oil, for this reason.
 
If your diamond sharpener are magnetic, hold it hanging down with your fingers, use a small hammer, give the sharpener a blow on one of its corner on its down side. The blow shall be fast but not hard, it is better with a small hammer then a big one. The blow shall create a vibration of the sharpener.

Done correct, the magnetism dissapear.

You can magnitise a screwdriver by slide a magnet along it 3-5 times in one direction - and demagnitize it again by this method. Nice to know when you like your screwdriver hold a screw on its tip.

I kinda thought when I reread your first post, that's what you meant.

The older EP diamond stones... a magnet will stick to. I don't have the ones Diemaker described, but they sound similar to the Venev stones.

I have these stones... and a magnet will stick to mine... so maybe find out if they changed how they're made? (Mine are 5 or 6 years old).
 
I forgot to mention that the Venev resin bond diamond stones also have no materials that a magnet could stick to.

The only way I know of that will remove magnetizm is a real demagnetizer, cheapest I have seen are around $50. Tapping on the parts does nothing and rubbing a magnet on a steel part will only magnetize it. It doesn't take much to impart some magnetizm to steel parts.
 
Mine are about 2 years old.

My personal concern is not about the swarf sticking to the blade, but rather for a project I plan to begin working on in the near future. If all goes well, I will report back on it when it's complete.

I think I might know at least one direction, where one might go with this...

It'll be interesting to see what you come up with.
