I sharpen knecker knife once year an put bur on edge after. With lansky 5 PC hone set an angle guide, out lite hone oil , wonder be best. Water. Wd 40, or 3 in 1 oil?

WD 40 will work but tends to soak in to some stones fairly quick,Watered down dishsoap is good.3 in 1 oil is a bit thick,but you can thin it with a bit of kerosene and it will work.
Anything that will float away the particles and keep the stone clean and not clog up.
Keep your stones dressed regularly so they dont get dished. A cheap flat diamond steel from the dollar store is good to dress your stones.Use water when dressing the stones.

We always used soap at the slaughterhouse

Wd 40 is ok if keep stone soaked ? This is a 1 time a year thing

I dont think you want to keep em in water if thats what you mean, it could damage them. Only store waterstones in water.

If you have like a good arkansas stone wd 40 will be ok.Just keep it wet.
If you have one of those synthetic stones the wd 40 will soak right in like a sponge.

I use gun oil

I use kerosene from a small jar (a yeast jar actually) and put it on the stone with an eyedropper. Whatever you use needs to be thin but float the fines. WD40 works good too but is expensive in comparison and gets messy from a spray can.

Cheapest most available oil is diesel. But I prefer soapy water, I always end up with a cleaner stone. 5 or 10 weight motor oil or machine works better than WD40 because WD40 is really too light to carry much slop off, and just carries the superfines deeper into the stone.

I’ve used Wd 40 as wasp killer, gun oil, cologne, hand cleaner, parts cleaner, 22 target...

I use norton honing oil.You can buy a can from Walmart for 9 bucks and it’ll last you well probably 10 years lol.

A lifetime an then lot more. Not worth $9to Me, my tri hone for skin knife. Use water

I use 3 in 1 oil on a Norton India stone for my woodworking tools. Mostly use a carborundum and water on my knives.

Come on thats only 2 coons to pay the 9 bucks

Walmart don't got nothing, never hesrd it, I call dicks, they have Smithfield hone oil, non petroleum , is that ok on lansky on a knecker, ? 3 in 1 oil is petroleum based ? The old stuff was lire like water but gone. I just dont wanna screw up blade , Smith or Smithfield hone oil can be used on arkansaw, stones I thought guy dicks say on phone. Is vegetable oil the same ?

dont use vegetable oil

the smiths honing oil will be just fine.

Don't use WD40. That stuff evaporates and leaves a wax like residue on and in the stone. The last thing one needs is sticky stuff on a sharpening stone.

Boco is spot on. Never thought of soapy water.

The tri-stone I bought a couple years ago came with mineral oil. Works good.
