Have asked this question on several sites and have never recieved an answere.
Why is it recomended to use oil on a Charnley and not other stones?

it appears to give better edge with oil.
Most stones from the UK were traditionally used with oil afaik, the reason could be that some stones are hydrophobic and when you use oil for sharpening your tools won't rust.
Not all CFs are hydrophobic but some really don't work with just water.
You can use oil on coticules too since they're non-porous and it works just as well...
Oilstones
Waterstones
Simple as that,,,
You can use water on an oilstone without ill effects, sometimes using a bit of soap to create the glide, but most waterstones should not be used with oil as it clogs the stone....
I don't like using oil on any stones at all. I find it is messy. I have also found that in the alternative where the stone appears to reject water, ie. hydrophobic as Piet says, a little dish soap or lather mixed with water can solve or certainly reduce the problem.
I use my CF with oil. And that's the only hone I use it on...
great big +1. I'm a soap and water on Charnley guy. Damn fine edge. Damn fine.Quote:

I have to agree with use of oil on CF could give better edge. It also appears that lover grit CFs with oil prform much better than with water. But it is messy and I prefer water. However I am already deciding which one I will use with oil. Just for heck of it.
oil helps with reducing resistance on the stone i use oil on my translucents arks surgical black ark and cf
Both oil and water are used as lubricants when honing, it is the nature of the stone that dictates wether it is preferable to use oil or water. Although I am a big fan of the Charnley's capabilities I prefer my water stones. The subsequent mess is far easier to clean.
Lets just talk about my CF:
A CF was my first finisher and if I were to have to give all stones up but one, I would keep my first. I've used my CF with both water and oil and the reason to use oil is to make a CF stand out in the crowd. You must remember that CF's are slow stones and require a lot of laps to get your razor just right. With water, there are better stones, particularly a thuringian. On oil a CF is simply amazing, but you must be patient. I have experimented with water, 3n1 (too thick), sewing machine oil (about right), Kroil (a bit thin), and a mixture of sewing machine oil & Kroil. I have come to like a ratio of 75% sewing machine oil/25% Kroil for my CF after a LOT of experimentation.
This stone is best used after 12K if you are using Nani's or 16K if you are using Shapton GS's. You will also hear that it takes a lot of passes, on the softer blades like the Sheffields I start with 50-75x & on the harder blades I start at 100x, adding 2-3 drops of oil to the stone at about 25x.
There was a very nice looking CF in the classified's the other day, may still be there. If it's there, you could contact the seller to see how that stone behaves as all natural stones have their own personalities.
For final finishing, I use oil on my Charnley Forest hone (and all novaculite) to get maximum keenness on the edge. No cutting slurry particles are suspended in the oil. There are several other final finishers that I use oil on as well. I use Norton Sharpening Stone oil.
I have no problem with it being messy. It is only messy when the oil stone is “not” your final finisher. Then you have to clean the blade of all oil or it will contaminate your next stone in the progression. Hope this is some help.
