Questions for people who know abt knives:
i got in a couple of these stones from FT. Are they for use with water or oil, or is that choice just a personal preference?

i've never bought new sharpening stones before. Have gotten used ones over the years. Put a couple drops of oil on this FT one and was surprised that it soaked right in.

Is one supposed to saturate the stone before use?

i've always used an old tin of gun oil for my sharpening stones. It's really old so it's just light mineral oil, no silicone or synthetics in it. Now i'm coming near the end of the tin so am wondering what to get next. What's the recommendation? How abt regular vegetable cooking oil? Olive oil? Just water?

As far as these stones go, i haven't used them yet so can't say abt usage. It's a reasonable size tho. i thot they'd be smaller and more iffy. It's large enough.

Not too crazy abt it being two different grits, but what the hey.

Comes fitted into a silicone rubber base which is a bit sketchy. Think it'll be fine.

I use oil with planes and for chisels, but for knives, water; and I use them specifically for each, so two stones at any time. The one for planes and chisels has to be flat. The one for knives will eventually become concave.

It's just a personal preference. :)

Hi, yes you can use oil. (Gun, or mineral, no olive or vegetable). You can also use water, but once you choose one, stick with it. In my opinion water is the best option. Soak your stone in room temperature water for 10 minutes or so. Start with the rough side and Finnish on the fine grit. If you want to take it a step further you can then backstop the knife on a peice of leather to get a ultra fine edge. My knives will cut you if you just look at them funny. Even an axe can be sharpened sharp enough to shave with.
Have fun, keep your angles and strokes even...oh and keep some band aids around 😉

If you grind your stone against rough sandpaper, you will "true" your stone, making it flat once again. It should be done every once in a while when the stone starts becoming concave.

Water is much easier to remove the filings from, well it doesn't collect it as much.

What i have in the garage wrapped up somewhere are old Arkansas stones. Prolly older than me. Haven't used them in ages having gone to diamond hones.

Know how to deal with natural stones, dunno anything abt the man made ones hence my surprise that this one sops up the oil. i expect that carborundum will give me an edge much quicker than a natural stone; is that true?

Since you guys recommend water, then water it is. How do i clean the swarf out of the stone when it clogs up?

The man made stones are actually much better than natural stones. Natural stones have microscopic imperfections that will effect the edge. Still great stones though, and some people swear by them. The swarf can be cleaned away with water. I stop washing it away about halfway through sharpening. The extra swarf will help to get a great edge, and give it more shine. The swarf raises the stone to a higher grit.

i personaly dont use any liquids after i fucked up my first stone block. "lubing" up the stone before sharpening caused the block to get concave really quick and easy, plus it never sharpened as well as it being dry. only time i ever "rinse the block" is after i use it for wood or glass(yes, i sharpen wood and glass with these types of blocks) to get the splinters out of the stone for my next use.
Knock knock, let the devil in. Malevolent as I've ever been, head is spinnin'. This medicine's screamin', "L-l-l-let us in!"

So you use the stone dry, Skeeeets? How do you deal with the swarf that builds up?

edit: btw i just sharpened a little 2in. kitchen knife dry on this stone on the #2000 side. Really quick. Didn't need more than 7 or 8 light passes each side.
