Is the Manticore an oilstone or a waterstone.Thank You in advance.

It is either, according to your preference. If choosing to use it with oil you may wish to make use of the petroleum jelly filling method to reduce how much oil you have to use on the surface each session. But I use mine with water, personally.

so just slather vaseline on the surface then add oil to saturation? or is the vaseline used as the oil?

interesting

You warm up some petroleum jelly to the point where it liquifies and absorbs into the stone. A hair dryer is sufficient for this. Do this until it's pretty full. When it re-congeals you now have it occupying the core space of the stone, reducing how much oil you need to apply to the surface.

FWIW, coming from a newb like myself, you can also use the oven. I treated one of my other stones as noted by FortyTwoBlades FortyTwoBlades above, using petroleum jelly and a hair dryer. I apparently didn't use enough, though, so I had to re-treat it. I have a ratty, rusty cookie sheet that serves as a "project sheet" these days. I was going to set the oven for ~130*, but my oven won't turn on below ~175*. Accordingly, I put a layer of PJ on top of the stone, set it on the project sheet, and set the oven to preheating up to 175*. Before it reached that temp, all of the PJ had melted and soaked down into the stone.

Thank you, Gentlemen!

How much and what type of differences in cutting should someone expect with this method vs water?

Thanks again.
 
Oil is more lubricating than water is, so it reduces wear on the abrasive, meaning you can potentially use lower pressure without risk of glazing the stone. Water is overall a bit tidier.
 
First use of my new Mantacore was surfacing 2 four inch 1st gen Venev 60 grit bonded diamond stones, a lot less messy then loose 80 grit SIC rock polishing media. Mantacore smoothed out nicely after a light hand with water. Much better then an old coarse Norton stone, um about 120 grit, in my opinion.
