Could you post a pic of the silicone base?

Preyda have two types of black stone. Hard black and Surgical Black. I believe the Surgical is similar to what Dans sell, but I’m not sure how different the hard black is to that. I’ve not owned either.Is that good, bad or indifferent?
Oh sure. I have a number of slate stones I absolutely love.Oh well, whatever it is, it is going to be interesting to see how it performs as a SR finisher. For carbon steel baldes, it is only competing against pasted balsa and coticule.
I found some of the old discussion on this. It was Preyda. Apparently their Surgical is novaculite, and the hard is a type of hard slate called Dunston stone. They can still sell it as a black Arkansas because... well, it's black and from Arkansas.
This might explain the high SG and the fact you were able to get anywhere lapping it with paper. I tried lapping a translucent with paper the other day, and the stone just laughed at it.
Preyda's 'Surg Black' is typical of the most dense Arkansas stones. I have one he sent me to test, I kept it and got rid of all the others that were in the comparison testing.Preyda have two types of black stone. Hard black and Surgical Black. I believe the Surgical is similar to what Dans sell, but I’m not sure how different the hard black is to that. I’ve not owned either.
I do recall one seller (and I can’t remember if it was Dan, Preyda or someone else) selling a black stone from Arkansas that was actually something other than novaculite.
That's up to the user/owner to decide.Is that good, bad or indifferent?
the Non Slate black 'Ark' was not a good finisher,
My thoughts:May first try with the black Ark.
After studying the use of a black Ark here on B&B, I have decided to hone with oil. This will be my first time honing a SR with oil. Not liking the smell of regular mineral oil, I have bought a small bottle of J&J baby oil - the pure one without additives.
I have two identical SRs available. They are Titan ACRM-2 T.H.60 SRs, each finished off 0.1μm diamond pasted balsa strops. These SRs have a steel hardness of about 60 RHC. They shave identically and I cannot tell them apart based on the shave results.
My thoughts are to refinish one of these SRs (the one with the black tail) on the white (conditioned 1200 grit) side and see how it shaves. Is that the way to go or should I include the black (conditioned 600 grit) side before the white side?
Some other questions:
That's it for now, although I expect I will have quite a few more questions.
- How do I tell when the bevels/edge have been properly finished on the Ark?
- What types of SRs are recommended for the 600 grit conditioned surface and what types for the 1200 grit conditioned surface?
- What do I do to the honing surface once I have finished the honing session; leave it as is, just wipe any excess oil off, wash with water and soap, etc.?
- How do I tell when the honing surface needs to be reconditioned?
