Thread: Frictionites - other than #00s

I've got a friend who stashed away frictionites in the 1970s when he was on a tear trying everything he could find to get the ultimate woodworking stone (apparently, HAD isn't a new thing - he settled on spydercos back then as the best stone for woodworking). *I don't want any gauge on value*, I just want to know if the numbers correspond to stones suitable for finishing razors so I can list them properly. Figure that he probably purchased these stones in 1970 give or take, and he mentioned that he called and talked to someone at AM hone in moravia back then. He used one of them, and the rest he never used, and he said he thinks he has rub stones for them (which would suggest they're razor finishers). The only one of these he used was a #821.

He's got one or two? #00s still in factory baggies unused (I know they're good for razors, nobody needs to comment on those), and then he says he's got:
* an 825 (i think very large, like 8x3)
* an 821 (also, I think very large)

and another non frictionite stone that is labeled "super punjab"

I could certainly figure out pretty easily how fine these stones are by using them, but since most of them are unused, I don't want to do that.

He commented that the large ones were intended for razor manufacturers, perhaps someone at AM hone told him that.

Just to be clear, I don't stand to make a nickel on any of these stones and I'm not selling them here no matter what, nor will I make mention of them if he decides he wants to unload all of them, they're his stones and it's his business. He is not a shaver, so he's got no use for them.

My only request is to find out whether they're finishers or prefinishers so i can tell him what he's got and give him advice on what to do with it.
