Thread: Rounded stones...

So I was tooling around on Dovos web site, and noticed something interesting.

You know the synthetic stone they use after the mechanical sharpener we have seen in the "how its made" video? the stone is round, somewhat like a sword polishers stone...

You can clearly see it on their web site home page, where the advertisement keeps going by. It is the second one. The stone is CLEARLY rounded over, to the point where it looks intentional. I was thinking... that would really be interesting to try out, you could pin point exactly where you are sharpening the razor without wearing other parts of the blade...

Is their stone just incredibly out of flat, or is this an old way of doing things? here it is.

No idea about Dovo's stone but you can know exactly where you are in contact with the hone on a flat hone. You can work specific parts of the edge on a flat hone without compromising the rest of the edge.

i see what you mean. I suppose it could be handy for a wonky blade but not a necessity. I'd rather have a flat stone for the sake of hitting everything at once. Like Bobh says, you can do the same thing with a flat stone.

I find almost none of my razors hit the stone all at once, that would mean they are perfect, its just not a perfect thing. What do you guys think about this though? Do you think the curving in the stone is intentional or not? Thanks.

Ever wonder why Dovo "shave ready" razors always need to be professionally honed on the first day you get them? now you know.

HAHAH. Good answer. I have owned 3 dovos that were NOT pro honed, out of the box 2 of them shaved great, one of them just okay. I know a lot of people have issues but mine have all been good.

It looks to me like the stone is just dished from use unintentionally but doesn't get lapped ever.

Funny picture. Convex hone, very coarse scratches. Razor looks like it has a lot of honewear.

Looks intentional, but I can't think of any advantages a convex hone could have. You'd only be making contact with a very small portion of the blade with each stroke, which I would imagine leads to many more strokes to get a finished edge as opposed to a flat stone where you're generally working a fairly large section of blade at once.

Convex hones were common to hone razors back in the day. Both my Dad and grandfather used a convexed Thuri and Ark to hone their razors. Unbelievable edges and bevels. I used them all the time. Unfortunate for me the disappeared in transit on a move across country along with some of their other shaving paraphernalia I had saved. I have dabbled in making some myself. A lot harder then you think. My old man could do it by hand with no jigs.
