What's new

It's a dish that looks like a coti, a coti-dish, a dishy-coti

Ok so wadda I do? It's well dished but I ran a razor across it last night and it feels lovely. $ECD0E1DA-EE17-44DA-B96B-83D3F9FE4DC6-1270-0000029075D2AF58.jpg$9C62D213-A0E0-429A-B37F-5BECD1EF6EC7-1270-000002907B61F0B5.jpg$7E9BBA7E-BC4E-43B4-BF2F-65F42275977C-1270-000002906FD0A58C.jpg$ECD0E1DA-EE17-44DA-B96B-83D3F9FE4DC6-1270-0000029075D2AF58.jpg
 
Coti frown..hehe..dmt325 for awhile should fix it..as long as blade edge makes contact with coticule surface..you should be ok
 
Gary, the problem is that the dish isn't uniform, it's like the corkscrew at Alton Towers! The middle is good but the edges are a little rounded.
 
Maybe I'll just admire it for a while, attack it with my belt sander when the missus isn't looking and try not to lose a finger at the same time.
 
is it really worth the effort to try to lap that flat?
I'd say just use it as is for kitchen/pocket knives

Or you could just use one end of the stone, some folks say a concave edge will last longer.
 
That's a beauty, it would be worth it to lap it flat to me. A shame that you can't use it as is. That dish would make a convexed edge not concave. A convexed edge on a knife is MUCH stronger and stays sharper longer. Would be interested to see how I would do on a razor.
 
i wouldn't lap it....

i would hone a couple razors and see how they turn out.... if they are good... the keep it up...

the problem with lapping that is your gonna lose a chitload of stone flattening it out....

just use it...
 
Ok, I had a good look last night and it's not just dished lengthways but also crossways. I'm gonna try and lap it so that it remains more or less flat crossways but stays dished lengthways. Gonna be fun! One thing I will say is that it's a lovely shape to hold and seems fast on water when I gave it a quick run on an old razor.
 
My suggested approach would be to cut off a section from the thick end, then lap the rest flat. You'll then have two stones from the same grade: one for slurrying and one for the honing. Looking at your picture, you'd still have a very serviceable length one you've made a cut. Of course, the cut off would need lapping also.
