Hi Thin-Slice,

Got your email, thanx. I'll know more when I get to inspect the stone next week when I return. I've instructed Customer Service to save the stone for me and to refund your shipping costs. I really just need to know for my own knowledge. If it's an anomoly or if your standards are just higher than our abilities.

Hi Thin-Slice,

Thanx for the update and glad that we took care of you. Sorry for your disappointment. I'm sure can also get your shipping costs covered as well.

Our 2 X 8 stones are "as fired". They have a tolerance that's larger. The 2 X 8 UF and 3 X 8 UF stones are ground flat using diamond surface grinders, the same that's used on your flat stones. We have had no complaints regarding the UF stones for not being flat enough. I'm travelling right now so I won't be able to get some on a flat surface, but I've not experienced the "bow" as you describe. I'll check yours when I get home.

I have never tried the ultra fine on chisels or plane irons. I may give them a shot, but that would normally be after using a coarser stone, like a Norton Lily White Washita.
 
Hi Arty,

That's what they were made for. They're quite fine in grit and are a final finishing stone.

Interesting. First time I've heard this come up. Always appreciate your responsiveness Sal.
 
I've got the 8x2 inch Medium, Fine and Ultra fine benchstones and the Ultra Fine does have a very very slight wobble when place on a flat surface and pressing down on the corners.

I'm not saying you shouldn't send it back but I have sharpened many a knife with the UF now and I can get crazy sharp results. For knives, does the very slight loss of perfect flatness even matter? I can't believe it does? Again, I know the stone is not technically perfect but I can't imagine anyone's free hand skills are so finely turned that there would be any negative affect on sharpening. Variations in consistent angle caused by non perfect hand position and motion during sharpening would seem to negate the stone's negative affect on sharpening.

No idea about chisels though.
 
I have chisels and some long flat metals i polish this way. Perform strokes with the length of the stone to cover entire surface but when the stone is not flat it messes it up a bit. However, as you say for folders i dont think it affects it much.
 
I remember the old guy who sharpened knives for my family and neighbours used a stone of a huge arc because the middle portion was worn so much more. Knives going off that stone were always razor sharp. Did not seem to be a problem for him.
