If you can handle pros instead, keep your eyes on overseas vendors - especially for the lower grits. There are still sellers in japan who are selling them at decent dollar levels.

I wish I would've gotten into this hobby early enough to get a nice coticule about 8 inches long and 2 1/2+ wide!

I agree with alex - when you start looking at dollars per abrasive MM, they're expensive stones! Not a big deal for them to be that thin if you're only doing a few razors, but the 1k glasstone is pretty soft, and over in the woodworking side of the sharpening world, people wear them out pretty fast.

I don't know if the glasstones are used much in japan, maybe they are, it just always seems like the sellers actually in japan push pro series stones more than glasstones.
