I like the larger area to test on

Just the regular stone. After 2020 one company makes them all.

Does exactly as we hoped.Good value, Good product.

The best, lead with integrity and honor.

It looked ok, i am sure it will be fine, buy I have not opened it up yet

Good size and easy to use

this testing stone does not work well it also cannot be buffed flatter to make it work better. The surface is too gritty. You cannot lay down a smooth or dense layer of metal to do your testing. I’m returning mine. It’s absolutely useless. Please see the video comparing my smaller stone that works infinitely better. I still want another stone that’s larger because I do a lot of testing, but I will find one with a better surface than this listing has to offer.

Decent size and non slip underneath. Works well.
