Toko Edge Grinding Rubber

This is a must after any edge tuning...polishes them up very nicely. I suggest using a fining stone very lightly before this, but then doing a full buff with this. Also, this won't work well for de-tuning (use a stone), but helps smooth things out afterwards. If you're gonna bother tuning your own edges, do it right and don't try to finish with a file.

I read the other review and respectfully disagree, but not because the reviewer is wrong. The purpose of this gummi is to remove light rust, light burrs and to polish steel edges. It is meant to be a follow-up, if need be, to a coarse, medium or fine diamond stone, tools that are intended to remove the big burrs and smooth very rough imperfections on the steel.
I use this gummi for polishing and detuning with very good results and have been using this or one like it for a decade.
Perhaps the fault lies with the marketing types who have given this item the name "edge grinding rubber". Leave off the word "grinding" and you have an apt description of the tool.
Shame on you Toko. Tell it like it is.

I bought this a while ago, and let me tell you, unless i'm using it wrong, i flat out find this useless. It's way too soft to be used as a gummi stone to remove and burrs. If you wanted to use something to polish, you COULD use this i guess, but i'm just gonna stick with my diamond stone. I personally don't like this, and as hard as I may try, i can't seem to find a use for this
