Ultra Sharp XL Double-Sided Diamond Sharpening Stone | Coarse and Extra Fine Grit

This is a solid stone to get any knife to a good working edge. "Working edge" being the key. Don't expect a 1000 grit to give you razor sharp hair popping edges, but this stone will get them pretty darn sharp... I use this one to get my edges sharp and profile quick, from standard stainless kitchen Knives to pocket knives made with premium super steels, this stone's medium side will reprofile most dings and such in a badly dulled blade, the fine side will get a good working edge on anything. Then with a nice sharp edge set, for shaving sharp edges I take them to a 2000/5000 water stone to polish them even finer...

works great

At first I thought this maybe a decent stone for the $50 mark. Man was I WRONG! Now I sharpen a lot of tools in my new hobby and I got tired of whetstone and the mess they require so I thought I’ll try this. It worked ok the first 2 dozen times but I noticed it got slower and slower. Now when I try to use it it takes me 15 minutes just to reset a 25 degree bevel on a plane iron! The stone has wore down to a fine on one side and a very fine one the other. It’s only been a month and 4 days. They say they have a lifetime no questions asked guarantee and I hope they contact me to make it rite, however I don’t know how to get a hold of them on amazon since the 30 days are up.

I've seen many videos on it and it works great. Took my hand planer's blade and worked in just 5 minutes to a very acceptable sharp edge. I would have liked the manufacturer to give their own usage instructions to make my confidence go up just a little more. Even give various options for ways to use their own tool on various items. Knives, blades from different tools, and the sort.

I have been using this since February and it works well to set and sharpen an edge. So far it has stood up well and still sharpens chisels and plane irons well, though the coarse side has discolored a little bit, I am not sure if that is rust or something else.

This is a good item however one side was supposed to be a fine grit on my item both sides are identical which is a medium grit. Good item but unhappy with both sides being a medium grit.

A glaring oversight from the manufacture to their customers, there are no identification marks anywhere on the stone to help identify which side is the 400 grit or the 1000 grit. Without any indication marks the user is left to speculate which side is which and if the stone is truly a 400/1000 grit stone!!!

This sharpening stone is much heavier than most diamond sharpeners and dead flat. The diamond pattern prevents prevents it from clogging. 400 and 1000 grit works great for preparing chisels before polishing with waterstones.
