These sticks are awesome, I’ll have a belt start degrading in cutting performance and hit it with the big eraser and you can literally see the belt go instantly clean, and then start throwing mad sparks again…. Sometimes when the belt gets really clogged with hard wood and dried epoxy or melted resin scale material it won’t remove it all but it still does a great job of making the belt cut way better then it did before… I’d highly recommend this product, I won’t grind without this next to my grinder, works on all my belts large and small..
