Much tool for little money. You can see the small part not to, but it works! Calm and steady the cutting by the respective slot pull until the cutting angle is right, then regrinding with the ceramic side. The blade is really sharp. Who then subtract correctly by leather straps and paste dieFreude finds his formerly dull blades again. Unconditional purchase recommendation for those who do not feel called to be absolute professional with expensive grinding grindstones!
