Paste thinly on the leather, apply u. Can move in a few minutes. Wipe off the surface with a "old" knife and press the paste into leather. Now you can withdraw its "good" knife, ie result in a sweeping motion with little pressure on the leather.
The cutter is downright polished that looks really nice. And actually I could then shave the underarm hair. That was before, despite conscientious roughing, not.
For the price strong buy recommendation.
