The Bevel Razor is quite heavy. We strongly recommend using absolutely no pressure at all, the weight will do all the work for you. Also, there is a bit of extra care required around the contour lines. The Bevel Razor's head, of course, does not flex or pivot for you, and that takes a bit of practice to get down. The payoff is huge though.
Here is a great video that I think you'll find super helpful.
Additionally, short strokes are key! (above video shows this too). I know it's common to see guys in shaving commercials making quick long glides...you'll need to do just the opposite!
If you keep these points in mind, it's unlikely that you'll experience nicks like this!
