I always use tape. I generally use three layers because I've been practicing my counting. Sometimes I use five layers because I want to
stretch my memory a bit. Then sometimes I forget how many I used on the razor the last time. I try to make notes that tell me how many layers I used on each razor, but sometimes I forget. Then sometimes I forget where I put my notes. I think I'm just going to stop honing. This is all just too complicated for me.
