I started with a disposable, this time
When I first started with a straight I didn't do to well. I didn't know if there was something wrong with my razor, or if it was my technique. This time around I bought a heap of these cheap disposables. The label say it is a Sayuri. They cost me 5 baht each (which is about 1/6th of a USD). This way I knew if it didn't work it was my technique. Then when I was happy with the result I switched back to my Dovo.
The straight is a world better than the disposable, but great thing about the disposable it eliminating a variable when you are learning.
