Thread: Shaving follow-up to 'For Free: But you have to "Pass it on"'

There could be variation in the weight caused by different scale materials and thicknesses, as well as the grind of the blade (1/4, 1/2, full hollow), and spine thickness.

I just use whichever part of the blade works in a given area, no charts necessary.

Glad to know it's working out for you though!

In general given the same grind a 5/8s or 6/8s will be pretty similar in weight in their respective size class. It has to do with the geometry of the blade. As you go to different grinds that changes fast and you can get a 6/8s wedge that weighs many times more than a hollow grind 6/8s. Of course the scale material will change the overall weight of the razor itself but ideally you want the blade and scales to be balanced for weight. A razor that is scale heavy is no fun to use.
