About razor heads used

1920 Razors use brass razor heads made from Karve Shaving Co. ,Canada .

There are two kind of plates :

- solid bar (SB) plates (right below)

- open comb (OC) plates (left below )

 

In addition to the two different plate types, the Karve Shaving Co. 

razor heads employ 7 different levels of plates to adjust its aggressiveness.

The levels range from AA (the least aggressive) to F (the most 

aggressive).

Keep in mind that each level denotes a specific blade geometry, not shaving performance.

The geometry of each plate is as follows:

• AA - gap = 0.47mm / exposure = negative 0.07mm
• A - gap = 0.60mm / exposure = negative 0.02mm
• B - gap = 0.73mm / exposure = zero
• C - gap = 0.85mm / exposure = positive 0.09mm
• D - gap = 0.98mm / exposure = positive 0.13mm
• E - gap = 1.10mm / exposure = positive 0.17mm
• F - gap = 1.23mm / exposure = positive 0.22mm
