The blade of the Helje is 20 mm so that must be 7/8 (?). I've always found inch system very confusing :p
On the back side of the Heljestrand there is 'M (three crowns) K. No 32'
Those 3 crowns are obvious as we are talking about the Swedish razor, but i do not know what MK means.
Maybe i just have to try to learn to live with the fact that the scales might be ivory. Sorry, poor elephant. One day he was walking happily in Africa, doing things that elephants usually do. Guess he never knew that one day he has to give away his life just to be my razor scales. Such a poor and useless destiny.
May the dust lie lightly on you under the earth, elephant.
On the Ward razor there's groove on the front side only. No markings on the back side.
