6th shave this am with VIking Sword blade #3 in my pre-WW2 Tech. It was a smooth and close shave of 2-days growth. But efficiency had diminished enough that I called it quits with the blade at the end of the shave.
My whiskers seem to wear out blades faster than average, although I did get significant longevity from the Viking's Sword Blade. So I understand about noticing blade roughness before reaching the average shave count for blades.Used the Viking Sword blades in my Game changer .68 or Rockwell 6C on plate 3 the two razors I like to test blades with. Hot shower followed by lathering some Stirling Gin and Tonic in a bowel then face. First use was always fine but after that it seemed to get rough and by the third use they were done. I can use Gillette Silver Blue or Gillette Green for 3-5 shaves without a problem so will stick with them. Thanks go to Space Cadet for supplying the blades and Grundi for running this participation PIF and mailing the blades out.
