I'm testing the "King C. Gillette" DE blades (Made in Russia), for the first time.
I took my gentle storebrand TTO (Baili TTO) and my beloved transparent (glycerine) body soap and of course my greybadger brush.
This DE blade is def. solid sharp, but NOT gentle!
This blade is NOT FOR ROOKIES!
I have some nicks, mostly around my chin, but not serious ones. I did absolutely right to handle this blade with respect! And I just can recommend you to use a gentle DE razor with this blade, too!
As comparison, I will try again the classic "german" Wilkinson Sword DE blades, the next time on the same TTO razor.
