I can't believe that some people like this blade, but perhaps that is due to the razor they use. I used a Muhle R89. I used the Vietnamese version of this blade, and it is by far the worst blade I've tried in the R89. Very dull, rough, and lots of tugging on the first shave. Seriously, the first shave with this blade was worse than a week old [insert your third-favorite blade here]. I used three blades (each for four shaves), and then after the first shave on my fourth blade I decided to give up. I won't use the last blade in the box, and I wouldn't recommend this to anyone. Just awful!
