So the question is, how many shaves can you get out of a Dorco ST 301 blade before disposal? Well.. I sort of know the answer, at least for my experience. ZERO! What a terrible shave that was with a brand new blade. I am glade that I never just ended up with them to begin with. If I did I think I would have given up on DE razors. It tugged and pulled right out of the wrap. It did give more sound tho, almost like it was cutting more at once then other blades.. That sound of buttering toast was very loud. Loudest out of the three blades I have tried thus far, which are the Merkur, Derby and Dorco. So far the Dorco's are dead last and I am not even sure I will try them again.. Time to try another brand. Glad I took the recommendation for samples. This is proving to be very useful information to know in order to enjoy my shaving experience forever more.
