The Merkur Classic (33C) is a classic Double Edge scraper as it looked in the early 1900s.
By appearance, it looks a lot like the HD with a barely so strong grip. The classic is made of steel and with a deliciously grooved pattern that ensures a good grip - even with wet fingers.
Unscrew the shaft, open the head and install a new blade. After that you are ready for a real shave.
