The MERKUR 510 is the long version designed for larger hands and is also based on a model from the 1950s. The ivory-colored knob and the contoured handle reflect that era. The razor head can be adjusted using a scale. From the gentlest shave to a robust clean-up, you can set the angle and blade gap. This way, nothing stands in the way of your individual and flawless shave. With a twist of the knob, you can adjust the blade gap according to the scale, from coarse for long hair to gentle for daily shaving. Tailored to your personal shaving preference, whether for complex facial shaving or body shaving.
