The MERKUR 500 Progress is a model from the 1950s. The ivory-coloured knob and the profiled handle tube correspond to this period. The shaving head can be adjusted using an adjustment scale. The angle of attack and blade gap can be adjusted from the gentlest shave to a close shave. So nothing stands in the way of your personalised and flawless shave. With a turn of the knob, you can adjust the blade gap according to the setting scale from coarse for long hair to gentle for everyday shaving. Completely customised to your personal shaving sensation.
