When Were Razor Blade Slots Used?

The first razor blade slots were used in 1892. A German company, W.A. Schild, patented the design and began producing them.

The slots were meant to reduce the likelihood of cutting one’s own hand while shaving. Today, razor blade slots are still a popular design feature on many electric razors. They help guide the blade smoothly across the skin, preventing nicks and cuts.
