Additionally, the design makes it a little simpler to handle the blade while inserting it into the razor. Razor blades, however, should always be handled cautiously due to their great sharpness, especially while entering or withdrawing them from a razor.
Every kind of razor has a different precise design. While cartridge razors, disposable razors, and other specialist systems may utilise entirely distinct blade designs and fitting mechanics, double-edge safety razors typically use a common blade shape.
