Cut throat razor
Cut throat razors were once the principal method of manual shaving for men, they were over shadowed by the safety razor, which incorporates a disposable blade, or electric razors. Cut throat razors require considerable skill to hone and strop, and require more care during shaving. These methods were once a major portion of the curriculum in barber colleges. The cut throat razor has a straight steel blade that folds into the handle
Handles were made of various materials, including mother-of-pearl, bakelite, celluloid, bone, plastic, wood, horn, acrylic, and ivory.
The geometry of the blade can be categorised according to the following three factors: First according to the shape of the profile of the point of the razor, second according to the type of grinding method used for the blade; the degree of curvature, and therefore hollowness (or thinness), of the sides of the cross section of the razor blade depends on the method of sharpening. A leather strap or strop was used to put the edge on the blade, and the blade had to be held at a very precise angle and moved over the strop with firm strokes.
