Handle Materials and Their Properties
Handle scales are made of various materials, including mother-of-pearl, Bakelite, celluloid, bone, plastic, wood, horn, acrylic, ivory and tortoise shell. Celluloid can spontaneously combust at elevated temperatures. Buffalo horn tends to deform with time and it possesses form memory so it tends to warp. Mother of pearl is a brittle material and can exhibit cracks after some use.
Plastic handles are flexible and can impact the blade if not handled carefully. To remedy this, some plastic handles have a plastic coated third pin at the center called the plug that acts as a bridge between the sides of the handle.
Resin impregnated wooden handles are water resistant, do not deform and their weight complements the blade's to provide good overall balance for the razor. Snakewood, Brosimum guianensis, is also suitable for long term and intensive use.
The mechanical properties of bone make it a good handle material. Handles were once made of elephant ivory, but this has been discontinued, though fossil ivory, such as mammoth, is still sometimes used, and antique razors with ivory scales are occasionally found (it is illegal to kill elephants for their ivory, but it is legal to buy an ivory-handled razor made before 1989).

Famous quotes containing the words handle, materials and/or properties:
“If parents award freedom regardless of whether their children have demonstrated an ability to handle it, children never learn to see a clear link between responsible behavior and adult privileges.”
—Melinda M. Marshall (20th century)
“Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.”
—Jane Jacobs (b. 1916)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
