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 there is a species which is more maltreated than children, then it must be their toys, which they handle in an incredibly off-hand manner.... Toys are thus the end point in that long chain in which all the conditions of despotic high-handedness are in play which enchain beings one to another, from one species to another—cruel divinities to their sacrificial victims, from masters to slaves, from adults to children, and from children to their objects.”
—Jean Baudrillard (b. 1929)
“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
