WATER GLASS BLADE AND RAZOR WITH THE SAME

摘要

PURPOSE: A blade using silicate glass and a shaver including the same are provided to offer effect like exchanging a new blade without replacing the blade by using the silicate glass of which surface is progressively molten by contact with water. CONSTITUTION: A cutting part(110a) is formed in a tip of a blade for cutting an object by contacting with the object. A part or all part of a body of the blade(110), which includes the cutting part, is made of silicate glass. The body is made by combing two kinds of silicate glasses having a different water solubility.
