A glass nail file device and method for making a glass nail file wherein the glass nail file includes a glass-like substrate, a permanent grinding surface formed in at least a part of at least one surface by a chemical etching process and a handle defined by the substrate. The process of making glass nail files includes providing a glass or glass like substrate, chemically etching at least a portion of at least one surface using a solution that includes dissolved salts or some other aqueous solution of hydrogen fluoride that facilitates an ionic exchange between the solution and glass substrate.
