Razor
From Memory Alpha, the free Star Trek reference
A razor is a device used to remove body hair, most often associated with shaving beards.
Lieutenant Malcolm Reed was of the opinion that an officer at his best should always be well-groomed. When he and Commander Charles Tucker III were stranded in the Enterprise NX-01's Shuttlepod 1 with no hope of being rescued in time, Reed still insisted on shaving his beard with a razor so that his body would look well-groomed when found. (ENT: "Shuttlepod One")
In early 2364, Data gave Geordi La Forge a razor that he adjusted to perfect efficiency. La Forge, however, preferred his regular razor, as he was of the opinion that shaving was a Human art form and that technological perfection could shave too close. (TNG: "Code of Honor")
Benjamin Sisko used a razor similar to La Forge's to shave his bald head from time to time. (DS9: "The Sword of Kahless")
Tuvok used a more old-fashioned razor blade adorned with alien writings. (VOY: "Year of Hell")
