直式剃刀

直式剃刀是一种可以將刀片與刀柄折疊在一起的刮鬍刀。由於直剃须刀相對於其他款式的剃鬚刀要更危險，所以男人在使用直剃须刀剃须时要更小心。 1680年，谢菲尔德出現了全球第一把钢刃直式剃刀。直至20世紀中葉之前，直式剃刀一直是全球主流刮鬍刀，後來由於安全剃鬚刀和電動剃鬚刀的興起，直式剃刀不再是主流剃鬚刀。ohiokids.org by the Ohio Historical Society, 1982 Velma Ave. Columbus, OH 43211-2497 (through the Internet Archive) quote: "Today, men usually shave with disposable razors or electric razors, but that has not always been the case. For more than two hundred years, most American men who wanted to shave used a straight razor, also known as a straight-edge razor. This type of razor first appeared in England in the 1700s, and remained the mainstay of men's razors until the twentieth century. 1979 年，荷兰研究人员发现直式剃刀剃掉的毛发比电动剃须刀剃掉的毛髮要短约0.002 英寸（0.05 毫米）。
