直式剃刀
（重定向自直剃刀）
直式剃刀是一种可以将刀片与刀柄折叠在一起的刮胡刀[1][2][3][4][5]。由于直剃须刀相对于其他款式的剃须刀要更危险，所以男人在使用直剃须刀剃须时要更小心。 [6]1680年，谢菲尔德出现了全球第一把钢刃直式剃刀。直至20世纪中叶之前，直式剃刀一直是全球主流刮胡刀，后来由于安全剃须刀和电动剃须刀的兴起，直式剃刀不再是主流剃须刀。[7][5][7][8] 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发要短约0.002 英寸（0.05 毫米）。 [9]

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.
