Experiments on 200 animals and clinical use of 300 scalpels differing in the width of the cutting edge showed that operative lineal skin incisions made with a sharp instrument (a ruby knife, razor, scalpel with a 0.8 microns cutting edge) heal better and quicker than those inflicted with a blunt scalpel of serial production with a cutting edge 12.5 microns wide. Such blunting of scapels occurs after two operations and traditional methods of sterilization of the instruments. Mechanical damage of the instruments during cleansing and washing is most important in the clinic.
对200只动物进行的实验以及对300把刀刃宽度不同的手术刀的临床使用表明，用锋利器械（红宝石刀、剃刀、刀刃宽0.8微米的手术刀）进行的线性皮肤手术切口比用批量生产的、刀刃宽12.5微米的钝手术刀造成的切口愈合得更好、更快。手术刀在两次手术及传统器械灭菌方法后会出现这种变钝情况。在临床中，器械清洁和清洗过程中的机械损伤最为重要。
