1、 The difference in appearance: In fact, it is not necessary to look at the appearance. The biggest difference between the two types of knives can be seen from their names, which is the difference in the number of blades, namely single and double blades.

2、 The difference in processing speed: As the number of cutting edges directly affects the speed of cutting, the processing speed of a single edged knife is slower than that of a double edged knife.

3、 The difference in machining effect: It is precisely because there is only one blade that the cutting surface of a single blade cutter is smoother, while for a double blade cutter, there may be differences in cutting angles and cutting heights between the two blades, resulting in slightly worse machining surfaces.
