1. Why does the blade suddenly collapse a blade when it is in use?

If there is no hard foreign object encountered, there are more cases where the temperature is too high during grinding and the "burned" blade is caused.

2 , the edge is a little yellow spot, the surface of the object being cut has a knife flower is the knife too soft?

When this occurs are mostly due to overheating, excessive local temperature to 300 ~ 350 ℃, here a metallic material generated cracks caused by shrinkage, does not mean the absence of invisible, the hardness of these regions must also have significant The decline, the inferior cutting will become inevitable.
