Why do some blades chip?

November 30, 2017

There are three possibilities to consider when a blade has chipped or the point has broken off:

  1. The blade has a coarse grain structure, a result of overheating during the construction of the blade. Blades with fine grain structure typically will be stronger, tougher and offer better edge retention.
  2. The blade has fine grain structure but has been insufficiently tempered, a process that compromises hardness for toughness.
  3. The blade has fine grain structure, and sufficient temper, but was pushed past its performance limits with respect to its edge geometry. This can be remedied by removing some thin metal from the blade’s edge by sharpening.
