However, the heterogeneous nature of case hardened steel may still be desirable, as it can combine both extreme hardness and extreme toughness, something which is not readily matched by homogeneous alloys.

However, manufacturing limitations generally restrict such features to mass-produced blades fabricated of softer, less expensive stainless steel alloys.

However, such pickups lack certain sonic qualities found in other pickups, such as those that use Alnico alloys or more sophisticated magnets.
