Deformation:
If any metal parts or metal devices are deformed in any way (compare them with the same, unused model), the product should be retired.
Abrasion:
If abrasion on any part of the product is more than 10% (compare with same, unused model), the product should be retired.
Burrs:
Burrs and other sharp edges must be filed off using a needle file. However, the maximum amount is 10% compared to a same, unused model. If the damage exceeds 10%, the product should be retired.
Cracks and Fissures :
If visible cracks or fissures are seen on the product or its components, the product should be retired.

If any metal parts or metal devices exhibit corrosion or oxidation, the product should be retired.
Pins and Springs:
If any metal parts or metal equipment show pin deformation, or other damage listed above, or if the springs do not work properly, the product should be retired.
