Striking Wrenches
Examine the box end of the wrench to ensure there are no cracks or broken areas. Wrenches that have been broken should not be welded up, but should be replaced.
Striking Wrench
The striking area should not be mushroomed to the point that splinters or shards will break off when they are struck.
No home built attachments should be added to the wrench, as this may cause heat damage making the wrench more brittle and prone to breakage.
End Wrenches
End Wrench
Wrenches should not be bent or otherwise deformed. Teeth on box end wrenches should be sharp and well defined.
Jaws on open end wrenches should not be bent or misaligned. End wrenches should not show signs of hammering on the handle as this causes sharp edges and weakens the handle.
