While well designed, they do break at the cut in the shaft. These are nice clean and ready to replace that broken safety in your gun or to have a spare when the need arises. Original factory WWII production, proofs may vary, they were made a number of places. As you can see the blueing is still very good. We have lots of other small parts for the MG-34 and barrels too, from blasters to really nice ones..
