Do brass hammers chip?

I posted the following question few days ago but didn't get a satisfying answer:

I was installing a snow plow and needed to hammer a bolt through an opening. I grabbed my deadblow hammer (rubber on one end, brass on the other) for the job. Hitting with brass end, a chip from the hammer flew into my eye. Immeditate pain. I stayed at work to complete my shift and went home. Pain was worsening, so my wife took me to the ER. It was determined that the metal shard had torn through the cornea, iris, pupil, and was embedded between the lens and retina. Surgery was performed to stitch together the laceration where metal penetrated the eye to prevent infection. Antibiotics were injected into the eye as well. A second surgery is planned to remove the metal shard, replace the lens with a synthetic one, and remove the cataract that had formed immediately after the incident. The status of my vision at this time remains unknown. Regardless, a scar will remain, the effect of which on my vision will only be known with time. I have been ordered to remain off work for one week, and my ability to work effectively in the future is yet another unknown.

After all of this, I can’t help but think, should the hammer have chipped?

Moreover, on the hammer itself it states “wear safety goggles.” Do you guys wear safety goggles when you want to hammer something?

I have used hammers all my life. I feel like I was tricked. I would like to hear from you, to know for sure if this is just a stupid mistake on my part, or if I should take things further, so at least no one else gets hurt like this. I believe that this hammer should have never crossed the border from China.

The warning to wear goggles was written orange on orange. Secondly, I noticed it only when I examined the hammer closely after the accident.

I had the second surgery Monday. It lasted 2Hrs instead of 1/2 an Hour. The Doctor was surprised to find out that the piece of brass was as big as a fingernail...The intrusion had destroyed the eye and the artificial lens could not be placed where it was supposed to go. A transplant will be necessary for a recovery.

I said I feel like I was tricked because I have used hammers in my life and I have never thought that this one would chip on me. A hammer shouldn't chip.

Thank you all.
