What Mike and the others said, I also am amazed you can bend that by just hitting, it's junk and could cause an accident, bin it.
What I don't agree with is a wood handled hammer, I haven't counted but have at least 20 to 30 hammers, some left over from my business where they were seriously abused by the lads and the 2 Estwings I kept are by miles the nicest to use imo, a 20 oz for general and 16 oz lighter work. Worth every penny and when things get back to normal the boot sales are the places to find them for just a few quid.
Both mine are well over 20 years old now and the 20 oz has been dropped from roofs, used as a delolition lever and knocked in 1000s of 4" nails.
