All depends for what you intend to use it cause different hammers have different purposes :) ...

seen on the Bazaar of Madurai, the man even didn't notice I was taking this photo, he noticed only after hearing the click of my camera.

The bazaar indeed a paradise for action-street photography, enjoy.

PS
I was lucky, no damage by a small motor accident, only the bike was reshaped a bit ... a drunken doctor was playing jallikattu on the road. Lucky I did not have a hammer with me :)!
