Which hammer?

Hi, I work at the pretzel place and I need a tool.

Sure, what kind of tool?

The pretzels keep getting stuck in the oven and I need a hammer to bang them loose.

I see.  Right over here is our selection of hammers.

Wow, there are a lot.

Let me know if you need any more help.

OK.  Which hammer would you recommend for banging on the side of a pretzel oven?
