That doesn't make sense. What kind of carpenter has 2 hammers in his belt but no puller? Also, we are talking here about hammers in the aisle at the home store. While I personally wouldn't have a problem abusing a Vaughn or Eastwood, I'd be leery of those in the boxes on the bottom shelf.
That's one tool I won't buy at HF.
I carried two of three hammers in my back belt loop most of my time as a roofer. Depending on the job, I carried a 10 oz. AJC titanium shingle hatchet, Estwing 16 oz. finish, and a Estwing 22 oz. Shingle hatchet. I also worked as a residential framer for a couple years and usually had a finish and a framing hammer in my belt loop.
I usually had a flat bar on me, but frequently it wasn't the right shape/size/angle, and I'd have to use one hammer to drive the claw or hatchet of another in to something. I always had eye protection on, although I never chipped any of my hammers.
Striking two hammers together is a risk. Wearing improperly fitted eye protection is dumb. My everyday job as a roofer presented much riskier and more dangerous requirements than possibly lodging a small piece of steel in my skin. I stepped on hundreds of nails (I love having to climb through the dump bed full of tearoff), fell though dozens of rotted sections of roof, smashed my hands, got pieces of wire wheel in my arms, cut myself with knives/tools/tearoff, hit in the face when a bungee cord snapped, etc. Despite what an infinitely-expanding OSHA would like you to think, there are many workplaces that employees will always be at risk for a boo-boo. You could wear this:
, but you'll die of heat stroke or starvation from not making any squares (shinglers get paid by piece, not hours).
