Anyone ever used a tack hammer for aid climbing?

I'm going through a deceased friend's aid climbing gear and found a 5oz tack hammer. Does anyone know what you might use that for in aid climbing?

Thanks!

Looks like this...

Would be nice to carry on clean walls for cleaning stubborn nuts

Like. Fer what?

I could be completely off base here, but possibly for copper heads/circle heads or some such in tight seams/cracks. Are those not "mashed" in?

Any aid climbers out there able to answer this question?

For aluminum and copper heads me thinks.

For Kneecapping slow parties infront of you at belay ledges!

You're gonna want a heavier hammer for placing heads and pins. This isn't a full on wall hammer

I use a small ball peen hammer to clean nuts on some walls
