I have a single-action sheet metal punch, punches holes from 3/32" to
9/32". I think I got it at Harbor Freight.

Whilst adding some extra holes to the frame of this work-bench I am
building I royally busted up my knuckles.

Is there a multi-action device out there that has real pressure
multiplication?

Dunno about the ones HFright sells, but the genuine USA-made
Roper-Whitney punches are pretty decent:-

They come in different sizes.
