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.

That looks like what I have. I'm squeezing the dickens on the
handles, finally punches, knuckles bang adjacent sheet metal :-(

That link at roper whitney is for the light duty punches. Go to the pull
down labeled punching and select medium duty for the next step up in
punching capability for the same hand pressure. Go the next step and look
at a #10 or #12, I got a #12 on ebay a few years back for $50, does 7 tons
of force with less muscle than you used to bust your knuckles on the little
one :-).

I love to cook with wine. Sometimes I even put it in the food.
