What do you folks do?

Do you still have bottles with corks that need an opening tool?
Punch or machine some opening tools (that attach to key-ring) as
give-aways. I have one in my keyring I got some 15+ years ago,
cnc-machined from some hardened aluminium. Could simply mill one
from empty ammo cardridge.

Use a custom die to form some simple candle-holders from plate,
could also use something like spot-welding to assemble holder piece
(for finger). Especially girls/women might be interested for
making their traditional night-light-candle-holder.

If sparks are allowed and a little excitement, make simple
throwing knives and throw them to a target after finishing each..
Would be easy with (plasma-cutter and) belt-grinder, for example.
Throwing knife doesn't need to be too fancy from material
point of view, so easy to make so it lasts a few times of throwing.
Wow-factor of 2 with sparks AND throwing knives for all males.
