Your best/worst innovative but completely incorrect usage of tools...

So... I just used my hot air rework gun to help defrost my freezer.
Unsurprisingly ice won. It doesn't matter if you hit that stuff with a hot air rework at 450*C or a full on flame thrower ice is self insulating.
All I could do was speed things up slightly, enough to get the top drawer out. Now I have to wait while my food defrosts slowly in the other fridge on full.

I semi regularly use sockets as receivers or pushers for impromptu press operations (press a 3D printer hot end out of the cooling block and into a socket or use a socket as a pusher to evenly press in a bearing).
If your freezer was self-defrosting (and the reason for the repair wasn't "because the heating element broke"), I've used the timer to run multiple back-to-back defrosting sessions to clear the freezer more completely of ice. It does take a long time with the heat gun (I used a paint-stripping sized heat gun and it still took a while-my task was "defrost so I could get in there and replace the failed elements")

Here's a good tip a mechanic showed me of how to get more leverage on a combination wrench.
Use it all the time in the land of rusty crap...
paulca:
Unfortunately it's not self defrosting. It does have a folded back door seal that leaks slightly so over months frost forms in the top drawer. Leave it too long and frost forms on all the drawer fronts and then frost pushes the door open. If you don't notice in side a day the whole freezer turns into an iceberg. After a day or so you eventually notice things in the fridge freezing as the compressor is all constantly trying to keep the open freezer frozen.
To make matters worse it has those clever grilled shelves where the cooling pipes run, so they get absolutely clogged in ice preventing the drawers from coming out.

I tried that once on a POS floorstand Whirlpool freezer (the heating element was fine and it took me a while to find out the temporizer relay was faulty). The hot air station (Aoyue 852A++) did not have anywhere near enough airflow to get things going. My wife's ultra-powerful hair drier was much more efficient.
Regarding the main topic, I have used knifes as flat screwdrivers, car batteries as doorstops, old soldering irons as drills (in plastic), rearview projector pens to draw PCB tracks (as etch-resistant), steel wool as bare PCB cleaner, lighters (or fire in general) to remove enamel from coil wires... You get creative when resources are scarce. :)
