I'm trying to understand why it's so difficult to punch holes in bananas.

Perhaps the banana is there to keep cats away?

Patented by Mine SAFETY Company!

I believe it would have been much easier to read the narrative in the patent if it had been written my Mr. Temple himself rather than the attorney.

Must be a really tough banana. Maybe it's a GMO variety that's been engineered to not bruise in shipment.

Bet he had to shell out for the legals.

no legal worries in 42,i bet the oil field companys bought some, and the us military in ww2 and korea bought some too, never know when u might need a hole in some thing and no electric drill around either..

I wonder if with a bit of mod , this device would work with diesel or WD40

Would have liked to see the hole it made?

Good use of an old dining table also. I did the same in one of my sheds.

I would image it is just like the one next to where he made that shot.

This is something new to me I have not seen one of these
I have so meany questions :-)

This would be great for doing field work. I've used an electric hydraulic punch in the field, but a generator is needed and you have the hydraulic pump and hoses...

Its basically the same principle as the power shot nail gun for putting nails into concrete.

I wonder if one of these is still available to purchase?

I wonder if it even made a hole. I watched this one and another one on YouTube, should’ve removed the tool and showed the hole.
