I like to get all up in my snuggie. Get a little weird.

Atlatal

Candles

Well, of course, the greatest human invention...

Toilet paper.

As a user of threaded fasteners, the inclined plane.

Recently made some jam. Was really impressed by how low tech the process was. Just cook some fruits, separate the roughage and branches and seeds, etc. Add sugar and cook it again. I believe you also have to add pectin if the fruit you’re turning into jam doesn’t have a lot of it.

Then bottle the stuff and enjoy it with bread for a long long time!

Knipex Cobras. It's like being able to pinch anything with a force of about ten tons per square inch, they're indispensable

Stools

Exercising equipment. Jump rope, dumbels, pullup bars, rowing thingie and such.

Using a brush to paint my house as opposed to an hvlp setup

Sleeping pad shnozzle bags (pump sacks).

Hands. They’re freaking awesome and allow you to do lots of things.

I have a crowbar that I named Art. I like to compare my crowbar to a piece of art, it's a masterpiece of engineering. So many uses for the humble crowbar, such a simple and powerful piece of equipment. I love the way it feels in my hand, I love the way I can stash it anywhere easily and keep it handy and secret. The Crowbar is Art, and I study the Art of the Crowbar.
