Save them, but not in a big drawer. Every time you need an Allen key for something specific, tape it to it or store it with the item. For example my dining room table has the Allen for the bolts it uses taped to the underside of the table. Something feels wobbly, easy fix. No need to hunt a specific key out of the tool box.

It lives with its brethren in a shoebox on a shelf in my garage. Every once in a while, I try to remove duplicates which I will eventually probably scrap.

I feel attacked.

Tossed in the kitchen drawer that has all the odds and ends in it.

I always lose them.

"Always two there are, no more no less. A master and an apprentice."

My dad does this, we have functional tools, he won't use them.

I had a neighbor that didn't have a job so would try to find creative ways to get money. He tried selling a drawer full of rusty Allen wrenches on Facebook for $100.

I don't think it sold...

I do the same, but with those keys that come with the phones. Well, I actually needed them in the end.

Lol Me

Buy Wera or another really nice HQ set of these and you'll never need another one again.

well, you should buy two sets, because you might lose one....

Best part is I don't even use them. I have a ton of nicer hex wrenches in multiple forms and just use them instead of what comes with the product.

Yet I keep the wrench they ship.
