Get yourself a variety of magnets and the small tools you use the most around your shop.  If the tool is inexpensive, get several, such as pencils, marking knives, push sticks, wrenches. If necessary, cut a recess hole in the tool using a Forster bit. Glue (or tape) a magnet in the tool and then place it near the power tools where the gadget would be most useful.

I have a half-dozen pencils around my shop, and I attach them to my band saw, tool chest, table saw, etc. Whenever I need one, there’s one nearby, and it’s easy to “put away” a pencil or knife without placing it on a flat surface where it might disappear.

Think about the power tools that always need some small tool, and make one dedicated for the purpose. Power tools have lots of steel surfaces, and make a great holder for small devices.

I really recommend having a push stick attached to the side of your table saw. It’s always available, even when I remove or add a sled. I can grab it in seconds, and my arm never goes near the blade. And the side of my saw is always available. You never want to have to hunt for a push stick in an emergency. The stick is always in the same spot.

p.s. Don’t use too strong a magnet. You don’t want the stick to move unexpectantly.
