To the average person it’s just a gigantic, oversized nail, or a weapon of intimidation (who needs to carry a can of mace when you’ve got this up your sleeve, am I right?), but to me this is the perfect tool for making drainage holes in things that were not manufactured to function as plant pots.
A dremel or cordless drill, and a masonry bit is your best friend when it comes to making holes in terra cotta and ceramics, but a gigantic nail and a hammer is exactly what you need to effortlessly put holes into the bottom of recycled tin cans, metal buckets, busted watering cans, and creepy doll carriages.
Cost: $.89 brand new at my local hardware store. Or free if the roofing guys are slack and leave a bunch lying around where you could step on them and possibly develop tetanus. That’s how I acquired my previous giant nail. Fortunately, the part about stepping on the nail and developing tetanus is not true, but it COULD have happened.
