Always good to have a weed puller in your toolshed. A stand-up puller, specifically, that operates as a lever, allowing it to first grab deeply and then through a rotation of the handle it pulls out quite a bit of the root system. A lifesaver if you have a rain garden which is really just a synonym for weed garden.
I've never used a bad one, although I wouldn't class any of them as anything stellar. All of them have looked like a snake's twisted tongue.
Using them depends on the delicate combination and application of brute force and technique. If your technique and brute force is up to spec, a crowbar works as a makeshift weed puller.
