Tama TMT9 Drum Multi Tool

It holds all the tools you would need for drums and more, it's very well built and solid and I love it, however, it's very big, it takes some room in a picket, like a swiss army knife really but bulkier. I kind of revert naturally to my small drum key, because even though it offers plethora of features, a square key is really all we need... Don't get me wrong, it's a very good product, I just don't use it as often as I'd hoped.
