Okay, so we don't really know what this is called. It looks like a spikey saw that feels really good when you rub your scalp with it, so we're gonna take a chance and go with "saw of spikes." But it doesn't even need to be called anything, because its mystery just adds to its degree of awesomeness and how much we want it. Which is a lot.

Don't you get goosebumps just looking at it? The spikes are obviously rubber, and can probably buff out even the meanest of headaches. And from the number of Tumblrs the "saw of spikes" is on, it hardly matters it looks like a torture device.
