Work shorts, knee pads, chain saw sharpener, socket sets, ratchet spanners, self propelled petrol lawn mower, etc etc Ironically, according to the Mrs I only ever buy anything when I've inadvertantly forgotten my wallet so put it down as ' general shopping '.
SWMBO on the otherhand buys loads of kitchen shite that, like the churros maker, never gets used and is resigned to the bottom of the pantry.
