As long as you don’t find jewellery a tad effete, you might say, choose this eg for your wedding ring, (if you are a gear junkie anyway)…Will multi-tools get any smaller than this? Danger swallowing warning! (I should probably recommend that THIS ring is not to be used for any other ‘playful’ purposes – the risk of self harm is just too great). You CAN imagine though, it might get you out of some tight spots, say if you are captured by terrorists, or find your arm stuck between two rocks & etc: https://www.etsy.com/au/listing/115928701/the-man-ring-titanium-utility-ring
