Can you help me stop biting my nails?

Aside from smearing some of Grandma Guru’s homemade bitterant on your fingers – she calls it jam, but we all know the truth – Guru can’t stop you munching on your fingers. But an investment in pricey high-tech nail clippers might just fill you with enough buyer’s remorse to do the trick. Shell out £75, then, on the Khlip (khlip.com) – it collects your nail clippings, and moves the point of pressure to directly above your nail for the perfect cut. It’s also impeccably designed, to the point that house guests will want a go on your nail clippers. Which is a bit weird.
