These 100 per cent titanium attachments are exceedingly light — just 0.4 ounces — and fit all spread, wide spread, close spread, and semi-spread collars. When they aren’t keeping your collar points perky, these stays can be used as a half-Phillips screwdriver, slotted screwdriver, thread cutter and bottle opener. A pair retails for $US30 at Uncommon Goods. [Uncommon Goods via Better Living Through Design]
