Taiwan design outfit Mininch presents a stainless steel writing instrument that conceals a second purpose. Simply remove the pen’s barrel, undo the safety lock, and you’ve got a tiny pair of scissors that goes anywhere. Given their size, they should be TSA-friendly too.
Nikken Cutlery sells a line of scissors that look like Japanese swords. They have blades lined with hamon, handles that look like wrapped hilts and scabbards for storage. The top-of-the-line model is based on the sword of the warlord Oda Nobunaga and costs over $300.
