Handle material: Recycled and shredded bank cards (composite) Liners and bolsters: stainless steel Blade steel: corrosion-resistant 12C27 And now for the real story behind this knife: Some people call it the “knife of tears”. Not because of the blade – but because of what’s in the handle. Real bank cards were cut up, shredded, and pressed into a new material. Cards from purchases you were proud of. And from one or two decisions you’d rather not talk about. Plastic becomes handle material. Regret turns into a Laguiole. Upcycling doesn’t get much more honest than this. There’s only one comforting thought: This card can no longer be swiped – but at least now it cuts properly.
