For whittling wood or keeping under your mattress like a little security guard, pocket knives are handy. The culmination of more than two years of design and prototyping, Craighill's Rook Knife is a frame lock folding knife with S35VN blade steel, a drop point blade, and a flipper mechanism for easy one-handed opening (be a Shark or a Jet). Constructed entirely from metal, it's slimmer than most folding knives, but with greater density and heft. The Stainless version is monochromatic and beautifully reflective, with the unified materiality highLighting the nuances of the overall form.
