{"type":"firestarter.listing","listing":{"id":"lst_US44_Zc9","product_name":"Rook Knife","category":"Daily Carry","description":" \n\nMore info\nThe culmination of more than two years of design and prototyping, The Rook Knife is the one we've always wanted and could never find – a thoroughly distilled construction that strips away the excess. Pocket knives have always possessed some familiar, gravitational power; from the time that we're old enough to understand their value as useful, beautiful, dangerous tools, they hold our imagination - beckoning to be picked up and used. The Rook Knife is a full-metal construction, slimmer than most folding knives, but with greater density and heft.\nThe updated Rook Knife now features a reversible wire-formed deep carry pocket clip.\nThe Tricolor version features a body that's half brass-half stainless, and a blade that's black PVD coated for a hint of tactical precision. A nod to the classic Craighill color/material palette, it's an unusual blend that works shockingly well. The brass side is left untreated and will develop a natural patina – the more you use it, the brighter it will stay. \nSpecifications\n\nBlade Length: 2.3 inches / 5.8 centimeters\nClosed Length: 3.2 inches / 8.1 centimeters\nOpen Length: 5.5 inches / 13.9 centimeters\n2.2 oz / 62 grams\nBlade Steel: 12C27\nBlade Type: Drop Point\nLock Type: Frame Lock\n\nPocket Clip: Reversible Wire-formed Deep Carry\n\n\nCare & Maintenance\nClean with mild detergent and warm water.\nDry thoroughly after cleaning.\nThe brass component will develop a natural patina over time — this is expected and adds to the character and story of the object.\nStore closed to protect the edge.\n","images":["https://cdn.shopify.com/s/files/1/1040/0808/files/2024_9_25_Craighill_1_e32c6f2f-559e-4031-a451-7ce04ef74fa8.jpg?v=1752071483","https://cdn.shopify.com/s/files/1/1040/0808/files/2024_9_25_Craighill_02_0f71bea6-3fe8-40ed-859f-131b9e3503f6.jpg?v=1752071483","https://cdn.shopify.com/s/files/1/1040/0808/files/2024_9_25_Craighill_03_8dc51aa5-17e4-476e-a6af-d2bdf2438173.jpg?v=1752071483","https://cdn.shopify.com/s/files/1/1040/0808/products/rook-stainless-LS-4x5.jpg?v=1763062619","https://cdn.shopify.com/s/files/1/1040/0808/files/rook-knife-stainless-closing-LS-4x5.jpg?v=1763062619","https://cdn.shopify.com/s/files/1/1040/0808/products/rook-knife-tricolor-4x5.jpg?v=1763062619","https://cdn.shopify.com/s/files/1/1040/0808/files/rook-tricolor-open-LS-4x5.jpg?v=1763062619","https://cdn.shopify.com/s/files/1/1040/0808/files/rook-tricolor-LS-4x5.jpg?v=1763062619"],"price":128,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:48.599Z"},"share_url":"https://firestarter.network/l/lst_US44_Zc9","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
