{"type":"firestarter.listing","listing":{"id":"lst_9u7xukXc","product_name":"Mercator Brass Pocket Knife with Leather Strap","category":"Pocket Knives","description":"A refined take on a historic classic. This Mercator knife reimagines its traditional black steel casing in solid brass, giving the piece a more elevated presence. The handle is finished with the iconic embossed Otter Messer design—subtle, distinctive, and timeless.\nDespite its elegant appearance, this knife remains durable, and built for everyday reliability. It’s a tool meant to be used, carried, and appreciated over time.\nBecause brass is a softer metal, slight tool marks from the manufacturing process may be visible. These are not imperfections, but natural characteristics that make each knife uniquely its own.","images":["https://cdn.shopify.com/s/files/1/0720/5824/1345/files/mercator-brass-pocket-knife-1.jpg?v=1697474470","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/mercator-brass-pocket-knife-2a.jpg?v=1697474473"],"price":98,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:22.898Z"},"share_url":"https://firestarter.network/l/lst_9u7xukXc","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
