An early outdoor knife, and ahead of its time, it was used to cut all manner of things, both on the field and in the forest. This started with the farmer's bread or tree branches, the scraping of barks for making fires or for cleaning the hooves of horses when they had stepped into something that had to be removed.\nIt has a very idiosyncratic form. The handle is rather angular, occasionally slightly coarse, and is made of untreated beech wood. The fixing spring, made of iron, which keeps the blade in place with the help of a snap-in hole. It is a simple, yet exceptional mechanism.","images":["https://cdn.shopify.com/s/files/1/0720/5824/1345/files/Robert-Herder-Traditional-Lierenaar-Pocket-Knife-Carbon-Steel.jpg?v=1697474396"],"price":78,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:22.952Z"},"share_url":"https://firestarter.network/l/lst_-iBz6qO7","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
