This Forge de Laguiole corkscrew features a handle crafted from genuine Karelian Birch, a rare and highly sought-after wood sourced from the forests of Northern Europe. Also known as "Masur Birch," this material is famous for its extraordinary "marbled" figure, which features dark, wavy streaks and speckled "flames" set against a pale, golden-honey background. This unique pattern is a natural phenomenon, making every handle a one-of-a-kind work of art that is as durable as it is beautiful.
