The coarse side uses Orsa sandstone (120–200 grit)—a fossil-free sedimentary rock used for sharpening since the 1500s. Its slightly porous surface removes nicks and restores edge geometry. The fine side features rare Los slate (500–1000 grit), found only in one Swedish region and prized since the late 1800s. Its smooth, hard surface hones blades to an extremely sharp edge with excellent bite.\u003c\/p\u003e\n\u003cp\u003eBoth sides work with water to remove metal particles and maintain consistent abrasion. Together, they provide a complete blade sharpening tool in a single, portable tool.\u003c\/p\u003e\n\u003ch2\u003eSandstone Sharpening Stone | Blade Sharpening Tool for Axes and Carving Tools\u003c\/h2\u003e\n\u003cp\u003eThe rounded, ergonomic shape sits comfortably in hand, making it easy to follow existing bevels and grind angles when sharpening \u003ca title=\"Forestry Axes\" href=\"https:\/\/bloomist.mom\/collections\/forestry-axes\" target=\"_blank\"\u003eforestry axes\u003c\/a\u003e, knives, carving tools, and other hand blades. It arrives in a vegetable-tanned leather sheath from Tärnsjö Garveri with a strap for attaching to trousers or backpacks.

Start with the coarse side, using smooth, consistent strokes along the entire edge.

Repeat with lighter pressure to refine the edge. A burr will form on the opposite side, indicating metal removal.
