The cutting edge is Blue Paper Steel, a high-carbon tool steel prized for its exceptionally fine grain structure, which allows it to be honed to a keener edge than O1, A2, or PM-V11, while also holding that edge for longer. Laminating it to a mild-steel body solves the brittleness issue common with hard steels, resulting in a blade that is tough, durable, and far less prone to chipping.\u003c\/p\u003e\n\u003cp\u003eThe mild-steel backing also means there is less ultra-hard steel to remove during sharpening — so honing is quicker than you'd expect given the hardness, and the blade works with virtually any sharpening medium: water stones, oil stones, diamond plates, and sandpaper all produce excellent results.\u003c\/p\u003e\n\u003cp\u003eDesigned to fit Stanley-style No. 4 and No. 5 hand planes, this blade is compatible with a wide range of vintage models (Stanley, Bedrock, Record) as well as modern makers including Lie-Nielsen, Lee Valley Veritas, and WoodRiver.
