Lansky Diamond Sharpening Hone Coarse SI4019

The Lansky Diamond Sharpening Hone Coarse is built for those who demand serious edge repair and aggressive sharpening performance. Made to handle the toughest, most wear-resistant tool steels, this coarse diamond hone delivers fast, effective results where traditional sharpeners fall short. Whether you're restoring a severely dulled edge or prepping a blade for finer grit refinement, this 120 grit hone is up to the challenge.

Constructed with a durable, coarse diamond abrasive surface, this hone is engineered for speed and efficiency. Diamond is the hardest known sharpening material, and it excels at grinding and reshaping blades quickly—especially those made from modern steels like S30V, M390, and other high-performance alloys. If you're working with steels that chew up basic stones, this is the tool that bites back and gets the job done.

This hone is designed for use with the Lansky Sharpening System and attaches easily to the included guide rod. That means precise, repeatable angles every time, even when dealing with aggressive stock removal. The hone’s ergonomic, color-coded housing gives you a secure, comfortable grip, and the diamond surface holds up through repeated sharpening sessions without loading up or wearing down prematurely.

Whether you're a knife maker, field operator, or just someone who likes their edges crisp and clean, the Lansky Coarse Diamond Hone brings pro-level performance into your workshop or pack. It's the go-to choice for revitalizing dull blades and establishing a reliable working edge in minimal time.

Proudly made in the USA, this hone reflects Lansky’s dedication to craftsmanship and functionality. When you reach for it, you're not just sharpening a blade—you're investing in a tool that's built to last and designed to perform under pressure. Order it today from SMKW!
