Lansky Afiladores Master's Edge MEDGE1

The MEDGE1 supports three pre-set sharpening angles: 17°, 20°, and 25°. These angles are molded into the base and clearly labeled, so you always sharpen at a consistent, repeatable bevel without any measurement or setup. Use 17° for fillet and fine slicing knives, 20° for butcher, paring, slicing, and skinning knives, and 25° for hunting, camping, utility, and chef's knives.

Yes, the Lansky Master's Edge MEDGE1 is specifically designed to sharpen serrated blades. The included medium triangular ceramic rod features three distinct radii that fit into most common serration patterns. Work each serration individually by drawing it along the appropriate radius of the triangular rod to restore the edge. The same triangular rod also works on awls and fish hooks, making it a versatile tool well beyond straight-edge kitchen and field knives.

Ceramic rod sharpeners use high-alumina abrasive rods to gently remove metal and refine a blade edge, making them ideal for regular maintenance and fine polishing work. Diamond sharpeners use industrial diamonds bonded to a surface and cut far more aggressively, which makes them better suited for severely dull or chipped blades that need significant metal removal quickly. For knives that are sharpened regularly and not badly damaged, a ceramic rod system like the Lansky Master's Edge MEDGE1 produces a finer, smoother edge and is gentler on blade steel over repeated use.

A ceramic rod sharpener gives you more control and is much gentler on your blades than a pull-through sharpener. Pull-through sharpeners are fast and simple but use fixed abrasive wheels or carbide slots that remove more metal per pass and can leave a rougher edge over time. The Lansky Master's Edge MEDGE1 lets you choose from three different angles to match your specific blade geometry and progress through medium then fine grit at your own pace. For quality kitchen knives, hunting blades, or any edge you want to protect long-term, a ceramic rod system is the better choice.

Clean the ceramic rods by rotating them in the guide holes periodically to expose fresh abrasive surface as dark metal deposits accumulate. When the entire circumference is coated, scrub the rods with kitchen cleanser or use a Lansky Eraser Block (model LERAS, sold separately) to remove the metal filings and restore full sharpening efficiency. The high-alumina ceramic material does not wear down from normal use or cleaning, so the rods last indefinitely with proper maintenance. Avoid dropping the rods on hard surfaces, as ceramic can crack on impact.
