Longzon has just unveiled the zForge Electric Rolling Knife Sharpener, a first-of-its-kind gadget that promises to take the elbow grease—and guesswork—out of keeping your blades razor-sharp. Rolling industrial-grade diamond and ceramic discs across your knife’s edge, this countertop tool lets you dial in any angle between 10° and 25°, so you can sharpen everything from delicate paring knives to hefty cleavers with a single touch.
Under the hood, a low-speed electric motor spins four easy-swap discs: coarse 360# and 600# diamonds to knock out nicks, followed by 3000# and 6000# ceramic stones to polish your edge to surgical precision. A magnetic angle block holds your blade steady, and the entire system handles knives as narrow as 15 mm or wider than 35 mm—no special adapters required.
Whether Dad’s flipping burgers, carving roasts or prepping for a camping trip, this sharpener aims to keep every blade performing like new—no professional skills necessary.
