Electric Mini Belt Sander, 3 in 1 Bench Grinder, Knife Sharpener for Kitchen Blades

Built to last on the bench: stainless steel construction resists rust through years of use as a knife sharpener, bench grinder, and metal polisher
A cluttered workbench with three separate machines for sharpening, grinding, and polishing eats up desktop space few home shops can spare. This 3 in (7.6 cm) 1 electric mini belt sander squeezes a knife sharpener, a grinding wheel, and a cloth buffing wheel into one palm-sized tool that saves real desktop space. It handles grinding, polishing, and sharpening jobs faster, smoother, and more precisely, and it's built for knife making, woodworking, metalworking, and jewelry DIY alike. Fine sharpening work that once meant swapping tools now happens on a single machine.
Underneath, an all-copper motor with high torque runs 4000 to 9000 RPM in dual-direction rotation, and the 15-degree tilt built into this bench grinder locks in the sharpening angle so a blade comes out even every time. As a woodworking sander it also smooths edges on cabinet parts and small furniture pieces, not just metal, and as a kitchen knife sharpener it's sized to sit on a counter instead of a full workbench. Swap the grinding wheel for the polishing wheel and this same rotary sander becomes a jewelry-finishing tool in seconds — a benchtop sander, a mini grinder, and a small sander for the corner of any shop, all in one compact body, and with additional accessories it goes further still, taking on drilling and polishing tasks beyond its 3-in-1 sharpening set.
