3-Groove Ceramic Tungsten Blade Sharpener

Length: 21.5 cm, width: 5 cm, height: 5.6 cm. Constructed from three complementary materials: ceramic (corundum-based) for fine abrasion, tungsten steel for durable groove structure, and impact-modified plastic for shock absorption and grip. Three clearly differentiated sharpening paths: two wide coarse grooves (for rapid re-bevelling of nicked or rolled edges), and one narrow fine groove (for polishing and removing wire burrs). Base features four recessed non-slip rubber pads providing 360° stability. Smooth, seamless transitions between materials and surfaces prevent dirt traps and simplify cleaning. Designed exclusively for manual, dry sharpening of thin, straight-edged tools — no electricity, batteries, or consumables required.
