Kai Combination Whetstone 400/1000 Grit

Kai Combination Whetstone – Precision sharpening stone for razor-sharp blades

The Kai combination whetstone is a manual sharpening stone with two grits (400 and 1000). The coarse 400 grit side is for preliminary sharpening and repairing dull or damaged blades, while the fine 1000 grit side refines the edge for everyday use. The stone is traditionally used with water and is suitable for kitchen knives, pocket knives, and other blade tools.

• Two grits in one stone: 400 grit side for coarse sharpening, 1000 grit side for fine sharpening – ideal for complete knife maintenance.
• Manual operation without electricity: precise and gentle sharpening with full control over the sharpening angle.
• Generous dimensions of 25.2 x 9.4 x 5.0 cm provide ample working surface for various blade lengths.
• Versatile: suitable for kitchen knives, hunting knives, pocket knives, and scissors.
• Includes 24-month manufacturer warranty for long-term reliability.
