[Pocket Size] The package includes 3 pieces of diamond knife sharpeners: 2 double-sided knife sharpeners (black and orange) and 1 sharpening pen for replacement. [Foldable & Safe] The tool sharpener is made of diamond, which is durable and long-lasting. The ABS plastic grip is comfortable and ergonomic, reducing hand fatigue. Its foldable design allows for convenient storage and portability while preventing accidental contact with the sharpening surface. [Double-Sided Sharpening] The coarse 400-grit side is ideal for quick edge repair, while the fine 600-grit side is designed for honing to refine the edge. No oil is required—dry or water-based sharpening is sufficient. [Retractable Sharpening Rod] The diamond-coated sharpening rod offers excellent wear resistance and precise sharpening performance for knives, fish hooks, and other small tools. It features an aluminum protective cover and a clip for secure pocket or gear attachment. [Portable & Versatile] This diamond knife sharpener is suitable for a variety of tools, including pocket knives, pruners, hedge shears, hatchets, scissors, and machetes. Its compact size makes it ideal for carrying in a pocket, backpack, camping kit, or toolbox. Color may vary slightly due to lighting and screen settings. Slight dimensional variation of ±1–3 cm may occur.
