Karsten International 3-stage manual knife sharpener — a compact sharpening system to restore kitchen knives quickly.

Stage 1: tungsten steel for very dull blades — restores basic edge.
Stage 2: diamond rod to align and smooth the edge.
Stage 3: ceramic rod for polishing and fine tuning.
Ergonomic handle and non-slip base for stable countertop use.
Draw the blade through the correct slot 3–5 times from heel to tip.
For metal-bladed knives only; easy to clean and store.

Safety: keep fingers behind the guard — sharp blade. Keep away from children.
