This sharpener has a very hard and durable Tunsten Carbide blade and can be used to sharpen secateurs, shears, long handled loppers and other pruning tools. Once you use this sharpener you will never go back to your sharpening stone.
Instructions: Place the sharpener against the blade at right angles to the handle. Angle the sharpener to the existing bevel on the blade. With firm pressure drag the edge along the full length of the blade, repeat several times.
On completion, unscrew the oiler pad from bottom of the sharpener and rub over the blade for protection against rusting.
