Powerful Ratchet and single cut mechanism. Simply swing the lever over with one hand to switch from a powerful ratchet to a simple cut. Tests have shown Ratchet pruners to require up to 30% less pressure than conventional pruners, as the Ratchet mechanism multiplies pressure. The loop handle serves to protect the hand and also gives greater control. The integral oil wipe allows simple lubrication of the blade. Load oil wipe froma standard oil can prior to use. Easily sharpened when necessary.
