An amazing dual mechanism that engages automatically the ratchet engages when the branch is thicker, when thinner the secateur stays in (standard) single cut mode. It couldnt be simpler! 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 from a standard oil can prior to use. Easily sharpened when necessary, use Darlacs award winning sharpener DP100F or 2 in 1 Tungsten and diamond DP102. To open the pruner, simply squeeze the handles together and slide the catch back.
