Pliers for top leader reduction.

To avoid the top leader getting too long, you can use the Top-Stop pliers of Danish design, which makes specific cuts to the cambial ring of the leader.

These cuts typically reduce the length-growth of the leader by 30% and do so by reducing the sap flow to the terminal bud.

By reducing the leader length you achieve a more visually-pleasing, denser tree with less distance between the whorls.
