Cutting plate

Cutting plate with removable spiral spring from Climbing Technology

The stitcher plate is an older belay device when climbing .

The original stitch plate - also called stitch brake - was developed by Fritz Sticht († 1988), a Franconian climber. He first presented them to the public in 1967 and had them marketed by Salewa from 1969 . She was the first mechanical cable brake and thus the successor of the carabiner brake designated Abseiltechnik . Because this old technology was from the time before the screw carabiners and had to be laboriously threaded with four normal carabiners , the stitch brake was a step forward. The device was safer and simpler, and for this reason it was very popular with mountain guides. After putting in the 1970s, two fatal climbing accident had occurred as a backup device in conjunction with the Sticht brake (each with Sturzzug on stand down), she came across much of Europe out of use, especially as the UIAA 1973 by Werner Munter around 1970 learned Munter hitch assurance as Recommended backup method. The cutting plate remained in use in England and the USA and formed the basis for the later development of the tube . The renaissance of the puncture brake in the form of the Magic Plate began when more and more stands were equipped with secure bolts ; because with fixed point belay it has the advantage that the rope pinches itself when securing one or two second climbers.

There are different versions of the cutting plate, but they all have in common that a plate is provided with two parallel slots several centimeters long. The bays of the single or half and twin ropes are threaded through one or both slots and secured against slipping back with a screw carabiner.

Instead of the needle plate, tubes (e.g. Reversos or ATCs ), which can be seen as a further development, are used today and the needle plate is no longer of any importance.
