Beam stick
The beam stick is the main tool of the emitter .
description
Usually the beam stick is forged from an octagonal iron , with at least the ends being hardened. The original shape (also called Bündner Strahlstock ) is bent at right angles at the top with a flat chisel-like end, whereas the lower end is usually made like a pointed chisel . When searching for minerals, this tool is used in particular as a hoist and crowbar to break down rock and open crystal fissures (English pocket ). In addition, depending on the type, the jet stick is also used as an extended chisel , hoe, extended arm, brooder, walking aid, etc.
The original Bündner beam stick was further developed and today there are different types and shapes. In English one speaks of pry bar , whereby the Münsinger beam stick type is also called pocket robber after John Sinkankas . The slightly angled ends allow a more favorable leverage effect to be achieved when used as a hoist . In addition to the mentioned jet stick types, there are also composite jet sticks, whereby two ends are inserted and screwed into a tube-like middle part.
