With blades just like the standard bronze cup jack but with a very unique handle style first made by Jim Moore that he named the “Squareback”.
the squareback handle creates a wider bend that forces the blades to be more parallel when held open. They are incredibly nice for opening straight sided thin vessels that are either cylindrical or conical.
Why bronze?
Theres a bunch of reasons why I chose to make jacks with bronze blades. Firstly, bronze is softer than steel and gives you a very smooth experience when working hot glass with them.
Bronze does not chill glass like steel does. The result of this is that you gain working time, which means you might be able to make a piece in less reheats.
Because the bronze blades do not cool the glass like steel does, your jack lines will be less prone to creating chill marks, which is the number one cause of wear on jack blades. With this logic one can assume that a pair of bronze jacks could outlast a pair of steel jacks if used with care. Also, bronze does not rust !
Bronze is not for everything and should not replace steel for times when force is needed, or used for prolonged use on very thick hot glass.
