This age old design is now available in a size geared to flameworking. The blades of these shears are each shaped with a large V in them. When the shears are closed onto hot, pliable glass, up to 1″ in diameter, they form a square, or diamond, around the glass, contacting it in four spots. Squeeze the shears closed a little, and the glass uniformly constricts. Close the shears all the way and the glass is cut clean.These heavy duty large diamond shears have long lasting durability and excellent craftsmanship. They are ideal for cutting and shaping hot glass. Total length is 9.5″, blade length is 50mm and blade thickness is 5mm.
