When it rains, it pours. In the last month I have learned about three new Neva Clog staplers. The appearance of the P-50 connects a model number with the US2033599 patent drawing. At first, I was a bit puzzled by its appearance, the spring button that pushes up through the anvil plate. Fortunately, the patent drawing explains its purpose. The anvil of the P-50 is designed solely to pin and the button prevents the staple from bending up in the middle, producing a easily removable staple. The design seems almost limiting but I am sure with knowledge of its intended application, it makes perfect sense. In any case, I am only too pleased to share another chapter of the Neva Clog story.
