Thank you for viewing! There are various shapes of springs, but this cutter uses a spiral spring. I, for one, am captivated by this aesthetic beauty and would want to own it just for that reason. Judging from the shape of the blade, it seems the user is a specialist in wire systems. Thank you for your consideration.
