The side cutter is of very good quality and has cut in my previous application without problems 2mm nails. Although the cutting takes optically some damage because the black coating flakes off, but a look through the magnifying glass shows no damage to the blade. Anders, as shown in the figure, the side cutter does not return spring (have Amazon 'correct picture' on notified). The hinge is so smooth that the side cutter opens again, if you hold it only on a handle. Anyone looking for a side cutter of this size, in my opinion, can be accessed safely.
