A stamped knife is relatively inexpensive. Each knife is cut from a sheet of metal and then machined. Victorinox and most Global knives are stamped. Global knife construction is unique. The handles are hollow.
Stamped knives are lightweight.
One advantage of Global knives is their light weight, which reduces fatigue when used for an extended period of time. The forging randomizes the metal particles for a slightly tougher knife. It also permits the differing thicknesses of metal which is necessary for a heavy raised bolster between the knife handle and knife blade. Forged knives have more metal than stamped knives and thus are heavier. The forging process enables extra metal proportioning to give the knife perfect balance.
