Horsley's skull saw, nickel-plated with stainless steel blade, c.1930, by Krohne and Sesemann.
The saw was used to cut open the skull and access the brain. It was invented by Sir Victor Horsley (1857-1916), an English surgeon and physiologist who pioneered the discipline of neurosurgery in the late 1800s. It has a nickel plated handle and a stainless steel blade. The handle is especially moulded to fit into the surgeon’s hand. The name of the makers, Krohne & Sesemann, is punched on to the blade.
