Amputation Saw (1823-1829)
Amputation saws were curved and looked almost like a machete until the early 1800s, when these shorter, lighter saws were invented to slice through human meat far easier. That’s the good news. The bad news is that few surgeons bothered to wash their instruments between operations. So even if you survived the unspeakable agony of having a limb sawn off, chances were good that the resultant infection would kill you anyway.
