The roto-lever, according to Coxeter, could be turned to set the scarificator by a child of six.
Thus it appears that the scarificator was invented between 1708 and 1719.
According to Bayfield, the blades of the scarificator were generally set at ¼″.
Unlike later attempts at improving cupping technology, the scarificator was almost universally adopted.
This special model of scarificator continued to be sold by Coxeter and Son (London) until late in the nineteenth century.
By 1780, illustrations in surgical works showed that the bottom of the scarificator was detachable.
For those skilled in the art of cupping, the torch, cups, and scarificator were more effective.
After each use, the scarificator was to be cleaned and greased by springing it through a piece of mutton fat.
Frequently a veterinary spring lancet or fleam is mistaken for a human lancet, or a scarificator for an instrument of venesection.
Furthermore, the scarificator was so constructed that when the spring was released only internal parts moved.
