Holme's Perforator

4.99

John Pocock Holmes (d. 1858) of London incorporated a double crossover joint so that the blades are opened by squeezing the handles together and hence with a much improved mechanical advantage.  Holmes designed the tip such that the perforating point was on one bade only, while the opposite blade was truncated.
