History
John Weiss was an Austrian born Master Cutler
who established a London- based instrument
manufacturing business in 1787. Under William
IV John Weiss was appointed “Razor Maker to
the King” and many of the old instruments feature
the Royal Arms on the handles. “John Weiss …
entered into his manufacturing the ideas and
requests of the physicians ordering and he
became extremely skilled by so doing.” Excerpt
from Abstract written by Werner Teichmann.
