Judith --

There are sketches/diagrams in Ashburners lab manual, and probably in some
of Marting Heisenberg's papers (or you could talk to him directly, I
suppose). They're easy to have made, which is what we did, but I don't
know of a company offhand that makes them. Each one is just a block of
Teflon with a trough cut through it, and two holes drilled on each side
for screws (with washers) to hold the razor blades in place. Just be sure
the holes will allow you to place the blade edges close enough together!
