O Galoots
I have three planes that take double-edged razor blades, from two makers
in two designs, neither of which has been shown yet. There is some
discussion of them in this link
http://www.rcgroups.com/forums/showthread.php?t including a further link
to instructions on how to make your own out of wood, and about a third
of the way down there is a bunch of photos of different types. Mine are
a curved-sided Little Giant (I agree with someone in the link, this is
best of the lot, or at least the best I have handled) and two Wilkros.
The blades of the Wilkros stick out to the sides and cut your fingers
when you try to hold them (just the sides of the blades, not the edges,
but that is enough) so I suspect that fifty or eighty years ago razor
blades were narrower (had shorter edges, I mean... I mean, the long
dimension was shorter).
All mine are bare, now rather oxidized, aluminum. I've also seen the
Little Giant with a thin blue coating, more like anodization than
paint. They aren't uncommon in hand binderies, bought with the idea of
using them to pare leather, almost always ending up in the box of
totally useless junk. The problem is that there is no way to adjust the
depth of cut. I do know one good binder who used one for paring leather
for a while, but eventually she learned to sharpen and shifted to a
spokeshave. They must have been popular, though, because there are so
many around, and a lot of the modelmakers on the linked thread clearly
rely on them.
