2642 might be good for cutting rubber tubing at 90 degrees. You'd need
a tool like a checker with a dowel glued through the center at right
angles. The diameter of the dowel should be the inside diameter of the
tubing and small enough to go through the small end of the slot.
If you put the dowel through the slot from the far side, holding the
checker against the unseen face of the tool should keep the dowel
perpendicular to the blade.
With the dowel coming through the big end of the slot, slide the tubing
on from the near side. Depending on the position of the blade relative
to the slot, pushing the checker to the small end could cause the blade
to cut through the tubing to the dowel. Slide the checker back to the
big end, rotate it a few degrees, and repeat. You could end up with the
tubing cut off evenly at 90 degrees.
2641 I've seen some gas valves that used a slot wrench with a shape
like these, but I suspect these are for something else.

2642, we can barely see the edges of the razor blade. Looks like the center
part turns, and cuts off something that sticks through the tear drop shaped
holes. Not sure why there is a flat base, so it looks like it can sit on a
desk or shelf when not used.

2642 could be used to trim the ends of plastic optical fiber to make a
smooth end before connecting. Like these tools:
It also might be used as a wire stripper, or to remove the sheething from
small coax cable.
I like the suggestion. For stripping the jacket -- and the
braided shielding from coax cables -- at a guess in the size range from
RG-174 (a little over 1/8" diameter) up through perhaps RG-59 (close to
5/16" diameter). It would need a larger opening to handle RG-8 and
The two similar sides could be set up so one cuts deep enough to
go through both the jacket and the shield, and the other only through
the shield -- but setting the projection of the razor blade would be
tricky at best.
It is common to have a specific length of center conductor and
insulation projecting, then another shorter length of braided shielding
before getting to the fully jacketed remainder of the cable. But I
don't see anything serving as a settable depth stop for each cut.

2642) Looks like a microtome (thin slicing tool for samples to go
under a microscope. In this case, it would be for stems of
foliage which would be placed through one of the teardrop
holes, the blade holder would be rotated to force the sample
into the narrow end of the teardrop, and then slice it.
Then you would move the sample a little farther into the
teardrop and repeat, producing a thin slice of the stem to be
mounted on a glass slide and studied under the microscope.
It might also be a tool for preparing stems for splicing.
2643) 6" long seems rather small for this tool, unless it is perhaps
6" from blade to hammer head.
Otherwise, it looks like a hammer, hatchet, and nail puller.
If the 6" is overall length -- head to handle, perhaps it is
used for model making.
