I've been going through some buckets of tooling I've accumulated, and here are
a couple things I haven't been able to ID:

First one is about 3" long, steel, has rosewood inserts on either side. Two
edges are beveled but not sharp, the other two are flat with a small groove
milled down the middles.

Second is also steel, about 5" long. Some of the holes are threaded, some
aren't. The two tube sections on either end are held on with headless screws
from the other side.

Anyone?
