The two solid cutters are tenon cutters for sure. The adjustable one? I just don't know. Looks more like a chuck to hold and spin something, but then I can't see it too clearly.

The pointer is a tool I need. I am having to rough out with a drawknife freehand

  Here are the two other common styles of tenon cutter, and what they do.
  Both need new blades. I am working on it.
I need some tool steel 1" wide and about 1/8+" thick and at least 4" long,
if you see any scraps laying around............(he begged)

Oh I just grabbed a stick of firewood off the ground, for testing. :)

Looks more like for cutting threads...?

took me a minute to understand this

threads, like pipe? nope not sturdy enough

wood..? OH!!!

like broomhandle threads...

or legs into the bottom of a table  threads

See...you should have bought all those broken chisels at the yard sale ;P

Yes...threaded dowls were very popular for a while, one of the glueless type of  joints

I Don't know that I have seen one with multiple blades tho....

The pointer is a neat tool, is actually in the fun realm to use.   Scott, for your new blade steel, use an old lawn mower blade, the price is right.

I have a thread cutter for wood, much more modern though.

It only has one v-shaped blade to cut the thread.

It cuts threads for push brooms, oaint sticks, etc.

Yep, #4 is a pointer.  It's kinda hard to make out #2, but it doesn't look like any adjustable I've ever seen.  Those look like one or the other of the two Scott posted.

Also once referred to as hollow augers..which they sort of are...an insideout drill bit...

1873 catalog...lots of sizes....
