The pointed one is 3 1/4" long and 3/4" round. The larger one is 3" long and 1 1/2" round.
Thanks,

The pointy one looks like a lathe center and the one with the set screw looks like part of an extension for making auger bits longer.

I don't think the pointy one is a lathe center. A lathe center would have a Morse taper where the knurling is. Unfortunately I don't know what it might be.

Lathe centers are 60 degrees, that looks like 90, and it has been hammered on end and knurled. I would guess a center punch to locate drilled hole. Not sure about the other with set screw. Since it is knurled and has many holes must be for turning or twisting something.

The one with the thumb may be a drift, designed to hold a piece of drill rod.
The pointy one looks kinda wide to be just a center punch, perhaps for driving out a piston with a center already in the middle or such...

FWIW it kinda looks like a tool that could be used for dowel joinery.

I take that back... It looks similar to a packer drill attachment, included in a late-teens Starrett pressed-steel socket set.
Fig. 230 shows the unmarked drill attachment shown with the early Starrett No. 443-A socket set. The drill attachment consists of a 5/8-drive adapter threaded to screw into the knurled body, and the drive end of the adapter has a tapered square opening (not shown) for holding the drive stud of an older-style drill bit.
The overall length is 5.1 inches in the retracted position. The finish is plain steel.
