Help ID these knifes?

[auto.pilot]

These three knifes were in the bottom of a box that came along with a metal lathe I just purchased. The seller told me that they were for cleaning threads, but I have my doubts. One of the blades is curved and pointed, one is triangular and the other looks like a wood carving knife. Any thoughts?

Thanks in advance.

Two I see as a debur knife and a burnishing tool. The third just looks like a usable blade. Since they appear to be a set, I can't be sure. Wax or pattern carving tools?

Small wood turners chisels?
I have something similar, but slightly larger, from my Dads old wood lathe stuff.
