I am sure Brookstone can answer your question. I lived across the river from them when their corporate office and showroom was in Peterborough, NH. After they went to dollar store junk they moved to Manhattan, KS. Years ago they were noted for having rare hard to find tools and that is how they built their reputation.
During the 1980's most of their hand tools had handles like the one you show. I still have and use a set of their shave hooks as well as a dowel thread cutter. Tap and die set for wooden dowels.
If you send them a picture I believe they would be glad to help you.
Thank you for your help. I appreciate it.
possibly wood carving/sculpture tools.

I would sooner think this is a tapered peg hole reamer. They were used by both carpenters and also plumbers. Once again I think Brookstone can solve your mystery.
Thank you for your comment.
I think you have a "bowling ball bevel knife".

Another one with a better working description.

I can say with reasonable confidence this is a Babbitt Bearing Scraper. Not all that long ago, before the present level of precision bearing manufacturing, most automotive and almost all large industrial motors and engines used babbitt sleeve bearings which were poured/cast to a close but still approximate size. A skilled machinist would then use a babbitt scraper and a compound called Prussian Blue to final-fit the (soft babbitt) bearing to the machine shaft. It was a delicate trial and error affair requiring tedious trial fitting and removal of material (the babbitt) until the clearances were near perfect. Some industrial engines still use this method of bearing to shaft fitting as babbitt is the only material that will meet the requirements of the machinery.
I disagree, as I own, and have used bearing scrapers several times over the years. They have 2 edges, with a 1/2 round backside, where as the bevel scraper has 3 blades. Here is what you may be thinking of in the link below.

Yeah, this is a machinist or bearing scraper, you can still buy these from McMaster - Carr supply check it out. I use one of these almost daily.
Take a gander at these examples of babbitt scrapers:
