I doubt that any experienced turner would have any problem using a file as a turning tool, but there are reasons that it is actively discouraged.
File scrappers were common in schools until the early eighties. They were used a lot due to poor finances and teachers with no real experience of turning.
There was an incident involving a kid at a school, who hit the wood before the tool rest. The gap between the tool rest and the wood was vast, and the tool shattered causing multiple injuries.
Modified tools were immediately banned!
Old files can conceal micro fractures in the steel, usually by kids hitting them together etc, which they have a tendency to do all the time!
I've had to take several modern hammers out of circulation for chipping, after they have been used on the original 1940's anvil in our school.
Work hardening seems a difficult process to explain to both teachers and students these days.
The old carving knife I use as a thin parting tool is brilliant, but I can't use it in school.
I'm sure this new tool will give you many years of service.
