Fine detail work? The Tantos are fighting knives. I’m not sure what work you are using them for.
That is a common misconception, possibly due to marketing and possibly due to the name which confuses people into thinking it is the same thing as a Japanese short sword.
I've used my Recon Tanto since 1997 for many things but I've never used it on a person.
I've also carried my Emerson CQC-7BW EDC since 2002 and also use it as a tool.
The secondary edge and secondary point are useful tools.
I'd agree that the Magnum Tantos are more fighters than utility knives, especially the MT12.
It is a similar thing with Bowies, some are mainly fighting knives and some are mainly outdoors knives and some are a bit of both. I'd say the Trailmaster is a good balance of the various uses of a Bowie while the Laredo and Natchez are more in the fighting category.
Some of this "action" related marketing applies to other knives as well.
I've seen numerous knives that look like typical utility knives, often without any guard, marketed as "fighters."
