I'm not sure if there is a more official name for it but 'pointy french' is the one I go with.
Or you can draw the lines more round, to get heart shaped tips (there's a lot more going on with my nails here in this pic but ignore that).
If you want to fancy it up, make small dots in a metallic shade along the line.
Use a thick varnish with good coverage that is not too runn. Make the small dots with a toothpick, hairpin or needle for application.
The deluxe version would be small rhinestones, but I leave it to the salon for that.
