What sort of end mill do I need to mill a series of V-grooves in the

The steel is annealed D2, S30V, or ATS-34, from .125" to .250" thick (a
knife blade), and I want to make a series of regularly spaced V-grooves
laterally along the edge or spine, like this:

The angle does not really matter as I will be finishing these grooves
by hand with needle files. My objective is regular spacing with a
V-shaped notch or groove.

Sorry to be so dense but I am still learning some of the terminology
for these things.

I would tape a thin plate to the vise jaw at the proper angle to guide
the blade and make a spring stop from an old hacksaw blade to index on
the tooth just cut. If the blade and tang is too long for the vise,
attach the angled guide to a thick upright plate and reclamp the blade
after cutting each tooth. An endmill for 90 degrees or a dovetail
cutter for 60 in a vertical mill should work well enough, especially
if you saw out most of the notch first to reduce the workload on the
cutter.
