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

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.

Assuming you are using something like a Bridgeport to cut the grooves, you
can either use an end mill, or a dove tail cutting end mill (if you don't
want to tilt the head 45 degrees), or an arbor with a V shaped radial cutter
like a heavy rotary saw blade. You can easily cut a groove and/or radius
with a radial cutter, without tiling the Mill's head.
