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.

Thanks for all the ideas. I have a mini mill. The head tilts so I can
use a conventional end mill to cut these notches. I had a d'oh moment
and this very simple solution didn't occur to me until several of you
pointed it out.

Yes, these are going to be thumb rests/grips on the tang of a razor. I
do not want to machine them fully, but I want the spacing to be
absolutely regular, so I am just going to start them with the end mill.
The finished notches will be shaped with needle files and such.

Thanks again, guys.
