Strange end mills

I found a few of those in some dull endmills that I was given. Discovered them when I was sharpening endmills. They sharped easy enough, but you can not "correct the grind" as someone suggested as the helix is off center. The sharpened ones seem to cut ok.
 
You can always grind them into V cutters and single point countersinks. You can always use them for practice.
