Look close and you can see a lot of chatter. Try giving it a lick with a decent sized boring bar. Use a tiny bit of radius on the tip and hone the edge razor sharp with a small hard stone. It should come out pretty smooth, probably good enough. A strip of 120 grit emery wrapped around something-other-than-your-finger would polish it a bit further.
Oh, to be clear. Try a HSS bit.
