I'm still dubious of my ability to get this done in time, but I at least got a start on it today. During my short lived forging 'career' a couple of years ago, I forged out 3 blades and this was the last one I did. It was forged as a drop point but otherwise was pretty similar to Lorien's design A, so I did some reprofiling on it today and starting cleaning up the ricasso and tang. (The ricasso is shorter than Lorien's drawing, so I may tweak to profile a bit to make it flow better.)
Here's the blank so far along with my quickie cardboard cutout/drawing extrapolated from Lorien's posted pic. I hope I'm on the right track with this, Lorien; feel free to offer critiques if you feel that I've missed the boat on your design!
