Nice find. You can split off the opposite side from the knot all the way to the end if you want to try to make a couple 52" bows. Maybe a bend through the handle? It might have deep splits on the ends though from not being sealed. Too bad the reflex doesn't go the other way. If it were my log I'd probably cut it to billet length too. But, when I cut lengths for billets I go more like 40" or even a little more instead of 36", that leaves room for a 4" splice and some checking. Do seal those ends to stop further checking, especially the end where you cut off the knot.
Good luck,
George
