Overkill but will work -;)

I've cut a few paddles (not canoe) with a simple metal cutting fine toothed blade by hand. Shaft wrapped with 1-2 wraps of masking tape before cutting. No jigs - just rest the shaft somewhere where it won't get scratched. After the cut, simply sand with a piece of sandpaper on a flat wood block to remove the half-millimeter or so that might be out of round.
Even if it is not perfectly cut, that part goes into the grip so a half millimeter or so imperfection does not matter in the least.
Of course, a jig will make it nearly perfect, but "good enough" in this case is sufficient as nothing is seen and there is no drawback to having a minor imprefection.
I've shortened a 2-piece carbon wing paddle paddle this way and just recently cut in half and reattached in the center a 1-piece bent-shaft white water paddle (to make it a 0 offset from whatever it was before). In both cases no jig was used and both worked to within 1/2 millimeter without trying too hard... Both now work better than new -;)
As for removing the grip, heat will help only if some glue that melts easy was used and will not work well if a good epoxy was used. If the grip is epoxied to the shaft, then heat will just do nothing or if too much heat - will weaken the shaft and the grip... In that case - scrape the short piece of shaft from inside the grip after cutting it off...
Also, if the grip on the Zav is anything like the carbon grip on my lughtweight Werner canoe paddle, then it is likely paper thin, filled with styrofoam, and very easy to damage - so don't squeze too hard and don't heat it up too much!
