Dor, based on the discussions here, I think a farriers rasp should be your next purchase. You can use one for any and every self bow you make from this point forward. I use mine all the time. And when you get ready for a draw knife, I'd suggest shopping for a good, older used one. Check the big auction site, local antique shops, flee markets etc. A lot of the old draw knives are better quality than the new ones......and less expensive. I looked at the Flexcut draw knife you referred to and I think I would pass on that one. Hope this helps.
