I prefer the Nicholson Farriers Handy Rasp. It doesn't have the pointed handle tang, but has a rubber covered beavertail type grip. It has rubber on both ends actually. It's shorter and thinner without the screw on handle and I find it more maneuverable, or 'handy', for lack of a better term.
There are a lot of good drawknife brands and styles out there and personal preferences on blade shape and angle, handle shape and angle, thickness, length and such are so subjective, we can't help you much there. I've got several from Ebay, but if you buy used, study them carefully. You want no pitting, good tight handles, and a good blade bevel that doesn't look like someone sharpened them with an angle grinder.
Card scrapers... mine are Sandvik, now Bahco. They're good. But there are others equally good. Dean Torges goes into detail on how to sharpen them in his book, Hunting the Osage Bow, and there are videos on youtube. It is certainly worth the little bit of time it takes to learn to sharpen them properly. I followed Dean's book and squared, honed, and rolled the burr on my first scraper on my first bow when I didn't know ANYthing about scrapers. Knives make dust, properly sharpened scrapers cut ribbons.
I also wouldn't want to make bows without my Nicholson #49, #50 and a few double cut files. I'd give up my Farriers rasps long before that would ever happen. I don't use farriers rasps that much, and on some bows I don't use them at all.
