Forget about rasps you won't need them as your shoulders will be as good as shaped for you to finish them use a spokeshave and or a drawknife
Ok best go for a 12" Drawknife older ones have better steel in them stay shaperer for long as well
Spokeshave go for an old cast iron one stanley, record
Also look for an old wooden plane [a bit lighter to use, so make sure it's isnt a heavy wood]
Smoothing plane and if you must a block plane.
Travishers - look for a convex spokeshave or a snell leather thingy people talk about. those Gandmtools ones take a lot of setup and sharpening...
You need something to sharpen your tools with as well
