Acoustic Guitar Construction

I will be travelling on I-80 across Pennsylvania next week, and I frequently stop at Grizzly to wander the toy store. I noticed in their sale catalog that spokeshaves are discounted a bit. They offer two styles, flatbottomed and convex-bottomed. I am gathering tools to work on necks, and I'm curious if the Grizzly tools are good enough to use, and if so, will I have use for both shapes or one in particular?

Thanks, folks.

Can't speak for anyone else but I use a flat bottom and I use a Hock blade in my Stanley spokeshave. IMO, the blade type and sharpness are more important than the handle.

Getting a sharp edge on the curve spoke shave has been a problem for me -- its sits unused.

Thanks for the replies.
