I'm thinking about next projects and am considering making a Krenov style hand plane. I already have a Stanley no. 5 as my only plane.
Taking that in to consideration, what would be the next most useful type of plane to have around (block, fore, jointer, smoother, grooving, etc)?
I will probably only be making small-ish scale things for the foreseeable future (let's say less than 4 feet in length).
