Yes it can often take longer to work with hand tools, but hand tools still yield the best results. Hand tools do exactly what you make them do, and a cut surface is much better than a sanded one. First, a cut surface is incomparably smoother: a finely honed blade cuts the wood fibers; whereas sandpaper scratches the surface in gradually finer scratches, leaving a muddied appearance to anyone with an eye for fineness. Second, you can always get precisely the shape you want, in all its subtle varieties. And third, the graceful textures left by gently overlapping toolmarks add to the tactile enjoyment of the piece, as well as testifying to its authenticity.
