The common spokeshave has not changed much in over a century. The main types can be subdivided several ways but they are essentially, high or low angle with various shapes to the foot plate. I find this tool a great help when making bows, handles, or other spindle-shaped things. A flat shave will take you a long way but I get great use out of a rockered-style (convex front-to-back) for creating the complex shape of a bow handle.
These examples are from the very early 20th century and are all probably still in use from that era. I still have a boxwood low angle shave from my great-grandfather. The steel is remarkable.
Preindustrial Craftsmanship 
I have twenty or so, not even counting the ones I’ve given away. Kids can work with the small wooden shaves on a shaving horse without risk, they’re as safe as a safety razor. Never pass one up if the price is reasonable and there’s any blade left. Boxwood is best by far, beech is common, birch and maple were both used as well.
I woke up this morning wondering how a smith was able to forge those tangs into a perfect right angle with a sharp outside corner, and keep the tangs parallel in two planes. Have you noticed the Roman numerals in both blade and stock?
I’ll look for Roman numerals today!
