The Spokeshave is to the drawknife what the hand plane is to an adze or chisel… if you look at the blades of the older spokeshaves they even look like mini-drawknife blades.
A light touch holding between the first finger and the thumb and just using the rest of the fingers just touching the handles to help steer it. Use it while at the shaving horse or wherever it is handy to trim a little with this tiny plane…
you can buy used and refurbish them, or buy new iron bodied ones, or get a kit from either Dave’s Shaves or Veritas and make it yourself.
With the new iron ones be very careful, make sure the blade lays flat on the bed with no gap behind it! If it has a gap leave it/return it.
As with all tools there are many variations and they all have their place/purpose.
That big ebony one is great for shaping the outside curves on a Windsor chair seat. and the little one just above is made to take the inside curves on scrolls.
Start with one, get used to it, and only get another when you decide you really need it.
