In most of my work the next step after the drawknife, is the hand plane. [Why do we call them “hand planes” instead of just “planes”] NOT a planer! a plane.
[pet peeve: ebay people; a plane with a wood body is NOT a block plane! ALL block planes have iron bodies! you calling a coffin plane, a smooth plane, a foreplane, a block plane because it is made from a wooden block just makes you all look dumb!]
The working principles are the same no matter if you are using one with an iron body or a wood body or transitional or infill or European or Japanese or whatever!
The body of the plane rides on its sole, and holds the cutter at the right angle and at just the right amount of protrusion to make a thin slice of wood. leaving a smooth surface behind it.
keeping the blade still and in place is it’s entire purpose.
