Close, but farriers rasps usually have individual rasp teeth, occasionally float cut teeth, that cut in one direction only. More important they are usually U shaped, with the sides acting as guides to keep the rasp on the tooth.
This is a shoe makers peg shave or float - it cuts in both directions, used for trimming the wooden pegs that protrude through the sole into the inside of the shoe... They are also found with rasp teeth (especially in France, where they were also used by sabotiers to remove rough spots inside the wood clogs (sabots)...)..
