The object of the present invention is to provide an angle setting tool (41, 21, 81, 31) for setting the blade section (64, 74) of a hand scaler (50) at a predetermined angle during sharpening of the scaler, and a hand scaler sharpening device (10, 80, 30) which has a relatively simple structure, is easy to operate and do maintenance, and reduces complexity in the sharpening operation. This object is achieved by a hand scaler sharpening device (10, 80, 30) including a sharpener main body (11) having a grind stone (13) provided for reciprocating motion, and an angle setting tool (41, 21, 81, 31) for setting the tip (74, 74) of a hand scaler (50) at one of a plurality of predetermined angles on the grind stone (13), wherein the angle setting tool (41, 21, 81, 31) has a plurality of inclined surfaces (22a, 23a, 24a 82a, 83a, 84a 33a, 33b, 33c) corresponding to the predetermined angles.
