A surgical blade and method for performing a one-pass wedge osteotomy. The blade includes a body portion, having a cutting tip on a first end for initially cutting into the bone； a cutting slope comprising multiple rows of cutting teeth at multiple planes to resect bone as it enters, leaving a wedge osteotomy； a shaft of a predetermined length and width for supporting the cutting slope； and a saw attachment base on a second end of the blade for engaging a base of a saw to cause the blade to oscillate and perform the wedge osteotomy.
