PROBLEM TO BE SOLVED: To provide a joint part processing implement which enables preparation of the respective angles of adjacent side ends of plaster boards to be the same substantially and putting of putty for sealing therebetween and also enables execution of work without hurting the hand of a worker, on the occasion when the putty is put for sealing for finish between the side ends of the plaster boards disposed adjacently to each other. SOLUTION: In the joint processing implement constituted of a base part 1 and a cutting part 2 at least, the cutting part 2 is formed of a semitubular member, and a notch hole is formed around the surface where the semitubular member of the cutting part 2 comes into contact with a material to be processed. An edge 4 is provided at the peripheral rim of the notch hole formed in the cutting part 2 and the side end in the longitudinal direction of the cutting part 2 is fixed to the base part 1 so that a cavity 5 extending to the opposite ends in the longitudinal direction of the cutting part 2 is provided between the cut part 2 and the base part 1. In this constitution, the edge 4 is so formed that it is slanted at a prescribed angle and projected outward from the cutting part 2. Moreover, the edge 4 provided at the peripheral rim of the notch hole formed in the cutting part 2 is made regulatable as to the amount of projection, according to the material to be processed.
