Document Type and Number:
Japanese Patent JP3459678
Kind Code:

Abstract:
PURPOSE: To efficiently dig a groove by a small force of scraping a cutter in a short time by forming the cutter in a shape of substantially L shape as seen from a cutter edge.
CONSTITUTION: A grip 3 is grasped by one hand, and a body 2 near a bent part 2a is grasped by the other hand. First, an edge 12b of a first cutter 12 is brought into contact with a surface of a foamed light concrete material (ALC slab) A while providing an attitude of a normally using state. A groove digging tool 1 is pulled in a groove digging direction X by both the hands thereby to remove a material of the slab A by the cutter 12, and grooves A1, A2 are gradually dug deeply. In this case, a second cutter 14 is brought into contact with the side of the groove A1 thereby to prevent lateral deflection of the cutter 12, thereby preventing distortions of the grooves A1, A2.
