A support recess 14 is formed, and a plastic mounting body 15 is formed separately from the opposed inner edge portion 12, and a pair of bars 16 are formed separately from the mounting body 15. . Each rod 16 is formed by bending a metal wire having a circular cross section into a U-shape, and has two tearing projections 18 that are continuous with each other at a bent portion 17. With the rods 16 fitted in the grooves 19 formed in the mounting body 15, the mounting body 15 is fitted into the support recess 14, and each of the rods 16 is inserted between the mounting body 15 and the support recess 14. A rod 16 is sandwiched and supported. The tearing projections 18 of the rods 16 protrude from the mounting body 15 in a cantilever manner, and are juxtaposed with a gap 20 therebetween.

When the scissors pieces 1 and 2 are closed, the arcuate concave surface 15 of the mounting body 15 on one of the opposed inner edges 12 is located between the opposed inner edges 12 and 13 of the gripping portions 10 and 11.
A hole 21 is formed between the hole a and the arcuate concave surface 13a of the other opposing inner edge 13. In this opening 21, each of the tear projections 18 protrudes toward the other opposing inner edge 13, and is located between the tip 18 a of each of the tear projections 18 and the arc-shaped concave surface 13 a of the other opposing inner edge 13. An avoidance hole 22 is formed which is continuous with the gap 20 between the tearing projections 18.

The axes of the tearing projections 18 extend linearly in parallel with each other, and the outer diameter D of each tearing projection 18 is set smaller than the gap G in the gap 20 between the tearing projections 18. , All the outer diameters D and all the intervals G are set to substantially the same dimensions. Assumed straight line 18b connecting the tip 18a of each tearing projection 18
Extends substantially along an assumed plane Q including the opening and closing movement direction P, and extends substantially along an assumed plane R orthogonal to the assumed plane Q including the opening and closing movement direction P. In addition, the assumed straight line 18b connecting the tip portions 18a of the tearing projections 18 is an opening 21 formed when the scissors pieces 1 and 2 are closed, and the distance W between the concave surfaces 13a and 15a (with respect to the axis of the tearing projections 18). Near the middle of the distance between the biconcave surfaces 13a and 15a in the parallel direction and the distance between the biconcave surfaces 13a and 15a in the direction orthogonal to the assumed plane R)
It slightly approaches the concave surface 13a and passes through the opening / closing center line 3a of both scissors pieces 1 and 2.

Incidentally, the outer diameter D of each tearing projection 18 is about 0.9 mm in diameter, the interval G in each gap 20 is about 3.6 mm, and the distance between the axial centers of each tearing projection 18 (G
+ D) is about 4.5 mm, and the maximum distance W between the two concave surfaces 13a and 15a is set according to the general outer diameter of the green onion.

After inserting the pair of scissors pieces 1 and 2 into the closed state as shown in FIG. 2 after inserting between the concave surfaces 13a of the opposed inner edge 13 of the portion 11, as shown in FIGS. In the opening 21 between the parts 10 and 11, each tearing projection 18 is hardly inserted into a bar 26 (for example, green onion). Next, when the whole scissors are moved in the longitudinal direction of the bar 26 (for example, green onion), the bar 26 (for example, green onion) is torn vertically by each tearing projection 18. If necessary, the same operation is performed a desired number of times by changing the position of the bar 26 (for example, green onion) with respect to each tearing projection 18. Therefore, the bar 26 (for example, green onion) is split into a plurality of pieces 2
It becomes 7.

Thereafter, when the end of the strip 27 is applied to the positioning portion 24 of the cutting length adjusting body 23 and the strip 27 is cut by the two blades 4 and 5, the strip 27 is cut from the strip 27.
