A shear-like cutting device comprises a first elongate blade 10 having a generally convex work- engaging-cutting edge 15 and an elongate handle 20, a second elongate blade 12 having a generally convex work-engaging- cutting edge 19 and an elongate handle 22, and a pivot 14 linking them together. In their closing stroke, the blades 10, 12 are swingable toward each other and their cutting edges 15, 19 oppose each other in facing relationship with the defined included angle between the blades at any point of their intersection having value of the order of 17 DEG +/- 3 DEG . The combined included angles of the bevels of the cutting edges of the blades 10, 12 is not less than 80 DEG and not more than 120 DEG . <IMAGE> |
