Why are these cutters made like this :
... rather than the simpler one-pin concept used in pliers and scissors?

There are arrow marks on those bolt heads. I was wondering why.Baluncore said:The two hinge bolts, closest to the cutters, are eccentric. To adjust the separation between the cutter jaws, the eccentrics can be rotated and then locked.
The free link between those eccentrics allows for some forward and backward movement of the jaws.
That is because the opposed V jaws progressively increase their contact with the material being cut. That material is initially deformed, then as the remaining section is reduced, is stretched beyond its ductile elongation limit. The jaws do not need a sharp edge, and need not meet, so long as the stretch of the bar exceeds the elongation limit.jrmichler said:It's easy to nick the wire, difficult to get a complete cut.
