Facom Pliers for Plastic Cable Ties (455B) - for all tie widths 2.4-9mm . Strong simple tool with good demultiplication. Long stroke for fast action. Tails cut separately to desired length. Replaceable blade and spring. Red resin finish. Overall length = 190mm.

Note- I've looked at some of the cheaper competitors coming out of China (click on photos to enlarge). The Facom 455B is considerably heavier due to a heavier gauge steel and has a real coil spring in the handle instead of a cheap torsion spring.
