This is a tool for use in model assembly. These nippers from the hobby masters at GodHand are made specially for cutting parts from plastic runners. They feature a thin, flat blade that will cut close to the sprue and lessen the chance of leaving nubs on your parts, and they can cut plastic up to 3mm thick. They're part of GodHand's "Craft Grip Series," which means they're even more comfortable than your standard nippers, and will cut without much strain on your hands. They're great for Gunpla, military kits, and more! Note: These cannot be used to cut metal.
