I’ve had many part nippers over the years. Currently my favorite ones are the blue GodHand nippers. The $50 price was a major turn off but I’ve used them quite a bit. They do cut flush or very nearly cut flush dependingon alignment. Parts clean up is far less hassle. They have become a favorite tool.
They are definitely more for finesse than brute force. When there is a nasty sized sprue or big attachment point, its back to the Xuron’s which are excellent for the heavy duty plastic cutting.
