Such results lead to second and even triple touch ups with more cutting, sanding and repair. You need a model kit nipper to precisely cut trees with the least amount of sheer. The One Pull Pro Precision Model Kit Nippers will do the job the first time, every time. For All grades and no grade gundam model kits; great for perfect grade, master grade, real grade and high grade kits. <br> Push spring up a little with fingers if pliers do not spring back after each cut; storage in case for long periods of time may have pushed spring a little out of alignment. </br>
