it might not be the knife. I think you got a bad batch of foam board. next time if you get this kind of problem before you bend the foamboard put some packing tape on the outside of the wing and your wing will not come apart on the front. if you ever get FB that is kind of mushy grab a piece of coarse sandpaper and make the knife blade kind of jagged this will cut the paper on top cut nicely. have fun.crappy Amazon box cutter and Xacto but mostly crappy box cutter.
