Hi, I am an airline pilot and an active paper modeler. I was thinking it would be really cool to be able to build on the road. The only problem is, I don't know if security (TSA) will let an exacto knife through? I know that small scissors are ok but I think an exacto knife would be maybe too hard to get through. Any one have any ideas on what alternative building tools I could use to get through security? I know this is an odd question, but my layovers are sometimes 20 hours or more and I am dying to build!
