Call and prearrange with the airport to there rules, they might ask you to put the tools in the lower storage area, even if they say no, its always professional to ask, if you need them with you, depending on where you live you might be able to aquire a permit or such to present that might better your odds, its a tough call good luck buddy, but as shrub said hiding is the worst.
I mean you could aways bring a model car and put them in there with some paint brushs and paints NO HOBBY KNIVES!!

that might work as well, but i'd says ome sort of permit to carry or posses and inquiring before hand fully explaining them would be best.
Oh i also head of people mailing them to were they were going to avoid taking them on the plane all together, i think some people do this for defcon. Just some ideas.
