Hi! I've flown from (and to) Israel twice so far with my rig. Once to Italy via Moscow (with Aeroflot), and once to Czech Republic (don't remember which airline). I took my rig with me on the plane both times (with Cypres, without the hook knife), and had no issues with it. I always carry the Cypres x-ray card with me, just in case :) Also, I used a RigSleeve the last time, which makes the rig slightly less conspicuous when carrying around, though it obviously does nothing with x-ray scans.
