Tell us about yourself!
So, the TSA rules say pliers and screwdrivers are allowed, as well as scissors with blade less than 4". Knives are not allowed, or ice picks. The rules also say "Evenif an item is generally permitted, it may be ...not allowed through the checkpoint if it triggers an alarm during the screeningprocess, appears to have been tampered with, or poses other security concern". So just the fact that the tool is modified can stop it. Your "TSA compliant" looks like an effort to camouflage an obviously tampered-with tool and actually makes it more suspicious. Better to just to remove the knife and pick like items. You will still have a very useful multitool without em.
Leatherman has a whole lineup of travel friendly multitools (http://www.leatherman.com/travel-friendly) and the screeners are by now most likely quite familiar with them and knew that a Squirt was not one of them.
