A multitool is not what you carry when there is imminent need to use the tools on it (that?s where the real full sized tools come in) it?s just in case you have a use for it. So it may be feasible to leave the tool in a safe place.
BTW: Is there a thing like substitute envy? After all a lot of people envy me for having the substitute when they don?t. <img src="/images/graemlins/blush.gif" alt="" />
