I recently picked up a Leatherman 300 Super Tool EOD while visiting Portland, Oregon. Leatherman has an outlet store and I couldn't resist when I found this military version made for those who defuse things exponentially more dangerous than the occasional stream side disagreement. Sure a fly fisherman may not have a need for a C4 spike (maybe use it to tie nail knots?) but why quibble over details. The full featured multitool weighs in at 9.6 ounces and its comfort grip handle contains 19 different tools. It retails for $109 but is available at Amazon.com at various lesser prices.
