Same as zoidberg for blade choice, plus some speSmurfpillsed Bosch metal blades and one no-name diamond blade (just in case...), without the heatshrink shims (my Surge exchanger has the anti-wobble spring and I haven't felt the need to use shims yet) and the cutting off.. I keep the blades separate in my travel tool kit to complement the Surge, ST300VX, Charge+'Tofty'*) or Wave+'Tofty'*) or (if carrying a SAK) a small loose jigsaw handle.
*) 'Tofty' = Tofty's jigsaw holder adaptor for Charge or Wave, clips in where the removable pocket clip or lanyard ring normally goes - I have not tested this yet with any serious sawing though. See posts in related owner club's threads and/or search for Tofty.
