the file on the wave/charge is for wood on a side, metal on the diamond coated and it's also a metal saw. Not the best one you can find bet you can cut 3mm nails with it.The victorinox metal saw is more aggressive in my opinion. Mextreme: i already saw this accessory, but on the sell page, there was an advisory as it wasn't very strong as it wasn't melted , any feedback?
Super Tool 300 EOD has a blade exchanger that takes jigsaw blades, and comes with a metal saw (note: does not fit surge file or saw). Are you wiling to drop the coin for one, is the real question.
