I try to use the metal cutting blades from lennox now. they stay together, last quite a while and don't get smaller as they wear out. lennox metal max. for the recip I try to find the ones I used to use as a firefighter doing vehicle extrication cutting the cars apart to get victims out after a car wreck. they were hilti or lennox fire and rescue blades. that with a spray bottle of water/dish soap mix to cool the blade and also help lubricate. Diablo carbide-tipped metal cutting reciprocating blade is a winner too, especially for the advanced steel used in newer cars, boron etc.

Way ahead of you. Those fiber discs bounce off the face shield all the time. It sucks wearing a welding jacket when it's hot out, but it's better than getting stitches.
