Hi Terry, all,

Couple of years ago I bought a jigsaw blade design for cutting
glass, it's made with grain of carbide weld to a steel blade.
Over the years I use it to cut many hard material with success.
It's suppose to be use dry but a little cutting fluid never
hurt... I never try it on SS but I cut a large piece of harden
chrome vanadium with success and the blade is like new not bad
for a $ 5.00 blade. I don't know if it's avaleble anymore?

Cheers,

Luc
