Looks like an angle grinder with twin 6 1/8" carbide blades rotating in
opposite directions. Cuts all kinds of material from aluminum, copper,
steel, wood to plastic. Cuts thin sheets, tubings, rebars without kickback
and without burs. Doesn't seem like the blade, at $50 for the set, will
last too long. Its proprietary so if Sears stop making those blades you
are dead in the water. Any opinions?

With you observations, buy one and try it out. If you like it, buy spare
blades now.
