Does anyone have this 5" Double Cut Saw SKU 68316? If so, what do you
think of it, especially for steel and aluminum? I have other devices
to cut each but it would be nice to have something like this if worth
a flip.

I know that are metal cutting circular saw blades but they are
expensive.

Thanks for any comments.

Is the Patent on the dual saw up? or did HF just rip them off?

Harbor Freight doesn't manufacture anything.

The patent could have expired, or the owner of the patent could have
licensed it to make more money.


Not sure but the "original" was an Australian design. We have two, one the
newer Craftsman unit with the larger motor and blades and the other is a
Duo-Saw. Both work well and the BIG benefit for the Fire Dept is that they
will cut through just about anything on a car without changing blades.
They also generated less heat and sparks so using them on vehicles is
safer than using a normal chop saw. You can take out a side window then
cut though the pillars and glass like butter. Less mess and safer because
the blades are smaller and more controlled than most other tools.They are
also a LOT lighter than most other cutting tools as well. Quieter as well.

You sound like the infomercial.
None of what you cite is necessarily due to the counterrotation claims. Why
would counterrotation reduce sparks?
It's the net pitch of the blade.
