Just wondering if anyone has ever boughten a DualSaw. They have been advertising them on TV here for a while now. I am not sure if it’s a woodworking saw, but it looks great for construction. It is like a small circular saw except that it has two blades that rotate in opposite directions and its supposed to cut wood, metal, and stone without changing blades or binding. They show it cutting plastic, wood, rebar, steel sheets etc. Looks like a great idea if it works.

I can’t speak for the Dual Saw, but I bought the similar version from Sears. I lent it to a friend so I’m not sure of the model number. Earlier this year I had to trash a very large metal desk.. Not expecting it to be great I used it to cut the desk in half to get it out of the house. I was amazed. It cut it in half in about 20 minutes and as I remember it was really easy. I hope this helps.

Hi Wayne. I saw an ad for one at Sears too. They must have carbide blades because they even go through steel. The counter-rotating blades keep them from grabbing or pulling when it goes from hard to soft material.
I had seen one used years ago and it was a pretty effective saw!.

Wayne, here is a link to a video from Discovery Channel – the PitchMen show: You might be able to find some more.
I did see one of their shows and the guy (the inventor) cut a car in two in a few minutes. While he was cutting the show producers realized there was still some gas left in the pipes and they started worrying about fire. The guy didn’t want to stop and there was no fire. Apparently it makes no sparks.

Radu…Thanks for the link. I think they were using part of it on the TV commercial I was watching. Looks like a good tool. I was thinking it would be nice for cutting rebar and other metal things around the house.

I’ve been pondering one of these dual saws as a way to quickly and roughly cut sheet goods because it’s light and can easily do plunge cuts, according to the commercials. I’ve seen a couple of other brands of these types of saws, but haven’t had one of the original dual saws in my hands.

User reviews I’ve read are pretty black and white; people either love it, or they hate it. If they hate it, it’s mostly because the motor burned out on them too quickly. MY guess, and it’s only a guess, is that folks have trouble keeping the blades lubricated. On all of these saws, there’s a port in the blade cover for wax sticks that keep the two blades lubricated as they spin opposite to each other. If they aren’t lubricated, I can see how that would burn out the motor…

I’ve seen the prices range from $99 to $129, and that’s still just a little too much to spend as an experiment, so I’m going to have to wait until I actually have “spare” cash 8^)

I’d really be interested to hear from any other LJ’s who have experience with the saw!

Rebar dull’s blades really fast. I wouldn’t cut it with anything but an abrasive wheel.

Have your say...
