So this looks very interesting if a bit expensive...
 

An auto sharpening rotary cutter that is motorized. It says it will cut fabric up to an inch in depth...I wonder how this would do with strip piecing...http://www.dharmatrading.com/html/en...ign=newsletter

no reviews on the site but has any one bought this and if so how does it relate to quilting?

Looks like it might be handy for cutting strips for instance, but way out of my budget...

And I thought $70 bucks for the Gingher rotary cutter was expensive! I'd definitely have to see a demo before I'd spring for that one!

I'd definitely have to see a video on how it works.

This looks like the cutting equipment used in a sewing factory. I wouldn't want to use it in a home setting. Anyway one miss cut and you have 100 mistakes all at once. LOL

Can't figure out how it works, but think that BellaBoo is right, one slip and you've ruined a lot of fabric.

Did you see that it weighs 6 lbs!!! That's quite hefty. I imagine it is for industrial use.

I was in a quilt shop in Tennessee a couple of months ago and they used one similiar to this to cut yardage. The owner said she got it at a trade show a few years back and it cost about $300. She said that they had figured out the cost of the mats and rotary blades they were going thru doing it the old way with a rotary cutter and that they have actually saved money by buying it. It was snazzy to see it in operation!

My problem would be how to keep it straight? It's like an new and improved version of the old electric scissors.

I can see it being beneficial for cutting yardage, or for kits, but not for any closely measured cuts. It looks to me like the fabric must go between the bottom plate and the blade. I don't see how you could use a ruler or template. I would have loved that, though, when I worked in a fabric store when I was a teen!
