Are you using these in your round cutter?

There is only round cutters as far as I know....Do you have another kind??

Right you are.So,that's a yes?

Didn't someone on another thread say that these blades chew up the mats faster because they are sharper than regular rotary cutter blades?

Got to get me some of these and try them.

The one I have in my rotary cutter has cut fabric for three quilts , queen size , still sharp.

I replaced my blade yesterday with one of them and man was it sharp. The ladies at my little sewing group gave me the money to go and buy a bunch for them on Tuesday next week when I get back over there.
One lady had a cutter, I didn't pay attention to the name of it, but the original blade hole had like a 3 sided circle, I don't know how to describe it it looked a bit like 3 flower petals. Anyways the blade worked on it too. So that doesn't matter.

I love mine. I buy all they have every time I go by there. LOL

I went the totally opposite direction and invested in a Gingher rotary cutter and blades. Talk about super sharp!! At almost 11 bucks per blade I'll only buy them at 50% off at Jo-Ann's!!
