I read several of the posts here about the carpet cutting blades available at Harbor Freight (HF) for a fraction of the cost of replacement rotary blades sold in the fabric & craft stores.

I wasn't 100% sure my old blade was dull but once in a while I noticed it didn't cut as well it had in the past.

Off I went to HF. Lucky me, the blades were on sale for $1.49! Wow, I better get a few! At home I open the package to find not one but TWO blades! Wow, what a deal! Two blades for $1.49!

First few cuts are perfect but after a few passes of cutting with it, I'm here to say "you get what you pay for". It appears that the blade isn't round. I can feel it while the blade is rolling and now I'm getting way more uncut areas than I ever got with my former blade.

Last night I put my "old" blade back on and it cuts like butter compared to the HF carpet cutting blade.

I could have saved my time, gas and money using a coupon and getting the correct blade in the first place. I'm sure these blades would cut carpet like butter but I'm just not satisfied with the way they cut fabric.

Hope this info helps someone thinking about using carpet cutting blades.
