I've used the HF blades with mixed success. Some are sharp and stay that way for quite some time and some are duds right out of the package. I prefer 60mm blades, so have purchased from E-Bay: http://www.ebay.com/itm/231230080631...%3AMEBIDX%3AIT
The same seller also has the 45mm blades for a good price. So far I've only used one of the blades, but it seems to be holding up well. And when it gets dull I'll use the TueCut sharpener I have to extend the life.

Maybe I got a bad sharpener. I did exactly as you say. and took the edge completely off and would not even cut paper. It is trash as far as I am concerned and will send them my review. I will just continue to buy blades and trying some off the wall cheap ones that will be here Monday. Harbor Freight won't deliver to a PO Box so have to find out if they use UPS or USPS. If it is postal service then I won't use them

The blade sharpener will not take out nicks in blades, only sharpen a dull blade. And remember if you sharpen a sharp blade it will never get dull. I think the date on my last blade change was sometime last year. I sharpen it right before cutting a lot of fabric and sometimes will stop and sharpen it if I'm cutting a lot. Rotary blades from HF are hit and miss in fabric rotary cutters. Some okay, some crappy. If used in the cutter made for carpet and used to cut carpet they work just fine like they are suppose to.

I have the Tru sharperner and love it. Haven't bought new blades in over a year, I just do as the above quilter stated she did and its like a new blade.

Or you could order a 10 pack of Olfa brand (45mm) blades fro Handcocks of Paducah for $33-34.
They are the *right* blades for your cutter and mats, last appropriately long, and are shipped in a little plastic carrier where they can retain their lightly oiled state until they are used. Been using them for years.

Didn't really like them.

I use these blades. Once in a while there is a dud and you need to toss it but overall a really good deal. I use them in all different kinds of rotary blade cutters.

I didn't have any luck with the Harbor Freight blades. First pack I opened had two bad blades and the 2nd pack had another. I gave up at that point. I just buy the fiskars or olfa blades when I have a coupon. I've read a lot of negative reviews about that sharpener. I was thinking about getting one until I saw those (I think at Nancy's Notions).

I tend to find the best deals on Amazon. Then again, I have a 28mm rotary cutter. I get them (including shipping) for 5 for $11. They are Olfa brand blades. Tried an off-brand once & they got bent before they dulled. Very frustrating.

I will let you know. I have bought the carpet blades from H.Feight. I was ok with them at 1st. But after useing them I eventually got disappointed. I would say buy 1 pkg. And check them out. I have a lady friend, who buy's them on occassion. And likes them.
