I havent had any troubles with them. One package I had bought one of the blades had a nick in it so I tossed it but only saw the nick after I tried to cut some fabric. So as I was putting it back into the packaging so that I could tape it up really good to put into the sharps container, stupid blade came through the cardboard and cut my thumb so be careful with them. But that is the only blade I have had trouble with.

the 1st couple of blades from Harbor Freight didn't cut so well. But I've had no problems withe the remaining blades I purchased.

Still using mine from months ago still sharp and cuts like butter!

I've had no problems!

My sister gave me some and they do not cut as easily and I have to push down way harder. I will not be using them when I run out. I have used several in the past few mths all dull and not so good.

I bought mine and put them where I knew where they would be and now I can't find them to try LOL

Ummm..... what's a p.i.f. squishy? :-)

Do you order these on line? you. Exactly what do I look for. I'd like to try these.

I ordered a dozen packages on line. The first blade of the first package had a nick in it. The second blade was absolutely great and I got a lot of use out of it.

Do you suppose the Harbor Freight blades work better with certain rotary cutters than others ? I have an Olfa cutter and have only used the Harbor Freight blade for a few cuts, but it worked fine. I will have to give it longer use before I really know if it cuts well.
