I do a lot of cutting with my HF blades and have never had a problem..seems like some do and some don`t..I will continue using them..they last much longer for me then the popular brand name blades..

That is a shame. You should return them. Maybe it was just a bad batch.

I haven't had good luck either.

Have been using Harbor Freight blades, excusively, for over 2 years. Excellent product. I buy them a dozen packages at a time. I just wish I could get them in the 60mm size. But, 45mm will do!

I tried thos Harbor Freight blades too and they were awful, than goodness I had only brought two blades.
You would think since they would cut carpet, that cotton fabric would be a cinch. Not so.

Me too. They are so cheap if I get one or two bad ones ( which I havenn't yet) it won't be a big deal. If you get a bunch that are bad it must be a bad batch. I am sure you could retun them.

My expierience with them was the same. I tried many and none would
cut. I will never buy them again.

I've tried several packages I bought here in Kentucky - they were terrible. My sister tried several she bought in South Carolina - they were terrible. Some people swear by them........me......at swear AT them!! LOL

Sorry you got a bad set of blades. I've used them for several years and so far have only had one package with a nick in the blade. I suggest taking them back, they should give you another package in their place.

Just another thought--what cutter are you using? I use the Martelli cutter and they work like a charm with that cutter.
