I have used these blades for a couple of years and love them. I had one that wasn't cutting right but for the price they are one is a few cents. Like many people said,they do stick together so you should check to see if you put two in. Hope the board tips have helped you. You should not put down all tips. Some tips work for us some don't!!

I've been using them in a Olfa cutter and a Fiskars and haven't had any problems at all. I just was over there last weekend and bought some more. Sorry to hear you had problems but you shouldn't discount everything said on QB just because you got a bad batch, I'm just sayin.

When I first tried the HF blades I couldn't get them to work either. All it would do was shred the fabric my sister in law had the same problem. I didn't give up and then I noticed that the blade wasn't turning. So then I loosened the tightening screw a bit and they work just fine. The only problem I have with the blades now is safely getting them out of the package. I hate the packaging

They work in my Olfa and cut just as well as the pricey ones.

I agree with -Quilter day-by-day, I have used the HF blades and got a bad blade also but the rest of the packs I have tried were great. There is so many good tips here I just love this site.
Don't give up on the board !

I agree!!!!!!!!!!!!!!

Perfect timing. I am literally on my way to HF to buy the blades. Will try a package to see how they work. For those whose fabric won't cut cleanly, are your cutting only a single layer of fabric or multiple layers? I never cut more than one layer at a time. Yes, I know this is more time consuming, but I feel I have better control of my cuts when I only do one layer at a time, so this is what I do. This is totally my preference, not right nor wrong...to each his own, as they say. Will let you know how I like the HF blades. I only wish they made them in the 28mm size as this is my preferred rotary cutter size. Oh well, we can't have everything in life, can we? Have a wonderful day and keep on quilting! :-)

I love Harbor Freight blades. Use them all the time in my Olfa cutter. I have had a couple of bad ones but at the price I can afford a bad one once in a while.

the ones I tried worked just as well. But if you tighten the screw nut on the rotary cutter too tight it won't matter what blades you use or where you bought them, they will not turn, and therefore will not cut. Been there, done that!

The blades are advertized as carpet cutters, they fit 45. You can order on line, or, if your near a store look in the paint dept. They sell 2/1.99 when I last checked. Sometimes they have a sale
