try the ones from Quilted Twins, the price is great

I have ordered them from Harbor Freight because of the cost. Each time some of the blades work very well and some don't work at all. The most frustrating happens when they are all I have left and I only have ones that won't cut at all. I worked out the math and even though I could not use some I still saved money. I kind of decided it is not worth the frustration...but I might try again.

Get the 10 pack from amazon. I have no issues with them and they are super affordable

I use these almost exclusively. They are cheap and I can buy lots of them and throw out the ones that do not work. Yes, some do not work well while others are not great. Most times a quick run through the blade sharpener works great. I used to purchase generic blades through JHittle an online site but started purchasing these. They work just fine for me.

I have not ordered from them, but we have one nearby. I haven't had any problem with them, I figure for the price, if I hit a pin or something and it gets dull, not a huge deal.

Apparently, all Amazon blades are not equal. I've purchased the "Premier" blades from amazon. They aren't very good. Most skip right out of the package. Since I have 10 of them, I will use them, but will not buy them again. (They aren't as bad as HF, which I didn't bother to use after the first try.) I just have to remember to run the cutter over every cut twice before I move my ruler.

Thank you! I placed an order for the 60mm blades and received it already.

The blades at Quilted Twins are the same as the ones I get on Amazon but right now both sites are out of 45mm. I've had good luck with them.
