I know may comments have been posted about these blades--both good and bad. I opened my first packet of them today and I couldn't cut with them! I had to press really hard to cut paper. I turned the blade around thinking maybe it only had one cutting side--still not luck. I was just so mad that I had to tell someone!

Sorry, never tried them so I am clueless! LOL

return them! ... defective product.

I bought unopened Olfa blades on ebay for the same price as the Harbor Freight blades so I have no reason to try them. I'm sorry yours were bad. It has to be so frustrating for you.

so far, I have had really good luck with them---sorry your experience hasn't been good.

Have tried 3 packs all bad

Me Too I have purchased "brand name" blades and they wouldn't cut. Sometimes you get a bad product, I guess.

I heard the same thing about them. Someone said they heard they were recycled blades, which didn't make sense to me.

I have purchased about five or six packs of Harbor Freight blades. Out of those, one pack was bad. Take 'em back and order from a different batch-- i.e., not the same shipment that you got them from (if you purchased them at the physical store).

Return them. They won't know they have defective merchandise unless we tell them.
