I use them, and I love them. Have had no problems. They are sharp enough to cut thru 8 layers of fabric and do it accurately. I dont normally try to cut thru that many layers it was a test, and they passed.

I love mine. I bought twenty packs last year and I have only opened two of them. They last for months at a time and I used them every day. Sorry some of you have had bad luck with them.

I've had good luck with my Harbor Freight blades. Don't see any difference.

I have used several.Was pleased with some and others were not even usable.Buyer beware,,,my 2 cents..

I can't imagine that carpet can be cut with the blades that I bought at HF because they wouldn't even cut fabric!!! I threw 4 of them away and will never waste money on them again.

I too use and love the HF blades. Mine last me for months and thru many projects before going dull and having to be changed. I don't understand why some people have problems with the blades, I only know I never have.

I have not had any problems w/my blades. They are suppose to be used by carpet layers. So I don't understand that some people found them dull. For $2 their fine by me.

I really like the blades. I have not had one problem with them. Others have used them not knowing they were "cheap" blades and didn't have a complaint until they found out what they were. I can't help but wonder how much the opinion is based on the cost or name brand of certain items. I have also had comments on how much others have liked using my stiletto until they found out it is a dental pick found at the grocery store.

Blades from harbor freight
 

I recently bought a 2 set of 5 blades in the pink holders. So far I have cut out a day & night quilt with one blade and the blade is still sharp. As for a wobbly blade, flatten out the black piece under the blade, this worked for me. If I can find them on sale again, I will buy them. Good luck with yours.

Gee, I love mine too!!
