Carpet Cutters from Harbor Freight
Well, I finally got some; two packages. I figured these would last me for quite awhile. When I got home, oh so anxious to try them. Alas! they didn't cut an inch; not even a thread. I am so disappointed. I'm sure you're thinking, "I bet she put both blades in her cutter handle".
But yes, I made sure it was just one blade before I started cutting. I took it off the handle and cleaned it off; turned it around. Nothing! It would not cut!!! The price is not worth the trip to take them back. Anybody need any carpet cutters? :)
