My daughter lives near one of those Harbor Freight places. I had called them and wanted $6.99 to ship some. I waited until I went down there. They worked good. They were $1.59 per each. Then I also went to Joannes 1/2 off wsale and bought a rotary cutter sharpener and after DH showed me the right way to use it, I never have a dull blade. I have a full supply of fresh ones too.
