I put a new blade in my rotary cutter about a month or two ago. The cutting was difficult and tedious so I thought that I may have put an old blade (dull) on it tho it had come out of the package. Today, I was going to change that darn blade and when I took it off of the cutter.....I noticed that it was actually TWO blades!
Silly me! I guess I did not pay much attention when I put it on the last time and the oil had kept both blades adhered to each other. After a silly giggle, I separated the blades and now I am happily cutting away without the fatiguing myself! lesson learned!
