A few years ago I bought so many new blades - it seemed like people were forever posting sites with great prices. So how do you pass up a good deal? Not sure, but I think at one time I had over 50 blades. And after a while the lubricant they use on them sticks them together. So when I change blades I have to use a hair dryer or set an iron on them to get them apart. Otherwise they stick together and it is hard to see if there is one or two, but once in the cutter, you can tell real fast.
