One day several years ago, I got home from work and sat down to tie some flies. As I started, I picked up my rather new razor scissors and cut the thread. Or at least I tried to cut it. It merely folded over the blades. WTF!? What happened to my scissors! I yelled to my little girl who was about 5 years old then and asked her what she did to my scissors. She said she din't use them, but told me that her mom did. I asked her mom if she used them and she said she did. She used them to cut out paper snowflakes. I told her that they were ruined and wouldn't even cut butter. I sat there for an hour trying to force them to cut thread but nothing. They were shot. As a last resort, I picked up a small file I had for hooks. I ran the blade across the blades at an almost 90 degree angle. I figured it was worth a try and when I cut with them, they felt like new! I had saved them! After that day, I have had to use that sharpener to touch up my blades from time to time. The razor scissors are awesome, but one of the main complaints are that they don't stay sharp and become dull soon after using them. Using this method, I've been satisfied with the results. Now, my blades are always sharp and my kids and wife know not to use them for arts and crafts. The file I use is available at most stores and is only about $7.00. It's a tool that will always be with me when I am tying.
