I bought the Tonic scissors with red handles and LOVE them. I cut 13 sets of stamps with them in the past week, and while I've always liked my KIA scissors for cutting rubber, these Tonic ones ROCK!
Plus the blades are tefflon, while they do get sticky they were not as bad as the KIA. I just cleaned them with goo gone and kept on cutting. I got mine at Archiver's and they were half the cost of the KIA scissors so I considered that a bonus! HTH
