For many decades, Polar paper cutters have been some of the most popular and reliable models on the market. This fact simply means that there are a lot of different Polar cutters on the market and thus a lot of need for replacement knives. To help meet that need we carry a huge selection of blades and knives for Polar models including the 115, 155, 82EL, 90CE and so many more. In fact we either stock or can get a blade for virtually any model on the market. Take a look at the options below, find your model and double check to make sure the length and hole patterns match.
