I love the paper trimmer but I feel like the blades get dull very quickly. I know it’s just what it is with this style of paper trimmer so I only buy them when they are on sale and I stock up.
I use my Cricut Portable cutter a lot. It’s lightweight and the blades last a long time. I keep these replacement blades on hand, so I don’t have to go to the store when I need one. They are very sharp and of good quality considering you’re cutting paper. I trust the Cricut brand for all my crafting.
