We only carry extra blades for the MultiCutter. Can you email a video of this problem to [email protected]. I have never heard of the multicutter getting stuck before. I would need to see it in action to help. But just as general advice, you could try hitting it with some machine lubricant or WD-40. We typically recommend using Food Grade Silicone based Machine Lubricant on our button making equipment becuase it leaves a less greasy film and is less likely to ruin your button prints. But really any machine oil will work. Anywhere that metal touches metal, you have to keep it lubed.
