The friction (resistance) felt when opening and closing the Belsizer is intentionally designed from the product development stage. In particular, to prevent foreign matter contamination while reliably cutting thin polyethylene (PE) and polypropylene (PP) films used in food factories, we prioritize the precision and tracking of the blades' engagement.
As a result, the blades are assembled with a slightly tight fit to minimize play, which may cause a slight sensation of friction in the initial state. This is a design feature to maintain the blades' firm engagement and cutting force.
In practice, as the product is used repeatedly, the components become more familiar with each other, and the resistance gradually decreases. Many users have praised the product, stating that “it becomes smoother with use, and the sharpness of the cut becomes more noticeable.” We hope you will feel assured that this is a natural performance characteristic of the product.
