The blades for the Silhouette can last up to six months. This, however, is an estimation only. The actual blade life will be dependent on usage and the type of material being cut. Thicker materials will wear down the blade much more quickly. In some cases this may be as low as a few weeks to a month. Variables to take into consideration would include (but not be limited to) the following:
Attempts to cut certain materials the Silhouette may not be designed to cut that are more dense may ruin the blade or result in the blade dulling extremely fast. Additionally, certain papers with bits or particles of foreign objects may immediately impair the blade. We strongly recommend against cutting materials with additional foreign objects embedded into them which may harm the blade.
Replacement blades are available for purchase.
