How long will the My-T-Fine Cutting blades last?
• While the My-T-Fine Cutting blades are self-sharpening, it is virtually impossible to predict their life. • Depending upon the weight, thickness and abrasive characteristics of the materials being cut, the life can vary dramatically. For typical light to medium weight materials that are not particularly abrasive you should be able to get approximately 2 hours of use per day for three to four months before the blades need to be replaced. • It is also possible that the My-T-Fine Cutting Blade set may develop a burr on one or more of the blades for reasons such as cutting through a particularly hard material or items such as straight pins or staples, in which case the blades will need to be replaced.
