So, When is the Optimal Re-Sharpening Point? Based on this graph, we can see that there are points in the life of the blade when cut quality starts to drop off drastically. This is the optimal re- sharpening point. This point may vary depending on the specific use.

Proper maintenance of saw blades is very important. Depending on the usage the blade can be re- sharpened between 10 and 20 times. Optimal maintenance guarantees: - Good cutting quality - Good running behavior of the saw blade - Long edge lives - Optimal overall lifetime of the saw blade Maintenance
Maintenance is not sharpening only. Usually it includes: - Cleaning of the blade - Complete removal of tooth wear from the face and from the top - Maintaining the geometry of cutting edges. - Tensioning and straightening, if necessary - Tooth replacement in case of heavily chipped teeth Maintenance
