I have noticed that my cutters have begun to stick more often than not. All of my stringing tools have come from the original set that ships with Gamma machines, and they are all pretty heavily rusted at this point. They all still do a good job, but have seen better days. Additionally, my starting clamp is slipping when tension is pulled against it, and i'm wondering what I could do about that? It appears to have lost some of its gripping surface. What do you do to maintain your tools, and what can I do? Also, do they make these in stainless steel or anything higher quality than what I currently have?
