While they do hold some sentimental value, I am wondering if they're worth the cost/effort of repairing if/when they break. He had the Echo saw for as long as I can remember. The Stihl is no spring chicken either. Both work and seem to still run great. I also inherited about 10-15 newly sharpened chains as well.
