Bill-
I'm very sad to hear of your losing your father. Parents are very difficult to lose, and I still think of Dad whenever I see a new challenge. Guys from their era were not just our own special friends, mentors, and protectors, but a special breed from a generation who were extremely self-sufficient, innovative, and often brave and generous. I always think of Dad fondly whenever I use his tools and remember our times together. May you find comfort in remembering your good times together too. 'sincere best wishes.
