I’m not into production work, and to me the phrase, ”one-at-a-time” means exactly that. Taking the time with hand tools means closer examination of the material, and the discovery of perfections, and imperfections. Machines certainly have a place, they are great for dimensioning wood from rough to usable, but nothing is quite like the human element of hand tools. However, dimensioning rough lumber with strictly the use of hand tools is draining, and time consuming. In my shop, hand tools are saved for the final touches, and used for more delicate matters. While physically I do only work on one piece at a time, cabinet, box, or a bass guitar, I’m still planning the next one.
