It takes a hard week, but there is some down time, so I work on something else while it sits in the oven or epoxy cures, etc. That's if everything goes right. The more a knife is complicated by size, geometry, or just being difficult, the more likely it becomes a closet knife. Taking this much time and materials causes one to be careful. I dont see how anyone can make a knife of any complexity can not work from a drawing and have the knife turn out like what is in the mind. Too many thing fightin ya.
