This book documents his workshop and parts of his hand written workbook. Nahum came from a generation that didn't have a lot of extra money, so if they needed something they had to make it. The value of this book is to give the blacksmith and other metalworkers a foundation to do Detail and Definition work, specifically Ornamental Metal. The German method of embossing is what Nahum Hersom teaches; he learned his craft from Mr.Valatine Goelz.
