Patented American Sawsets: An Illustrated Patent Directory, 1812-1925, by Todd L. Friberg. 306 Pages. Softbound. This book expands upon the trend begun by Jim Price, Ken Cope, and Ron Pearson in providing topical references to all patented tools of a particular type. The Friberg book is illustrated with the patent drawings of every known patented sawset and includes indexes that allow easy location of a particular tool based on date and the name of the patentee. All sawsets are rated by relative scarcity. This is a fascinating reference that brings a previously under-appreciated topic to life. An excellent addition to the collector's library. $23.95 (BK-0024)
