Often made of very precious materials and embellished with the finest artwork of their time, razors are found in elaborate displays at knife shows, antique shops, and flea markets. The authors have broadly revised and expanded their detailed price guide, updating all values. This new third edition delivers a discussion of factors that determine collector value, an appraisal chart of razors, notes on extended appraisals, and listings of companies and base values, making this the best scale available to determine a comparative collector value for every razor. Over 200 companies, new pictures and illustrations, a chapter to help in identifying handle materials, and a chapter to aid in determining razors ages have all been added to this value guide. 2007 values.Ritchie, Roy is the author of 'Standard Guide to Razors ', published 2007 under ISBN 9781574325508 and ISBN 1574325507.
