"Almost a decade after we presented our book Las Otras Marcasʺ and five years since the Guía Argentina de Cuchillosʺ, we offer the reader this new corrected and augmented version of these works.ʺ (HKB Translation) --Page 5. This third title on this subject is the outcome of new research -by the authors and in collaboration- with the contribution of other invited specialists. The marks register -with its images- evolves with new findings and is enriched with detailed information. In this aspect, some marks of silversmiths gain prominence by deserving exclusive chapters, as is the case of Herder, Kirschbaum y Weyersberg, and La Movediza of Tandil. In addition, the edition includes brief essays on the old armories of Buenos Aires, the sabers that the gaucho in Argentina used on many occasions to build his facones and caroneros throughout the 19th century and, and the group of silversmiths recognized for their work in criollaʺ cutlery.
