Deakin & Francis Black Saber Tooth Tiger Cufflinks C1443X0002. This prehistoric cat is famous for its large canines which measured up to 12 inches in the largest species. Their jaws could open up to 120 degrees but don't be fooled by their beastly look, the Saber-Tooth Tigers jaw and canines were both very weak and could be easily damaged in fights. Our Saber-Tooth Tiger cufflinks have a solid jaw and real, intense diamond eyes. With domed oval spring link fitting, these cufflinks come complete with a full set of Deakin & Francis hallmarks for authenticity and packaged in a Deakin & Francis unique presentation box and giftbag.
