A 261-DS Stag Coffin Jack post A.G. Russell era. This knife is a Jim Frost era Bertram Cutlery version of the famous Bertram CM-6 Coffin Jack. Despite the fact that it was made after the original Bertram factory ceased to exist and the brand of Hen & Rooster knives became the property of James Frost, this 261-DS is still a very fine quality Coffin Jack with beautiful stag handles.
