W.R. Case & Sons Cutlery Company is proud to debut the Sway Back Jack--the newest Case pattern and latest design collaboration with award-winning custom knife maker Tony Bose. Inspired by English Jack knives from the 19th century, the Sway Back Jack may just be the perfect gentleman's knife, as well as the perfect ladies' knife for the 21st century. The elegant curve of the handle, the Wharncliffe blade with dramatic swedge and pen blade with extension spring--the features are classic Tony Bose, and the style classic Case.
