The Case 88 4 blade Congress pattern is one of the most recognizable pocket knives ever produced by W.R. Case & Sons. Manufactured in variations such as the 5488 (stag handles) and 6488 (bone handles), the 88 pattern is one of the most collected knives out there. Its four blade configuration, typically consisting of two larger blades (spear & sheepfoot blade) and two smaller blades (pen and coping blade), made it an exceptionally attractive and versatile pocket knife. The four blade congress pattern, with its slightly curved handles, has its origins in the early 1800’s in Sheffield, England. Abraham Lincoln had a 4 blade Congress knife in his pocket the night he was shot in Ford’s Theater in 1865.
Case, among other American makers, began producing this pattern in the early 1900’s. They became popular for those who appreciated a larger (measures 4 1/8″ closed) heavy-duty congress design. Today, vintage Case 5488 and 6488 knives are highly collectible, particularly examples with desirable handle materials (green bone, stag), harder to find features (long pulls), or earlier tang stamps (Case Tested or Case XX era). Additional handle materials for 6488 knives include “rough black” (1940’s & 50’s) and jigged delrin (1970’s) handles.
Collectors also seek knives in excellent condition with original factory edges, making well-preserved examples increasingly difficult to find. Whether you’re looking to identify a Case 88 pattern or add one to your collection, the 5488 and 6488 remain classic examples of American pocket knife craftsmanship and continue to be favorites among Case knife enthusiasts.
