This listing is for a vintage Case Tested XX 3-blade whittler pocket knife dating from the highly collectible Tested era (approximately 1920–1940).

The knife features beautiful brown jigged bone handles with nickel silver bolsters and an oval CASE shield. The tang stamp on the master blade reads “CASE TESTED XX” in the classic cursive Tested-era stamp.

This traditional whittler pattern includes:

• Master clip blade

• Coping/wharncliffe secondary blade

The knife shows honest age and use throughout, including patina, pitting, sharpening wear, and surface discoloration consistent with an authentic vintage carbon steel pocket knife. Handles appear original and remain attractive overall.

Please review all photos carefully for exact condition. This is a genuine old Case knife with excellent collector appeal and classic Tested-era character.

• Vintage CASE TESTED XX tang stamp

• 3-blade whittler pattern
