Double edged with a double guard. The BD4 CONTRACTOR 's double guards function as flippers for a quick opening system. Plus the BD4 CONTRACTOR has a partially serrated blade to make it a great multi-functional folder. A generous EDC that might not be legal in some areas. Excelent for self-defence.

BLADE: The BD4 CONTRACTOR does not have the thumb studs you commonly find on other Extrema Ratio folders. The double guards perform double duty: protecting your hand and easy rapid opening. Streamlined spear point with partially serrated edge – very useful for EDC needs. This model has a desert handle and a stone washed blade.

HANDLE: The BD4 CONTRACTOR has a handle that is tapered and has Extrema Ratio's characteristic shaping to give your an enhanced grip. It has a bridge clip that folds over the end. This allows you to have a deep carry with only the clip exposed.

LOCK: The BD4 CONTRACTOR has a liner lock.
