Abstract: There is disclosed a holder for a clasp knife in which the blade is held in a slot in a partly open condition but with the blade still spring-pressed to closed position so that the handle of the blade is held tightly in the holder and yet is accessible to the hand of the user and can be pulled outwardly and upwardly in one smooth motion to both release the knife from the holder and to open the blade. The holder has a slotted face conforming to the front of the knife and a roller spanning the slot in position to be engaged by the tip of the knife blade so that the spring-bias to closed position will pull the handle of the knife into juxtaposition with the slotted face. The holder has bottom and top projections adapted to hold the pivot end and free end of the knife against longitudinal movement. The bottom projection has a dish-shaped depression therein to hold the pivoted end against being withdrawn from the holder until after the free end has been withdrawn.
