Abstract: A blade adapter for a hacksaw is connected to the spine of the hacksaw and includes three connection portions. The hacksaw blade is connected between the engaging portion connected to the handle of the hacksaw and one of the three connection portions of the blade adapter to set the hacksaw blade at two different angular positions relative to the spine. The hacksaw blade can be set to be parallel to the spine or at an angle relative to the spine. A jabsaw blade is able to be connected to the front end of the hacksaw.

Abstract: A hacksaw includes a frame and a handle. A lever is pivotally coupled to the handle. A link has a rear end pivotally secured to the bottom portion of the lever. A blade is secured between the link and the frame and is secured in place when the lever is rotated to engage with the handle and is released when the lever is disengaged from the handle. A latch may secure the lever to the handle when the lever secures the blade in place. A bolt is threadedly engaged with the lever and the link for moving the link relative to the lever and for adjusting the blade tension when the lever secures the blade in place.

Abstract: A box cutter includes a housing with a blade slide slidably received therein. A pivotal member is pivotably connected to of the blade slide. An inclined face is defined in one of surfaces of the pivotal member and is gradually raised. The inclined face is connected to a pressing area which has two respective rounded guide portions. A spring is connected between the pivotal member and the housing to maintain the blade slide at the initial position. A button is slidably connected to outside of the cover and a spring is connected between the button and the cover. The button is moved to move the blade slide from the initial position thereof to an extended position. When the blade is cutting a workpiece, the blade is tilt and the pivotal member is pivoted by the cover so that blade slide is retracted into the housing.

Abstract: A blade replaceable hacksaw includes a spine with a handle connected thereto. A tension adjustor and a first blade securing portion are connected to the first and second ends of the spine. A positioning block is pivotably connected to the second end of the spine and a second blade securing portion is formed to the positioning block. A protrusion extends from the first end of the positioning block. A stop is connected to the second end of the spine and has an inclined face and a top face. When the positioning block is pivoted upward and supported on the inclined face, a first blade is connected between the first blade securing portion and the tension adjustor. When the positioning block is pivoted downward and the protrusion contacts the stop face of the stop, a second blade is connected between the second blade securing portion and the tension adjustor.

Abstract: A utility knife includes a fixed blade in a first handle at one end and a self-retracting blade in a second handle at the other end. The utility knife further includes a locking member slidably positioned on a bifurcation of the second handle adjacent the first handle. In a locked position of the locking member either blade can be used. The locking member is adapted to slide toward the first handle to disengage the housing of the second handle from the first handle prior to replacing the self-retracting blade. A user may have two blade options when using the utility knife, thereby increasing working efficiency.

Abstract: A utility knife includes a housing having a compartment for receiving one or more spare knife blades, a blade carrier slidably received in the housing for supporting and moving a knife blade into and out of the housing, and a pushing device for selectively pushing and feeding one of the spare knife blades into the blade carrier without opening or detaching the housing. A pusher is slidably received in the housing and has an edge for engaging with and for moving the spare knife blade to the blade carrier, and a spring element may move the pusher relative to the housing and to offset the pusher from the spare knife blade. A hand grip may be used to move the pusher relative to the housing.
