A device includes a handle, an apparatus for probing and cutting, and an adaptor. The handle includes one or more triggers. The apparatus for probing and cutting is connectable to the handle and includes an elongated member, a probe, and a blade. The probe and the blade are selectively deployable from the elongate member via activation of the one or more triggers on the handle. The adaptor is configured to selectively connect the apparatus to the handle in a predetermined orientation.

A folding knife includes a handle, a first liner inside the handle, and a second liner inside the handle and opposed to tire first liner. A blade has a tang and a cutting edge, and the tang of the blade pivotally connects the blade between the first and second liners. The blade has a retracted position in which the cutting edge is inside the handle and a deployed position in which the cutting edge is outside the handle. An actuator is at least partially between the first and second liners. A screw inside the handle has a first end opposed to a second end. The first end of the screw is engaged with the first liner, and the second end of the screw is threadingly engaged with the second liner.

An assisted opening knife blade having a knife blade and at least two blade projections extending from the knife blade, wherein a proximal end of each blade projection extends beyond a side surface of the knife blade.
