Locking foldable knife

A knife comprising:

• a handle;
• a first stop disposed on the handle, the first stop having first and second sides;
• a blade mounted to the handle and being rotatable between folded and unfolded states relative to the handle, the blade defining an unfolded locking edge and an unfolded receiving edge, the unfolded receiving edge on the blade in the unfolded state being configured to engage the second side of the first stop;
• and
• a locking bar disposed on the handle and being slidable between extended and retracted positions along an axis relative to the first stop, the locking bar having first and second edges opposing one another along the axis, the first edge of the locking bar in the extended position being configured to engage the unfolded locking edge of the blade in the unfolded state, the second edge of the locking bar in the extended position being configured to engage the first side of the first stop at least with the blade in the unfolded state,
• wherein the blade defines a slot disposed between the unfolded receiving edge and the unfolded locking edge;
• and
• wherein a distal end of the locking bar in the extended position is configured to position at least partially in the slot of the blade in the unfolded state.

A knife comprising:

• a handle;
• a first stop disposed on the handle;
• a blade mounted to the handle and being rotatable between folded and unfolded states relative to the handle, the blade defining an unfolded locking edge;
• and
• a locking bar disposed on the handle and being slidable between extended and retracted positions along an axis relative to the first stop, the locking bar having first and second edges opposing one another along the axis, the first edge of the locking bar in the extended position being configured to engage the unfolded locking edge of the blade in the unfolded state, the second edge of the locking bar in the extended position being configured to engage the first stop at least with the blade in the unfolded state,
• wherein the blade defines a folded locking edge;
• and
• wherein the first edge of the locking bar in the extended position is configured to engage the folded locking edge of the blade in the folded state.

A knife, comprising:

• a handle;
• a first stop disposed on the handle;
• a blade mounted to the handle and being rotatable between folded and unfolded states relative to the handle, the blade defining an unfolded locking edge;
• and
• a locking bar disposed on the handle and being slidable between extended and retracted positions along an axis relative to the first stop, the locking bar having first and second edges opposing one another along the axis, the first edge of the locking bar in the extended position being configured to engage the unfolded locking edge of the blade in the unfolded state, the second edge of the locking bar in the extended position being configured to engage the first stop at least with the blade in the unfolded state;
• and
• a second stop disposed on the handle, wherein the blade defines a folded receiving edge, the folded receiving edge on the blade in the folded state being configured to engage the second stop.

A knife comprising:

• a handle;
• a first stop disposed on the handle and having first and second sides;
• a second stop disposed on the handle;
• a locking bar disposed on the handle and being slidable between extended and retracted positions along an axis relative to the first stop, the locking bar having first and second edges opposing one another along the axis;
• and
• a blade having first and second ends, the blade being mounted at the second end to the handle and being rotatable between folded and unfolded states relative to the handle, the second end defining a folded receiving edge, an unfolded receiving edge, a folded locking edge, and an unfolded locking edge,
• the folded locking edge on the blade in the folded state being configured to engage the first edge of the locking bar in the extended position,
• the folded receiving edge on the blade in the folded state being configured to engage the second stop,
• the unfolded receiving edge on the blade in the unfolded state being configured to engage the second side of the first stop,
• the unfolded locking edge on the blade in the unfolded state being configured to engage the first edge on the locking bar in the extended position,
• the second edge of the locking bar in the extended position being configured to engage the first side of the first stop,
• the first edge of the locking bar in the retracted position being configured to disengage from the folded and unfolded locking edges.

A knife comprising:

• a handle;
• a first stop disposed on the handle;
• a blade having a proximal end rotatably mounted to the handle, the blade being rotatable in an unfolding direction from a folded state to an unfolded state relative to the handle, the blade being rotatable in a folding direction from the unfolded state to the folded state relative to the handle, the proximal end defining a first locking edge facing the folding direction;
• and
• a locking bar disposed on the handle and being movable between an extended position and a retracted position relative to the first stop and the proximal end of the blade, the locking bar having first and second edges opposing one another, the first edge opposing the folding direction, the second edge opposing the unfolding direction,
• the first edge of the locking bar in the extended position being configured to engage the first locking edge when the blade is in the unfolded state,
• the second edge of the locking bar in the extended position being configured to engage the first stop when the blade is in the unfolded state,
• the first edge of the locking bar in the retracted position being configured to disengage from the first locking edge when the blade is in the unfolded state.
