Problems solved by technology

[0003] However, such conventional assisted opening folding knives are often difficult to operate and may injure the user's fingers or hands when the user is not familiar with the operation of the assisted opening mechanism.
For example, some assisted opening folding knives may require the user to place the user's thumb dangerously close to the blade of the knife in order to actuate the knife blade
In addition, the knife blade of such an assisted opening folding knife may be difficult to deploy and may require the user to hold the handle of the knife with one hand and pull the knife blade with the user's other hand in order to fully deploy the knife blade
In other cases, some assisted opening folding knives may unintentionally unfold when part of the user's body or an object is swept over a protrusion on the knife blade

Embodiment Construction

[0029] figure 1 An exploded perspective view of folding knife 100 with a button assisted opening mechanism in one or more embodiments is shown. In one embodiment, the folding knife 100 can include a handle 104 having a first outer handle side 114, a first inner handle side 116, a second inner handle side 118 and a second outer handle Shank side 120 . In other embodiments, the folding knife 100 can include a handle ornament or additional handle sides between or attached to the handle sides described above. The handle 104 can include a handle top 166 and a handle bottom 168 .

[0030] The handle bottom 168 can be a portion of the handle 104 configured to receive a user's fingers when the user holds the handle 104 in a handshake grip. For example, the handle bottom 168 can be defined by one or more handle grooves, finger rests, or grips along an edge of the handle bottom 168 . The handle top 166 can be the portion of the handle 104 configured to receive the palm of the user w...

One end of the spring is coupled to at least one of the at least two handle sides and the other end is coupled to the toggle member, wherein when at least a portion of the blade is folded into the blade cavity, the The drive pin is positioned within the retaining recess.

Description

technical field [0001] The present disclosure relates generally to the field of folding knives, and more particularly, to folding knives with button assisted opening mechanisms. Background technique [0002] Folding knives with an assisted opening mechanism are widely used by hunters, carpenters, and outdoor enthusiasts due to their portability and safety when folded. Conventional assisted opening pocket knives typically include a knife blade with a protrusion, such as a post, pin, or enlarged base, extending from an exposed portion of the knife blade when the pocket knife is in the closed position. When deploying such a knife, the user typically pushes on the protrusion to actuate the knife blade. [0003] However, such conventional assisted opening folding knives are often difficult to operate and may injure a user's fingers or hands when the user is not familiar with the operation of the assisted opening mechanism. For example, some assisted opening folding knives may r...
