Abstract: A liner for a folding knife includes a curved elongated spring to bias a blade of the knife to an open or closed position. The spring may extend in an arc from an origination point to a free end, within a cutout region of a body of the liner. The spring may be J-shaped in one approach. The spring may be integrally formed with the liner or formed as a separate piece which is attached to the liner. The free end may include a shoe to contact a lock stud in a handle of the knife. The origination point may be below and frontward of the shoe. The spring biases the lock stud frontward to lock the blade in the open position. To close the blade, the user moves the lock stud rearward, against a spring force of the spring, allowing the blade to rotate to the closed position.

Abstract: A golf club having improved visual feature recognition includes a golf club head coupled to a golf club shaft. The golf club head includes a hosel defining a bore, a sole, and a design attribute that is generally not capable of easy visual discernment. The bore has a first portion having a first diameter, a second portion having a second diameter that is smaller than the first diameter, and a transition from the first diameter to the second diameter. The bore extends through the golf club head to the sole, and the golf club shaft is disposed within the first portion of the bore and secured to the hosel. A polymeric plug is disposed within the bore between the golf club shaft and the sole. The polymeric plug includes a restraining feature that contacts the transition to prevent withdrawal of the polymeric plug through the sole, and is a color that corresponds to the design attribute.
