摘要: Hand tools which have an ergonomic using a palm handle and finger handle designs which achieve mechanical efficiency and ease of use. The ergonomic handle is compatible with the muscle movements of an operator using a hand tool reducing muscle strain and pain. Optionally, the palm and finger handles can have ergonomically designed cushions. In an embodiment, the finger handle can have a finger set which has a forward finger flange, a tail finger flange and a pinky grip. The ergonomic handle can also use a relief washer system to achieve a smooth low frictional resistance cutting stroke.

摘要: A knife includes a handle portion and a cutting head portion. The cutting head portion includes a lid portion and a base portion configured to receive a blade therebetween. The lid portion is coupled to the base portion by a hinge. Rotation of the lid portion relative to the base portion away from the base portion opens a space above the base portion through which the blade may lifted. A method of removing a blade from a knife includes rotating a lid portion relative to a base portion about a hinge coupling the lid portion to the base portion, further rotating the lid portion until a protrusion fixed to the lid portion extends through the base portion and lifts up on the blade to create a gap between the blade and the base portion, and grasping the blade at the gap to pull the blade away from the base portion.
