Abstract: Blender and food processing devices are described that dampen impact forces between a blending blade and a blending jar. An example blender includes a blender base and a blending jar that has a seal opening. A blending blade assembly in the jar includes a blending blade, a jar shaft attached to the blending blade and extending through the seal opening, a circular motion guide positioned around the jar shaft, and a jar seal positioned between the circular motion guide and the seal opening. The jar seal prevents contact between the circular motion guide and the seal opening and dampens forces induced by relative motion between the seal opening and the blending blade, jar shaft, and/or circular motion guide. A motor in the blender base drives the jar shaft to rotate the blending blade in the blending jar. The dampening may reduce wear or damage to the jar and may improve quality of the blending jar and blade assembly.

Abstract: A hand tool having first and second plier units attached to one another where a jaw region is operatively configured to have a work piece to be placed therein and a handle region is configured to be used by the user of the tool to grasp the work piece. A tension member is provided to be positioned past a dead point axis so as to apply a clamping force upon the jaw member and the hand tool maintains a grip upon the work piece without continuous interaction with the user of the tool.

Abstract: A blade configured for use in a blending apparatus includes a body portion and a pair of wing portions extending from the body portion. At least a leading edge of the blade is forged to increase a hardness property. The leading edge may have a minimum thickness that provides a relatively blunt leading edge. The wing portions of the blade may be formed after forging the blade.

Abstract: A torsional joint assembly formed from a substantially planar material sheet comprises a plurality of contiguous segments. The contiguous segments include at least two, substantially parallel hinge segments, each being coupleable to a loading structure; and at least a first connecting element connecting the hinge segments one to another, the connecting element extending substantially orthogonally to the hinge segments.
