Abstract
A pin includes: (a) a pin shaft with a pin point; (b) an elongate pin head attached to an end of the pin shaft distal to the pin point having a pin head length, wherein the elongate pin head is characterized by an elongate tapered ribbed construction with a plurality of ribs defining a rib profile extending from an outer end of the elongate pin head distal to the pin shaft to an inner end of the elongate pin head proximate the pin shaft, said rib profile having a characteristic outer end dimension which is larger than a characteristic inner end dimension of the rib profile proximate the pin shaft, said elongate pin head being further characterized by a plurality of outwardly projecting gripping rings located a distance from the outer end of the pin head toward the inner end of the pin head.

A pin comprising:
- (a) a pin shaft with a pin point;
- (b) an elongate pin head attached to an end of the pin shaft distal to the pin point having a pin head length,
- wherein the elongate pin head is characterized by an elongate tapered ribbed construction with a plurality of ribs defining a rib profile extending from an outer end of the elongate pin head distal to the pin shaft to an inner end of the elongate pin head proximate the pin shaft, said rib profile having a characteristic outer end dimension which is larger than a characteristic inner end dimension of the rib profile proximate the pin shaft, said elongate pin head being further characterized by a plurality of outwardly projecting gripping rings located a distance from the outer end of the pin head toward the inner end of the pin head.
A pin for use in sewing having an elongate cylindrical body tapering to a point at a first penetrating end and having a bulbous grasping/stopping enlargement located at an opposed second end of said elongate cylindrical body, said elongate cylindrical body having a diameter of at least about 0.25 mm up to about 1.5 mm, said bulbous grasping/stopping enlargement having a pushing portion at a terminus most distal to said point, said pushing portion having a convex cap having a diameter of from about 2 mm to about 5 mm across and a plurality of generally convex grasping rings encircling said elongate cylindrical body formed in said bulbous grasping/stopping enlargement, at least two of said grasping rings being spaced from said convex cap of said pushing portion by a distance of from about 4 to 15 mm, the diameter of said grasping rings being at least 0.35 mm greater than the diameter of adjacent portions of said bulbous grasping/stopping enlargement and being separated from the next adjacent grasping ring by at least about 2.25 mm.
