Abstract: A tape measure includes a post with at least first and second arms spaced from one another to form a longitudinal slot having an end aperture for coupling with a tape blade retraction spring. The post distal end anchors to a housing sidewall via a fastener, and a fastener engagement region of the post extends from the aperture to the fastener's terminus. A distinct reinforcing collar is disposed about the post's distal portion and acts to limit movement of the arms away from one another. The collar may overly the post for at least half of the fastener engagement region and/or may abut a shoulder on the post. The fastener may have a first pullout resistance level without the collar present and a second higher pullout resistance level, advantageously double or more, with the collar present. Also, methods of assembly are described.

Abstract: A hand operated file is provided with a thin ceramic coating of a transition metal nitride, such as vanadium nitride and/or zirconium nitride, on its teeth. The coating may be 20 um or less, thereby not altering the macro dimensions of the file. The coating may be applied using a vapor deposition process such as physical vapor deposition, and advantageously via a physical vapor deposition process where the file body does not exceed a temperature of about 300° F. The coating helps prevent galling, thereby increasing the useful life of the file.

Abstract: A tape measure housing, and a tape measure incorporating the housing, includes a main case and an elastomeric grip element mated to the main case. The main case has first and second sidewalls and a peripheral wall extending between the sidewalls which help jointly define an internal chamber therewithin for housing the coilable tape blade. An elastomeric grip element having a perimeter edge is disposed over at least a portion of the top portion, at least a portion of the rear end portion of the case, and at least a portion of the first and second sidewalls. The outer surface of the first and second sidewalls is external recess-free proximate the perimeter edge of the grip element.

Abstract: A manually powered cutting tool with cutting force at the cutting jaw faces that is multiplied several times by the mechanism, leading to a much higher maximum available cutting force than possible with conventional snips. The maximum magnitude of the cutting force applied to the workpiece may be much larger due to multiple stages of force multiplication present in the mechanism. The multiplication factors are established by the structural geometry built into the tool.

Abstract: A magnetic end hook for a tape measure has a hook member having a mounting section extending in a first direction and a hooking section extending away from the mounting section in a second direction generally transverse to the first direction. A distinct bezel affixes to the hooking section so as to capture a magnet between the bezel and the hooking section. A magnet is disposed at least partially in a hole in the hooking section and a hole in the bezel so as to be visible from both front and rear views of the end hook. The magnet may include flanges and a fastener, such as a rivet, may secure the bezel in place. There may be a second magnet similarly situated. A tape measure and methods of assembly are also described.
