A hacksaw with an improved mechanism for applying and adjusting the tension on a blade mounted to a blade mount on a front arm and a blade mount on a rocker arm. The rocker arm is pivotally coupled to a handle and is spring biased to place an initial tension on a blade held by the rocker arm and the front arm. A rotatably mounted lever is positioned on the handle for vertically displacing a nut captured in the rocker arm to pivot the rocker arm and adjust the tension on the rocker arm-held blade. An elongate top frame bar of the hacksaw defines a hollow I-beam cross-section accessible from the face of the front handle and is capable of storing saw blades. A bale screw is positioned in the front member for securing the blades in a position extending past the front handle.

Hacksaw with blade tensioning mechanism

Hole saw

A coated hole cutter including an ink-based colored coating applied only to the external surface of the cylindrical blade body of the hole cutter, but not to the surfaces of a circumferentially-extending cutting edge or to the interior surface of the blade body. The ink-based color coating is an ultraviolet activated ink that cures when the coating is exposed to a specific ultraviolet light intensity and wavelength. At least the surfaces of the cutting edge and the internal surface of the blade body, which do not include the coating, have a steam tempered oxide finish that imparts a color that contrasts with the color imparted by the coating.

Coated hole cutter

A device for storage and transfer of tools and supplies that includes a housing, a cover and a handle. The housing defines a storage area therein and is configured to receive a plurality of tools and supplies. The cover is pivotally attached to the housing and is movable between a closed position covering the storage area and any tools and supplies therein, and an open position at least partially exposing and permitting access to the storage area and any tools and supplies therein. The handle is pivotally attached to the housing and is movable between a storage position located within the housing and a use position projecting from the housing for carrying the device thereby. The cover is movable between the closed and open positions while the handle is either in the storage position or the use position.

Storage tote

A gauge protector extends about an exterior surface of the gauge. A first relatively soft zone of the protector protects the gauge from damage by shock or impact. A second relatively hard zone of the protector is located adjacent to the first relatively soft zone and is resistant to abrasion for protecting the gauge from damage by contact with abrasive surfaces.

Gauge protector

A kit for carrying hole saws has a hole saw carrier configured to releasably carry thereon a plurality of nested hole saws, and is movable between (i) a storage position and (ii) a use position for removing one or more hole saws therefrom. The carrier is axially-elongated and receivable through an arbor hole in a hole saw to releasably carry the hole saw thereon and to allow one hole saw to be nested within another thereon. The carrier is pivotally mounted and movable between the storage and use positions.
