Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener includes an abrasive medium having an abrasive surface. A stationary tool support guide provides a guide surface that supports a side of the tool during presentation of a cutting edge of the tool against the abrasive surface. A rotatable edge guide has a roller member with a curvilinearly extending outer surface. The roller member is rotatable about an edge guide roller axis to engage, via rolling contact, the cutting edge during the presentation of the cutting edge against the abrasive surface.

A sander includes a housing defining a front end and a rear end relative to a direction of travel of the sander on a work surface, an actuator, and a battery platform. The housing supports a motor and has a grip disposed over the motor adjacent the front end and a handle positioned at or adjacent the rear end. The housing further supports a belt drive assembly configured to rotatably support a belt and having a belt plate extending a long a first plane. The actuator is supported by the handle. The battery platform is at least partially supported by and located above the handle. The battery platform defines a battery pack receptacle configured to support a battery pack. The battery platform is oriented along a second plane orientated at an acute angle relative to the first plane.

A belt sander includes a grip portion, an electric motor, a first operating unit, and a second operating unit. The grip portion is configured to be gripped by an operator. The electric motor is configured to drive a sanding belt. The first operating unit is configured to perform an on-operation of the electric motor and configured to keep the on-operation. The second operating unit is configured to perform an on-operation of the electric motor. The electric motor is rotated by the on-operations of both the first operating unit and the second operating unit. The second operating unit is disposed at a position where an operation is allowed by a hand that grips the grip portion.

The belt sander includes a gear casing coupled to a tool housing, the gear casing surrounding one or more gears configured to receive input from a motor to drive a shaft about a drive axis. The belt sander includes a belt arm assembly having a belt arm, the belt configured to translate in response to input from the shaft. The belt sander includes a plurality of incrementally spaced apart receivers on the gear casing and an engagement member in operational communication with the belt arm assembly, the engagement member being movable between a locked position and an unlocked position, wherein in the locked position the engagement member engages a receiver to fix the belt arm assembly incrementally relative to the gear casing, and wherein in the unlocked position the belt arm assembly freely rotates relative to the belt arm assembly to pivot the belt arm about the drive axis.

Particular embodiments of the inventive technology relate to apparatus and methods for cutting multi-layered material to reconfigure it so it may be used to construct sub-compartments in a larger storage container. The inventive technology, in particular embodiments may feature one or more of the following: dual blades, staggered blades (where one blade is more forward than another), a blade(s) angled upwards and forwards, blades separated in a left-right direction, prong recesses to accept trailing tips of blades, a rearwardly angled handle and/or a removed material ejection ramp, in conjunction perhaps with other features such as, e.g., a guide prong. One or more of such features may appear in the various manifestations of a defluting cutter or through cutting apparatus, whether guided or unguided, and/or manual or powered.
