Abstract: One embodiment for splitting logs is described as including a first handle; a second handle; a unitary body wedge comprising a cutting wedge coupled to the first handle and a splitting wedge coupled to the second handle, wherein the first handle and the second handle are co-aligned along an axis of the log splitting tool when the cutting wedge and the splitting wedge form the unitary body wedge. As a user swings the log splitting tool in an overhead arc, driving the unitary body wedge into a log that is to be split, a cutting edge of the cutting wedge is driven downward into the log. The user spreads the first and second handles apart in opposing directions so that leverage created by the length of the first and second handles force the cutting wedge and the splitting wedge to separate apart from each other, causing the log to split.

Abstract: A shearing tool has a first unit with a first blade, rotatably coupled to a second unit with a second blade, at a first pivot having a first pin, so that displacement of the first blade relative to the first pin in a direction parallel with a first rotational axis is prevented, and the handle is connected to the second blade so that rotational movement of the handle relative to the second blade about a second rotational axis is allowed. The second rotational axis is defined by a second pivot interacting with the second blade and the handle at a distance from the first rotational axis in a direction away from a cutting edge contact point. When the shearing tool moves from an open to a closed position, the second blade is driven towards the first blade at the contact point for increasing the cutting capacity of the shearing tool.

A hard coating joined to the substrate has a thickness of 700 Angstroms to about 3500 Angstroms. An outer layer joined to a coated substrate is discontinuous. The outer layer may be produced from a dispersion comprising about 0.03 g/L or less of telomer or from about 0.5 % solids or less of telomer by weight of composition. The novel razor blade cuts at less than 100 % cutting efficiency using a single fiber cutting efficiency measure.
