An accessory for coupling to an attachment mechanism of an oscillating power tool includes a working end, an opposite rear end, and a fitment portion adjacent the rear end portion. The fitment portion includes a central opening having a central portion and a rearward portion open to the rear end, and configured to receive a post of a tool clamping mechanism. The fitment portion further includes a first plurality of openings in communication with and extending radially outward from the central portion, a second plurality of openings not in communication with and positioned radially outward from the central portion. The central portion, the first plurality of openings, and the second plurality of openings are configured to couple the fitment portion to a plurality of different configurations of attachment mechanisms for oscillating power tools.

A cutting die for cutting a plurality of parts of an article of footwear from a bulk material. The cutting die includes a first cutting member that cuts a first part of the article of footwear from the bulk material. The cutting die also includes a second cutting member that cuts a second part of the article of footwear from the bulk material. The second cutting member is fixed to the first cutting member to cut the first and second parts together with a single stroke of the cutting die relative to the bulk material. The first and second parts are separate and distinct from each other and have different shapes.

A saw blade includes a blade base with an arcuate cutting edge. The cutting edge is curved to a lesser extent than a circular arc with a radius that corresponds to the distance between the axis of rotation of the saw blade and the cutting edge.

A saw blade for a sawing machine for cutting micro trenches for receiving at least one duct or cable. The saw blade includes coding elements such as holes, depressions or protrusions. The holes, depressions or protrusions form at least one code symbol representing a unique identity (ID) for the saw blade.

A method for placing at least one duct/communication cable below a road surface in an area. The area comprises a first layer and a second layer, the first layer being a road layer, such as asphalt or concrete, and the second layer being a bearing layer for the first layer and being located below the first layer. The method comprising the steps of cutting a micro trench in the area through the first layer into the second layer, placing at least one duct/communication cable in the micro trench so that that duct/communication cable is placed below the first layer, and filling the micro trench so as to restore the road surface.
