Abstract: There is provided a tool blade, comprising a backing strip particles of abrasive material and a binder layer of binding material which binds the abrasive particles along an edge of the backing strip, wherein the edge of the backing strip is pre-formed with teeth, on which the abrasive particles are bound by the binding material. A profiled cutting portion extends beyond the pre-formed teeth. The pre-formed teeth are shaped as generally triangular waves or are flattened at least partially along an upper edge on which the cutting portion is at least partially disposed. A method of making such a blade is also provided.

Abstract: There is provided a tool blade comprising a backing strip, binding material forming a binder layer, with discrete regions of binder layer formed as teeth along an edge of the backing strip, and abrasive particles bound to the backing strip by the binder layer, wherein each tooth is formed with a ductile region bonded to the backing strip, a crown and an intermediate region of thermal material disposed between the ductile region and the crown so as to absorb thermal expansion and contraction. The binding material powder is heated by laser beam to form a binder layer which binds the abrasive particles to the backing strip. The laser beam is used to form discrete regions of binder layer as teeth. The binding material is typically braze material.

Abstract: There is provided a method of making a tool blade, in which a backing strip is provided, binding material in powder form is cascaded onto the backing strip, abrasive particles are provided and the binding material powder is heated by laser beam to form a binder layer which binds the abrasive particles to the backing strip. The laser beam is used to form discrete regions of binder layer as teeth. The binding material is typically braze material. A blade made according to the method is also provided.

Abstract: A security locker is for securing articles externally on a vehicle. The locker comprises a locker having at least one opening facing the exterior of the vehicle when the locker is fitted thereto, wherein the opening provides access to the interior of the locker. A door is moveable between an open position in which the interior of the locker is accessible through the opening from outside of the vehicle when the locker is fitted thereto, and a closed position in which the locker is inaccessible. The locker includes locking device that, when activated, locks the door in a closed position to prevent unauthorized access to the locker, and when deactivated unlocks the door to enable access to the locker. An input device is operatively connected to the locking device, wherein the locking device is accessible from outside the locked vehicle and it deactivates the locking device when an identifiable code is entered to thereby allow keyless entry to the locker.

Abstract: A saw blade has teeth grouped with varying shapes or other characteristics, such as composition. Each tooth has a root and a head separated by a transition region forming a neck. The roots may be oversize in relation to apertures or slots preformed in the strip, so that the teeth displace and deform the material of the strip, as they are forced into the position shown. They may then be fixed in position by brazing.
