Abstract
An envelope opener features a through slot defining a channel that is closed on three sides around an axis of the slot. A blade projects into the channel from a first closed side thereof to an opposing second closed side thereof, and lies in plane spaced from the closed third side of the channel that lies opposite the mouth. The third side of the channel is angled relative to blade, and the cutting edge slopes away from the first closed side of the channel toward the second closed side, whereby the cutting edge is closer to both the second and third sides of the channel at one end thereof than the other. At the other end, a radiused corner is provided between the third side of the channel and an exterior of the tool. A metal insert lines one or more sides of the channel for an improved wear life.
