  • Patent number: 9994067
    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.

  • Patent number: 9975261
    Abstract: A culinary tool (100) suitable for both cutting and transporting food includes a tool member (101) and a handle (108). The tool member (101) begins at an asymmetrical base region (102) and tapers along a major face (103) of the tool member (101) to a distal tip (104). A curvilinear medial ridge (105) begins at the asymmetrical base region (102) and passes along the major face (103), thereby defining a cutting portion (106) and a spatula portion (107). The cutting portion (106) sometimes the distal tip and occupies less of the major face (103) by area than does the spatula portion (107). The handle (108) is affixed to the tool member (101) along the asymmetrical base region (102). The culinary tool (100) can be used in either a cutting mode or a spatula mode.

  • Patent number: 9975269
    Abstract: A power table saw has a saw blade driven by a motor with power selectively supplied to the motor by actuation of a switch. A riving knife is selectively positioned in an extended position and a retracted position relative to the blade. A blade guard is removably mounted to the riving knife above the blade. A sensible element on the riving knife can be detected by a first sensor when the riving knife is retracted, the first sensor has a non-null state when the sensible element is adjacent the first sensor and a null state otherwise. A second sensor has a null state when the blade guard is detected and a non-null state otherwise. A controller determines the states of the sensors and disengages power to the motor when the switch is actuated when the states of the sensors are different.
