    Abstract: The present invention is a rolling device for cutting sheet material including a planar body member supported vertically on wheeled axles oriented perpendicularly to the vertical planar body member. The planar body member includes a cutting notch and a contained cutting blade member with a cutting edge exposed within the cutting notch. A handle member is secured to the planar body member and extends upwardly opposite the wheeled axles. A crossbar can be attached to the handle member. A user grasps the handle member, or crossbar, and rolls the planar body member forward on the wheeled axles to cut a sheet of material passing into the cutting notch.

    Abstract: An opener for envelopes that includes a flat member with a straight slot that defines a pointed portion to facilitate its insertion between the flap and the rest of the envelope. A bay at the end of the slot coincides with the cutout of a removable blade kit that is received within a channel that runs at an angle with respect to the straight slot. A locking protuberance and a cooperating cavity are provided to keep the blade kit in place.

    Abstract: A tool for obliquely severing flower stems comprises a housing having a passage for inserting thereinto a flower stem to be severed, and a cutting blade extending between the opposing side walls of the passage. The cutting edge of the cutting blade is directed in the inserting direction and obliquely towards a bottom wall of the housing. A spring blade is mounted to the bottom wall of the housing. The cutting blade is mounted relative to the spring blade in such a way that the cutting blade and the spring blade are at a minimum distance from each other in a non-use condition but are permitted to be pushed apart against the action of a slight force of the spring blade when a stem to be severed is inserted into the passage.

    Abstract: An implement is provided for opening letter envelopes comprised of a body defining a handle and an envelope receiving crevice of a predetermined width and length. A blade is disposed within the body and has a cutting edge directed toward the crevice. A guide within the body limits movement of the blade to a linear path between a position wherein the cutting edge projects into the crevice in the direction of the width thereof and a position wherein the cutting edge is withdrawn from the crevice. Guides within the body control the position of the blade along the path and a manually operable slide is provided for external actuation. A dial is eccentrically mounted on the body in the path of movement of the slide and is rotatable to adjustably limit the extent of projection of the cutting edge of the blade into the crevice. The dial prevents the blade from spanning the crevice entirely.

    Abstract translation: 提供了一种用于打开信封信封的装置，该封套由限定手柄的主体和容纳预定宽度和长度的缝隙的信封构成。 刀片设置在主体内并且具有朝向缝隙的切削刃。 主体内的引导件将刀片的运动限制在切割边沿其宽度方向伸入缝隙之间的位置和切割边缘从缝隙中撤出的位置之间的线性路径。 身体内的引导件控制刀片沿着路径的位置，并提供可手动操作的滑动件用于外部致动。 拨盘在滑块的运动路径上以偏心的方式安装在主体上，并且可旋转以可调节地限制叶片的切割刃突出到缝隙中的程度。 表盘防止刀片完全跨越缝隙。
