12. The apparatus of claim 11, wherein the opening means comprises at least one spring.

13. A method, comprising the steps of: inserting a plant stem into a stem channel of a hand-held housing at a preselected angle; and causing a cutting blade to move within a blade channel within the hand-held housing to cut the plant stem at a preselected angle by pushing a thumb grip and a finger grip toward each other; wherein the preselected angle promotes healthy root growth and is not a perpendicular cut relative to a diameter of the plant stem; and wherein the hand-held housing is configured so that the cutting blade is not accessible to a finger of a hand when the cutting blade moves from an open position to a closed position when the plant stem is cut.

DETAILED DESCRIPTION OF THE INVENTION

(6) In accordance with the present invention, plant propagation can be accomplished by use of a hand-held device that holds and moves a blade or sharpened feature to cut a stem at a desired cutting angle to promote healthy root growth. The cut stem is cut at a desired blade angle and blade path. The action is repeatable and speeds up a manual method while also increasing worker safety by containing the blade and cutting motion inside the device.

(7) In an especially preferred embodiment, a piece of plant-matter is inserted stem-first into a stem slot which guides the stem into the device. To cut the stem, a blade held on a support is caused to slice through the stem at a desired cutting angle, such as 45 degrees, my manually actuation of the device.

(8) There are three different embodiments presently contemplated for this device.

(9) The invention will now be described in even greater detail by reference to an especially preferred embodiment illustrated in FIGS. 1-5. In the Figures and the following description, number designations indicate various features of the invention, with like number designations referring to like features throughout both the drawings and the description. Although the Figures are described in greater detail below, the following is a glossary of the elements identified in the Figures. 1 clone cutter 2 first mechanical grip 3 second mechanical grip 10 removable cover 12 spring 12C spring channel 13 lower angled stem slot 13A angle of lower angled stem slot 13 14 screw 14H screw hole 15 first finger hole 16 cutting blade 21 blade channel 25 second finger hole 132 upper angled stem slot 133A angle of upper angled stem slot

(10) In a first embodiment illustrated in FIGS. 1-3, which is contemplated to be a more permanent device, slots for a thumb and another finger are present in the parts shown in FIGS. 2 and 3 while cover 10, illustrated in FIG. 1, is designed to be removable (by removal of four screws) and contains a stem slot at a 45 degree angle. Another stem slot at a 45 degree angle is found in the body, anvil side (FIG. 3) which is aligned with the stem slot of the cover but spaced sufficiently apart so that a blade held by the body, blade side (FIG. 2) can pass between the stem slots of the cover and body, anvil side, thus cutting the stem at a 45 degree angle. As shown in FIG. 2B, the body, blade side contains a slot for holding a blade (not shown in FIG. 3) which is force fit into the slot, although it can also be retained by a mechanical means, such as one or more screws. The body, anvil side has two spring channels, which hold two springs, which are compressed within their channels by movement of the body, blade side toward the body, anvil side, when protrusions come into contact with the springs. FIG. 4 is a picture of a partially disassembled apparatus, as illustrated in FIGS. 1-3, in which the four screws from the cover have been removed, one spring has been removed, and one of two screws which hold the blade in place is visible, while FIG. 5 is a picture of the same apparatus with both springs in place and partly compressed due to action of the body, blade side forcing compression of the springs in the spring channels.

(11) An important aspect of the first preferred embodiment is that the blade, when the device is fully assembled and being operated, cannot cut a finger, because the blade is not exposed except when it passes through the two stem slots, and these slots are sufficiently deep and of a small enough opening size, that a finger cannot get into either one of them to be cut by the blade.

(12) In a second embodiment, the embodiment of FIGS. 1-4 is altered so that it is made disposable. In such an embodiment the blade and spring are not replaceable, and the blade may be secured by injection molding.

(13) In a third embodiment, the actuation of the blade into a blade channel (such as the two stem slots of the first embodiment) is accomplished by squeezing two handles toward one another, in an action similar to that of a wrist exerciser. In this embodiment the key difference is that use a palm and fingers, rather than simply fingers, to actuate the cutting action.

(14) Although the foregoing detailed description is illustrative of preferred embodiments of the present invention, it is to be understood that additional embodiments thereof will be obvious to those skilled in the art. Further modifications are also possible in alternative embodiments without departing from the inventive concept. For example, a blade or cutting device might be replaced by a laser.

(15) Accordingly, it will be readily apparent to those skilled in the art that still further changes and modifications in the actual concepts described herein can readily be made without departing from the spirit and scope of the disclosed inventions.
