Definitions
- This invention relates to a cutting tool.
- this invention relates to a tool for cutting articles in a pre-determined manner and/or a horticultural cutting tool.
- Known cutting tools include knives and those that
- Variations include secados for cutting plants and wire cutters both of which are arranged for maximum leverage so the cutting ability of the tool increased.
- One problem with these tools is that it is difficult to cut articles such that all objects cut by the tool are cut in a reliably similar manner, or to cut objects in a non-rectilinear fashion.
- An object of the invention is overcome one or more of the above difficulties or at least to provide the public with a useful choice. Accordingly, in a first embodiment, the present
- invention broadly consists in horticultural cutting tool adapted for cutting an object such as a plant stem comprising at least two arms crossing at a pivot point, the pivot point dividing the arms into
- the cutting tool further comprising means for positioning and holding the object to be cut relative the tool.
- the positioning and holding means is a recess
- a horticultural cutting tool adapted for cutting an object such as a plant stem comprising at least two arms crossing at a pivot point, the pivot point dividing the arms into handle members rearward of the pivot point and operating members forward of the pivot point, at least one of the operating members being provided with or mounting a blade; the cutting tool futher comprising resilient means against which objects to be cut are pressed by the blade during the cutting operation.
- the resilient means is removable.
- the present invention broadly consists in a horticultural cutting tool adapted for cutting an object such as a plant stem comprising at least two arms crossing at a pivot point, the pivot point dividing the arms into handle members rearward of the pivot point and operating members forward of the
- the cutting tool further comprises gauge means for assessing the appoximate width of objects to be cut.
- the guage is formed integrally with the housing.
- the present invention broadly consist in a horticultural cutting tool adapted for cutting an object such as a plant stem comprising at least two arms crossing at a
- the pivot point dividing the arms into handle members rearward of the pivot point and operating members forward of the pivot point, at least one of the operating members being provided with or mounting a blade; wherein the cutting tool further comprises locking means to retain the cutting tool in a pre ⁇ determined position.
- the locking means comprises a locking member freely pivotable about a pivot point; the locking member, in a locking position, abuting a lip on one of the operating members, preventing the arms of the tool from moving away from each other; and in an unlocked position, pivoting away from the lip to allow the arms to move away from each other.

- Figure 7 is a plan view of a first embodiment of a cutting blade and blade head for use in the cutting tool of figure 1.
- Figure 8 is an end view of the cutting blade and head of figure 6.
- Figure 9 is an end view of the head of figure
- Figure 10 is a schematic view of a positioning
- Figures 1 to 3 illustrate a first embodiment of a
- the tool has two arms 110, 120, which cross at pivot point 130, to form two handles
- housing 180 which receives a blade head
- the blade head is preferably removable from the housing 170 either by the blade head being slidable
- the arrangement of the arms 110, 120 is such that if the handles 140, 150 are moved towards each other, the operating arms 160, 170 move towards each other.
- the second operating arm 170 abuts the blade 1 to provide for effective cutting of any article to be cut.
- operating arm suitably has a recess 220 for receiving objects to be cut.
- recess 220 for more efficient cutting of the article the recess 220 is
- the recess 220 may be lined with a resilient material 240 in which the blade
- receiving recess 230 is formed, such as rubber, plastic or sponge rubber etc.
- an article to be cut may be positioned in the recess 220, and when the handles 140, 150 are brought
- the cutting tool is preferably biassed towards an
- the cutting tool 100 is also preferably provided with a gauge 250 for assessing the width of objects to be cut.
- the gauge may be a sliding gauge or may simply be a plurality of recesses 260 of different widths as shown in figure 3. Objects to be cut which fit within one of the recess 260 are most suitable for use with the cutting tool 100.
- the widths of the objects (stems) may be quickly ascertained to find objects (stems) of matching width.
- the head 190 is pivotally mounted to the operating arm 160.
- a suitable pivot or cam arrangement is shown in figure 4, in which the arm 190 has a projection 270 which is received by a recess 280 (see figure 6) in
- the top of the projection 270 is preferably rounded.
- the end of operating arm 170 may be bifurfurcated so that it may receive and support the end of operating arm 160.
- This arrangement allows the blade to move in a straight line towards an object to be cut and therefore prevents any shearing and consequent damage to the object (such as bruising) that might be caused, for example if the blade's path of travel subscribed an arc.
- the housing 180 is mounted on the operating arm 170.
- the housing protects the user from the blade when the tool is in an open position.
- the recess 220 is formed in the housing and the head 190 and blade 200 are slidable mounted in the housing 180.
- the housing must be open on its underside or must at least have an aperture to allow for movement of the projection 270, between an open and a closed position.
- This arrangement allows for a narrower recess 220 which will more firmly hold objects to be cut than the recess 220
- the recess positions and holds a stem to be cut, substantially preventing the
- the resilient lining 240 also avoids the concentration of force on discrete points on a not perfectly straight stem which, if no resilient lining were provided, would be pushed against the rigid edge of the recess 220 during the cutting operation and bruised.
- the recess 220 is also preferably shaped so that it can only receive suitable objects to be cut, for example stems, and not other objects, such as fingers; and is of a shape corresponding to articles to be cut, such as a semi-circular shape, in cross section.
- resilient lining is that the lining can be removed for easy cleaning, especially of the recess. This is useful because, through constant use, the recess can become clogged with residue from the articles being cut, for example with resin from stems.
- the housing 180 is angled relative the handles. This provides the advantage of giving the operating arm 160 and handle 150 better leverage on the blade head so that it is easier for a user to cut through objects in the recess 220, particularly tough objects such as stems of plants, and also results in a cleaner cut being made by the blade.
- the housing may be substantially the same width as the operating arms 160, 170 or may protrude either side of the arms 160, 170 to form a much larger cutting area (see figure 5). This larger head is very desirable as it allows for an elongate and deep recess 220 which provides for convenient and accurate placement and support of article to be cut.
- the recess 220 is preferably deeper that the width of the articles to be cut.
- the tool is desirably provided with a locking member 310 pivotable about a point 320.
- the locking member in a locked position abuts against a lip or lips 330 on the operating arm 170 and prevents the arms 140 and 150; 160 and 170 from moving away from each other and opening the
- the locking member should be such a length that it performs this locking function when the tool is not quite completely closed. In this way a squeezing of the handles 140,
- the locking member 310 is most suitably free moving about pivot 320 such that when the tool is
- the blade may be of any suitable configuration depending on the use to which the tool is put.
- the blade and blade head are suitably removable from the tool so that the blade may be replaced or sharpened when blunt or broken.
- the screw or equivalent at the pivot point 130 may be removed so that the arm 120 may be disengaged from the arm 110 (the operating arm 170 of which may partially surround operating member 160) and disengaged
- Disengagement of arm 120 then allows the head 190 and blade 200 to be removed from a preferably open or openable rear end 350 of the housing 180 (or forward end, but this would be more dangerous as the blade/head unit would exit blade first).
- the stems eventually grow together and the roots feed the desirable stem.
- scions and rootstocks When grafting procedures are being carried out, many thousands of scions and rootstocks may be grafted onto each other at one time. To ensure the success of the grafting process, the scion and the rootstock should be cut in a similar and matching manner, preferably at least partially on the diagonal, so that a large surface area of the scion stem and the rootstock stem will be in contact. These cuts are often made by use of a knife or secateurs and require a considerable amount of experience and skill to perfect. This is because incorrectly cut scions and rootstocks will not "graft" or grow together properly. Even when an experienced and skilled worker performs the cuts, the failure rate is still high, since the cuts in the scions and rootstocks must be a very good match to ensure good grafting. Even the known
- stems are preferably a straight line, a V-shaped or similar two- directional cut being preferred.
- Scions and rootstocks cut with the tool of the present invention will therefore have reliably, and reproducibly matching cuts. This will significantly increase the success rate of grafting operations.
- the cut made in a stem by the "tail" 380 of the blade is very important in a grafting situation, because it determines how much of the cut stem will be available for grafting onto another cut stem. If the tail 380 were straight, as indicated by line 390, smaller stems would suffer from a significantly
- the present invention therefore provides a means for creating cuts in objects, particularly complex cuts safely, reliably, reproducibly, at speed and with minimal damage to objects being cut.
- the blade may be cylindrical for cutting holes in objects.
- the head 190 and the housing are cylindrical for cutting holes in objects.
