BACKGROUND
During hunting or wildlife observation, it is often difficult and tedious to establish and maintain a post to observe wildlife. For example, setting up a tree stand often requires a person to climb in position himself or herself in a tree, wherein branches may obstruct the positioning of the tree stand. Alternatively, positioning a camera in a tree to observe wildlife present his own challenges. In addition to the camera being potentially obstructed by tree branches, the camera may also be difficult to position at a desired angle given variations in tree diameters and tree angles. Carrying and utilizing implements to trim such branches at such high elevations is extremely difficult. Should the person desire to set up a blind, tent or other concealing shelter on the ground, such shelters are subject to accidental collapse in response to high winds.

DETAILED DESCRIPTION OF EXAMPLES
FIG. 1 is a perspective view of an example trim saw 20. Trim saw 20 is configured to be easily handled and carried up a tree while in a closed state. Trim saw 20 is configured to be easily opened and closed using a single hand, allowing a person to maintain his or her grip upon the tree being climbed. Trim saw 20 comprises handle 22, blade 24, blade retainer mechanism 26 and tether 27.
Handle 22 supports blade 24 and includes a slot 30 into which blade 24 may be pivoted and received. Panel 22 houses and supports blade retainer mechanism 26. In the example illustrated, handle 22 comprises a molded polymer handle. In other implementations, handle 22 may have other configurations.
Blade 24 comprises teeth 32 configured to saw branches of a tree. Blade 24 is pivotally connected to handle 22 for pivotal movement between a received position such as shown in FIG. 6 and an extended position such as shown in FIG. 1. FIGS. 9-12 illustrate blade 24 in more detail. As shown by FIG. 12, teeth 32 have an aggressive bite to facilitate cutting of tree branches. As shown by FIG. 11, in one implementation, blade 24 comprises a first edge 34 having teeth 32 and a second opposite edge 36. The edge 34 including teeth 32 has a first width that is greater than the width of edge 36. In one implementation, blade 24 gradually tapers from edge 34 to edge 36. In another implementation, the transition in the thickness of the blade or width of the edges from edge 34 to 36 may be stepped or curved. Because the edge contain teeth 34 is wider or thicker than the back of blade 24, blade 24 is less likely to become pinched as the tree branch is cut and is collapsing upon blade 24.
Blade retainer mechanism 26 releasably retains blade 24 in the received or folded position shown in FIGS. 4 and 6. Blade retainer mechanism 26 comprises a single pushbutton 40 projecting from one side of handle 22. Pushbutton 40, upon being depressed, causes blade retainer mechanism 26 to release blade 24, permitting blade 24 to be pivoted to the extended position. In one implementation, depressed a pushbutton 40 permits blade 24 to be swung or flipped out of recess 30 to the extended position shown in FIG. 1. As a result, trim saw 20 is easily deployable by one hand while the person is hanging from a tree cutting undesirable branches or foliage.
FIGS. 3, 4, 5, 7 and 8 illustrate blade retainer mechanism 26 in more detail. The basic function of the saw 20 is controlled by the actuation of a large button 40 located the side of the saw 20 at the blade pivot. The button 40 is designed allow the blade 24 to open easily with one hand by holding the saw 20 with right hand and pressing with the right thumb. The button 40 can also be actuated with the left hand using the left index finger. The button 40 is sized and placed such that a single gloved hand can actuate the button. Spring force for the button is provided by a standard wave spring 42 to bias the button 40 outward.
Once the button 40 has been fully depressed, internally the “lock” component slides out of the blade allowing the blade to pivot into the open position under the aid of the torsion spring 44. The blade motion is halted by a feature in the handle. The blade 40 is fixed into the open position by the lock component returning into the blade when the button is released. It is important to note that once the blade has been actuated by pushing the button, the button may be released at any point and the saw will automatically lock. FIG. 3 illustrates the internals of the saw by removing one of the handle sides; the lock component 46 in the locked position and the blade stop feature on the handle.
Closing the blade 24 is accomplished by pressing the button 40, thus releasing the blade 24, and pivoting the blade 24 back into the handle 22. The button 40 may be released at any point once the user has begun to close the blade and the saw will automatically lock closed when the blade 24 has been moved into the closed position (shown in FIG. 6).
