1. A chain saw comprising a housing, a chain comprised of links which include chain link mating elements and cutters, and an elongated support extending outward from inside said housing, in the outer surface of said elongated support there being present a continuous chain channel guide into which said chain link mating elements are slidably inserted, such that during normal operation said chain link mating elements slide essentially freely through said continuous chain channel guide, said continuous chain channel guide having a slit present therein which allows effecting an offset of said continuous chain channel guide from one side of said slit to the other, said offset, when present, serving to impede the slideability of said chain link mating elements across said slit, said chain saw further comprising an adjustable continuous chain channel guide alignment means for aligning the sides of said slit, said continuous chain channel guide being in an offset position, from one side of said slit to the other, unless a user causes it to be aligned by adjusting the continuous chain channel guide alignment means, thereby providing a chain saw which impedes the slideability of said chain link mating elements across said slit until said slidability is desired by a user. 2. A chain saw as in claim 1, in which the continuous chain channel guide alignment means is a dumbell shaped element slideably mounted in the elongated support, such that in use said dumbell shaped element causes alignment of the continuous chain channel guide from one side of the slit to the other, when caused to be located at said slit. 3. A chain saw as in claim 1, which further comprises a second slit in said continuous chain channel guide which allows effecting an offset of said continuous chain channel guide from one side of said second slit to the other, said chain saw further comprising a second adjustable continuous chain channel guide alignment means for aligning the sides of said second slit, said continuous chain channel guide being offset from one side of said second slit to the other, unless a user causes it to be aligned by adjusting the second continuous chain channel guide alignment means, thereby providing a chain saw which impedes the slideability of said chain link mating elements across said second slit until said slidability is desired by a user. 4. A chain saw as in claim 3, in which the continuous chain channel guide alignment means for aligning the sides of said second slit is a dumbell shaped element slideably mounted in the elongated support, such that in use said dumbell shaped element causes alignment of the continuous chain channel guide from one side of the second slit to the other, when caused to be located at said second slit. 5. A chain saw comprising a housing, a chain saw chain comprised of links which include chain link mating elements and cutters, and an elongated support extending outward from inside said housing, in the outer surface of said elongated support there being present a continuous chain channel guide into which said chain link mating elements are slidably inserted, such that during normal operation said chain link mating elements slide essentially freely through said continuous chain channel guide, said continuous chain channel guide having means present therein which effect an impeded chain channel guide, said means to effect an impeded chain channel guide serving to, when operated, impede the slideability of said chain saw chain in said continuous chain channel guide, said means to effect an impeded chain channel guide comprising at least one slit laterally thereacross, said chain saw further comprising an adjustable continuous chain channel guide alignment means for aligning the sides of said slit;said chain channel guide being in a position selected from the group consisting of:continuous from one side of said at least one slit to the other, andoffset from one side of said at least one slit to the other,unless a u ser causes the channel guide on each side of said at least one slit to be positioned as:offset from one side of said at least one slit to the other, andcontinuous from one side of said at least one slit to the other,respectively, by adjusting the continuous chain channel guide alignment means. 6. A chain saw as in claim 5, in which the continuous chain channel guide alignment means is a dumbell shaped element slideably mounted in the elongated support, such that in use said dumbell shaped element causes alignment of the continuous chain channel guide from one side of said at least one slit to the other, when caused to be located at said at least one slit. 7. A chain saw comprising a housing, a chain comprised of links which include chain link mating elements and cutters, and an elongated support extending outward from inside said housing, in the outer surface of said elongated support there being present a continuous chain channel guide into which said chain link mating elements are slidably inserted, such that during normal operation said chain link mating elements slide essentially freely through said continuous chain channel guide, said continuous chain channel guide having a slit present therein which allows effecting an offset of said continuous chain channel guide from one side of said slit to the other, said offset, when present, serving to impede the slideability of said chain link mating elements across said slit, said chain saw further comprising an adjustable continuous chain channel guide alignment means for aligning the sides of said slit, said continuous chain channel guide being in a continuous position, from one side of said slit to the other, unless a user causes it to be offset by adjusting the continuous chain channel guide alignment means, thereby providing a chain saw which allows the slideability of said chain link mating elements across said slit until impedance thereof is desired by a user. 8. A chain saw as in claim 7, in which the continuous chain channel guide alignment means is a dumbell shaped element slideably mounted in the elongated support, such that in use said dumbell shaped element causes alignment of the continuous chain channel guide from one side of the slit to the other, when caused to be located at said slit. 9. A chain saw as in claim 7, which further comprises a second slit in said continuous chain channel guide which allows effecting an offset of said continuous chain channel guide from one side of said second slit to the other, said chain saw further comprising a second adjustable continuous chain channel guide alignment means for aligning the sides of said second slit, said continuous chain channel guide being continuous from one side of said second slit to the other, unless a user causes it to be offset by adjusting the second continuous chain channel guide alignment means, thereby providing a chain saw which allows the slideability of said chain link mating elements across said second slit until impedance thereof is desired by a user. 10. A chain saw as in claim 7, in which the continuous chain channel guide alignment means for aligning the sides of said second slit is a dumbell shaped element slideably mounted in the elongated support, such that in use said dumbell shaped element causes alignment of the continuous chain channel guide from one side of the second slit to the other, when caused to be located at said second slit. 11. A chain saw as in claim 9, in which the continuous chain channel guide alignment means for aligning the sides of said second slit is a dumbell shaped element slideably mounted in the elongated support, such that in use said dumbell shaped element causes alignment of the continuous chain channel guide from one side of the second slit to the other, when caused to be located at said second slit.
