A Chainsaw is the worst weapon to use in a zombie apocalypse.

Thank you, Ore_Ele, for accepting my first formal Internet debate. Before I begin, the chainsaw I speak of is two-handed, or what a logger would use[0]. Now, I am going to attempt to bring to light why the chainsaw is the worst weapon for the zombie apocalypse, I will make rebuttals against your analysis of the Kershaw Select Fire next round. I will begin by stating the disadvantages it has as a weapon, then make a small scenario for both its use against a single zombie (As I specified in the beginning post), and then a horde. The definition of a chainsaw, as provided by Merriam-Webster [1]: a portable power saw that has teeth linked together to form an endless chain 1. The Chainsaw is not designed for human flesh, it is designed for chopping down trees. I feel I don't need to provide proof for this, as it's common knowledge. Unlike a tree, a human (Or a zombie), has sinewy muscles, intricate threading of veins, bones, taking in to account that the blades are jagged, this would, despite the running speed of the blades, make it more likely to get caught within a zombie as you slowly saw through it. 1a. Even if you were to, say, sharpen the jagged blades, they are small, and again, using a chainsaw against a person or zombie is more than likely going to cause severe damage to the tool. Trees are hard, and usually dry. The human body is not. 2. A chainsaw is a slow-to-operate weapon. Lifting a chainsaw and slowly dropping it down is undesirable for any scenario. As a weapon, it can be used for either thrusting or slicing, but doing either of these will require some serious patience. Again, I bring up my first point, this isn't made for use against humanoids. So, contrary to what video games or movies may depict, this would take serious, valuable life-or-death time. 3. Let's take the typical walking zombie. The universal method in which a zombie changes a person is via their bodily fluids getting in your system. By biting you, a zombie is transmitting the virus, from their blood, to yours. This weapon definitely wouldn't create a clean kill. Considering the sawdust that flies about from this tool's proper use, it's easy to say that blood would be flying from the high acceleration from the blades. 4. The potential dangers of using a chainsaw as a weapon are quite high. A typical logging operation allows for proper stance, but in the scenario of a zombie apocalypse, to ensure a kill, one would have to lift and swing a running chainsaw. There is the potential to cut or jab yourself on the teeth during a wind-up. Also taking in to account the potential ear damage, one would either have to sacrifice most of their hearing ability by getting proper protective gear, as is recommended when purchasing (Or, in this case, finding) a chainsaw. [2] 5. The noise. Most chainsaws are gas-operated, one of these being on and active results in a loud running noise, that is constant, until the chainsaw is off. Zombies operate on hearing[3], so a chainsaw would be a dinner bell, so to speak, a loud beacon that lets them know where a human or group of humans are at. Unlike a firearm, this noise is constant, you cannot "tap-fire" a chainsaw, it is either active, and ready to be used as a weapon, or it is not. 6. Its design is not made for this scenario. This is always a two-handed weapon. there is little versatility in regards to stance, or usage. You are stuck either swinging, or thrusting. Unlike, say, an axe. With an axe, you are able to thrust with either end, chop, use the entire handle to push or protect, with ease. This simply isn't the case with the chainsaw. The average chainsaw is about 10.6 pounds, not including the chain and rod. (Unfortunately, I cannot find the source in which I read this, again.) 7. Even if one were to get a kill with a chainsaw, there would be all sorts of things now caught in the already short teeth, in an urgent situation, one kill would be all a person could get. Now, on to the scenarios I have set in the rules. Against a single zombie, a chainsaw is just too much trouble, and no benefit. If there were a zombie in the way, and he wasn't yet alerted to my presence, I would have to rev up the chainsaw multiple times, the roar of the engine alone would catch the zombie's attention, who would then begin walking towards me. I have already created a radius of sound for myself, and I have potentially just attracted every zombie in the area. A zombie is not killed unless connection to the brain is destroyed. This could be by destroying the brain itself, or chopping off the head[4]. So, I would have to either raise the chainsaw neck-level, and attempt to accurately swing it in just the right time spacing, or, I would resort to sawing through his entire torso. If the chainsaw stalls, I am now unarmed. Again, I bring up that the chainsaw is not designed with our muscles, flesh, and bones in mind. And, with the chainsaw caught, I am now susceptible to a bite. Assuming I got the kill, there would be the threat of the horde. I have already established that use against a single target is dangerous, inefficient, and foolish. Against even more zombies, I would be leaving myself entirely exposed as I saw through one zombie, slowly, and inefficiently. Assuming I got one kill, blade maintenance would instantly be required, as I stated in point seven. I would have a useless weapon in my hands after that, and all the space a zombie would need, would already be closed. [0] http://www.ebay.com... [1] http://www.merriam-webster.com...
