The Plasma Chainsaw is a mower in the "saws" class of mow my lawn default shop. It appears to be a black and red chainsaw with a blade wreathed in red plasma. The head, body, and plasma storage drum could possibly be made out of special carbon (Manlinite). It is a very powerful mid-class mower.
The Plasma Chainsaw costs 100 trillion Trimmings, and is located in the saws category of the default shop interface. It has the icon of a normal chainsaw, but with a red sun underneath it. This could be thought to represent plasma.
Using the plasma chainsaw nets the user 20 billion trimmings per part mowed, and has a one in 750 chance to grant the user a player point while mowing. It can be considered one of the most powerful medium-class mowers. Other than this, it possesses no other special abilities.
While the mouse-over description of the tool claims the plasma chainsaw is at around four trillion degrees Celsius (Centigrade) hot, the hottest plasma ever created by man is at a mere 3.6 billion degrees Fahrenheit, or around 2 billion degrees Kelvin.
