Sawblade is a power up in the game Fun Run. The sawblade is a throwable projectile that bounces on walls and rocks, and kills anyone who encounters it, including the thrower. The sawblade will not harm someone if they have a heart or shield active. The sawblade lasts for six seconds before disappearing.
There are instances in which a sawblade will discontinue rotation and movement as if frozen in place as the momentum siezes. During this occurance, a player may still be killed by the the inactive sawblade, by running into it.
