It's also worth noting that all the weapons with a DAMAGE rating of 30 or higher are capable of two-hitting players DEAD to their head with a heavy hit, making many of the common melee tools too powerful.
Brass knuckles, hammer, tire iron, pipe wrench, lead pipe, crowbar & bat are all low-tier melee weapons which deal at least 30 damage with a heavy attack and can two-hit players dead with headshots. These are common tools and deal too much damage since 1.11, the balance was generally much better in 1.10, other than the 1-hit KO of the sledgehammer and shovel.
