is it though? lvl 1 abyssal razor will deal 300 damage to troll with a special attack (60*1.5+60*1)x2
while bronze spear lvl 1-4 will only deal 157-240 (lvl1: 52.5*1.5*2 , lvl4:79.5*1.5*2)

and it's way easier to get abyssal razor (so easy that it's usually my 1st dagger now) then to get fully upgraded bronze spear.

and even copper knife lvl1-4 will deal 180-225 damage. and it's also considerably easier to craft
