Abyssal Blade Tinker ?
Why is Abyssal Blade not picked up on late-game Tinker? With level three Rearm the Tinker can keep anyone stunned until he runs out of mana. This even goes through Black King Bar. Why do people not replace their Scythe of Vyse with this item late game, since it offers better lockdown (no movement, unlike hex) and goes through Magic Immunity?
