Zed doesn't build Stormrazor second.
He doesn't even build it at all anymore, especially not as it's now nerfed down to only a 140% crit without crit chance.
"Yes he does the one in my last ga-"
Don't even try.

All of this combined with his ultimate, Electrocute, and maybe ignite, is enough to burst someone down with out a doubt
Sure if he is 8/0 and against an squishy with 0 armor.
There is no need for anymore damage if you just get a deadman's or a Sterak's, you can just live longer and dish out even more damage.
Yeah and then the enemies catches up, starts building armor and you just wasted your whole lead on tank items and suddenly can't kill anyone anymore. Epic.
It's better to just invest into
as first 2 items and a
after.
The Cleaver gives you enough survivability for a mobile Assassin's needs and lets you help your team take down tanks, a investment that's way better than just tankiness.
If you look at most Zed's, this is a common way to build him.
