Static Shiv is very much an ADC item.
Ionic Spark was meant to be Bruiser/Tank item. The thing was a lot of fun on Shen and Volibear.
Saying 'oh, we don't need Spark because we have Shiv' is pretty silly. It would be like saying that we don't need Wit's End because we have Abyssal Scepter. They're two completely different items with similar effects meant for different types of champions.
Blade of the Ruined King used to be a Bruiser item since it dealt magic damage OnHit. But then it got turned into a Ranger item to appease the almighty ADC overlord. Bringing back Bloodrazor with no AD and more focus on defense would make it unattractive to ADCs, but a solid choice on a tanky champion looking for one offensive item to keep themselves relevant.
One of the problems in League is the fact that if an offensive, auto-attack enhancing item doesn't get built by ADCs Riot throws up their hands and removes it or remakes it into something the Rangers would like. And that's a real shame. I think offensive itemization would be way more interesting if OnHit items were focused on mixed offense/defense and AD/IAS/Crit kept to the glass cannon side of things. That way both itemization paths would have valid strengths and weaknesses to consider.
