Try to save up ~1500 gold to get your shoes and soulstealer before going back out there. It's absolutely necessary to get these before level 6. Once you get to level 6 and ~1500 gold head back and get your soulstealer. Immediately afterwards find your opponents that are in the most vulnerable position and then come from behind, use your q, let them try to run, then exhaust, shunpo, ultimate. Ignite and bouncing blades again if necessary Boom dead. If theres two opponents make sure to shunpo on the next one right after you kill the first to make sure he can't run away. Don't overpersue as it usually isn't worth it and will lead you right into an enemy gank (or if you're dumb enough an enemy tower...note you can tower dive later, just now isn't the time especially after using your ultimate).
If you find yourself low on health before having enough to buy your first hexblade, go back and upgrade your shoes or buy two spellbooks (+40AP is huge before level 10). This will ensure your next kill.
I just recently started getting the gank shoes (+5 mobility). My reasons are this: late game you have to go back and buy gunblades/deathcap/whatever and you might miss out on the start of a fight. I find that I can run back to wherever I need just in time to either use my ultimate or avoid the fight with the +5 mobility added. The extra speed is HUGE as mobility is one of Katarina's biggest assets. Furthermore, they help with running away. Not gonna win one? Don't die for no reason, just shunpo/flash combo out or just shunpo out. If they don't hit you for 5 seconds they won't catch you. I guarantee it.
Next up is giant's belt because it's a precursor to your later item and you generally need the health at this point (right at or around 2nd ulti point). I generally get another hexblade after this to help with survivability before getting the crystal scepter. At this point you should be doing enough damage where you'll only need to go back in emergency situations or if you need to buy some items. After a fight, either jungle or slay minions to get your health back up.
Sit back, let your team initiate fights in the middle and then shunpo in, unload your blades, and shunpo out. Get your gold up and go back and get your crystal scepter. From here on out, you'll be unstoppable. No one will be able to run away from you or your teammates once you get this item.
It should be getting towards the late game. It's expensive to upgrade those hexblades (~2500) a piece, but after each upgrade you'll notice the difference. Your ultimate will be doing so much damage that the other team will be screaming "OP OP OP" at you. That's why I call this the OP build. Just don't forget to use the actives on them, they help immensely to the point where you can even initiate fights and the other team will just run away as you shunpo after them in pursuit. By the time you have both, even your bouncing blade will be ridiculously overpowered since it is multiplied by both AP and AD(doing 2000+ damage a toss with all the hits combined).
