As Drmixable mentioned, it is very situational. If you're intending to solely be a kill lane, it might make sense to go Sapphire Crystal, ward, health pot, then tears.If you do this, you are gambling completely on your lane getting first blood and then compounding that advantage into laning dominance for the rest of the laning phase.
If you are wanting to be a more traditional support early game, then definitely do the standard Faerie Charm, wards, health pots mix.
Even if you do start with the mana crystal and go straight into tears, I think it still makes sense to move towards the more traditional support build after you pick up the tears. Philo stone, Heart of Gold, lots and lots of wards, oracles, etc. Build your gp10 items into their upgrades, prioritizing Shurelya's if your team is winning team fights and Locket if they are not.
And - as always - buy boots on your second trip back to base. For Blitzcrank, Boots of Mobility upgrade later makes a lot of sense for getting into position to yoink someone or knock them up to protect your carry. However, if the team is full of hard CC you will of course want the tenacity from merc treads instead.
Other good items include getting an early catalyst(which will build into Banshee's later), to sustain your lane harass and increase your passive shield proc if necessary. An aegis, of course, is always welcome from a support. Frozen Heart could be viable if the enemy team has more than two sources of straight auto attack damage, but generally won't be worth it.
Hopefully this wall of text gets you started on the path to thinking about how to apply your items to each situation. There is no single item guide that any hero should follow. Anything from who you are facing, how much gold you have, and how late it is in the game can vary your items and the order you build them in.

It is NEVER worth it to "Solo" Baron (Unless you are full gear and kill him in a couple of seconds). Because:
- You waste lots of time doing it alone
- You can be easily ganked/killed
- After a small push you can call 2 or 3 teammates and do it quickly, so why do it alone? It's a team type game after all, right ?!
- Take a look at this link: When should I Baron?
But Michel, I really want to give it a try, so which champion is good
for it?
Basically Attack Damage based Champions:
Those 3 are the best for the service.
- Tryndamere has a huge amount of damage and his ult can keep him alive for extra damage.
- Vayne does True damage, and with enough attack speed and damage you will not have any trouble at all
- Kog'maw has good skill rotation, and he match really well with Madred blood razor.
Others good champions are:
- Gangplank
- Shaco
- Heimidinger
- Olaf
NOTES: At 15min you can do Baron between 15 and 30 seconds with 3 level 12 without much trouble, or even 2 if you two are fed as hell (bot style for the win). So go for it with a couple of friends and you will be fine. Care for wards (Oracle or pink ward here). Check out for the enemy invasion too.

Usually you don't want to buy boots of swiftness on any champion except on Singed or Hecarim but even for those two swiftness is very situational and it's usually better to buy Ninja Tabi or something like this.
Now another thing you should think about is: Can my champion really benefit from the stats on Zephyr? Of course Tenacity, CDR and Movementspeed are good on every champ but Attackspeed/AD isn't that useful on all bruisers.
But let's see where you can buy Zephir for extra movementspeed, Tenacity: 2 Champions that come to my mind that work actually pretty well with Zephyr are Udyr and Irelia. Both are Rather tanky, benefit from Attackspeed, AD, CDR and Movementspeed. But boots of swiftenss? The main problem with these boots are not that they are "bad" but that there are other boots that are far superior to them. If you take ninja Tabi for example you will get a good amount of base armor which is very strong early in the game and 10% damage reduction from basic attacks. This means you are negating a huge amount of damage coming from AD Based champions.
Recently riot also removed tenacity from the tank jungle item (Spirit of the ancient golem). This basically means that now there are only 2 Items on summoners rift that provide tenacity and only one of those two Items is viable on a lot of champions (This somehow sounds familiar to season 1 eh?). Unfortunately tenacity is a really important stat if the enemy has Hard-CC with a duration of 2 seconds or longer. So here a little overview of when to buy which boots. Bold Boots are a good option when buying a Zephyr on bruisers.
The thing with BoS and why they aren't that viable: They reduce the effectiveness and not the duration of a slow. If you are slowed for 40% you will lose 10% on that slow but you are still slowed by 30%. This is still a huge slow when playing the game.
A correct boot choice is important!
