This is the quintessetial on-hit item, because it applies 50% of your damage, but full effects of the on-hit. So if your champs auto-attack damage is almost entirely based on on-hit effects (AP Teemo, AP Varus, AS Kog'maw, etc.) You're basically close to tripling your damage output.

I think the coolest synergy is with Gunblade, 6 autoattacks under the right conditions and it's off cool again, and you get lifesteal from all of it. Though Sanguine Blade is more straightforward.
