Blade

The Blade is a submerged knife-edge ridge in Wakatobi, Indonesia, situated at the heart of the Coral Triangle. The formation is a narrow, flat-topped ridge running for over 150 metres, with some sections no more than six metres wide. Sheer walls drop off into deep blue water on both sides, creating a vertiginous, abyss-flanked profile unlike typical reef or wall dives.

The dive is a true one-way drift along the ridge, carried by current the entire way. The walls are covered with gorgonian sea fans and whip corals, all oriented to catch passing nutrients. Because the ridge is so narrow, buoyancy control must be precise throughout — drifting too high risks being swept over the top, while sinking too low means losing sight of the ridge altogether. The site is classed as advanced and demands superior buoyancy control and situational awareness.

Pelagic life is a constant feature at The Blade. Eagle rays glide in the current, dogtooth tuna patrol the edges, and schooling barracuda, trevally, fusiliers, reef sharks, turtles, large groupers, soft coral colonies, Napoleon wrasse, pygmy seahorses, and whip corals are all recorded at the site.
