Daryl Lim –
This Apollo Sqr 50HRC knife is very lightweight but still feels sturdy underwater. It cut through old fishing line with no trouble at all on my last dive. The grip is comfortable even with thick gloves, but I wish the sheath clipped onto my BC more easily.

Nurul Aini –
How do I properly clean and maintain the titanium blade after diving in saltwater? I want it to last as long as possible.
Imran Hanafiah –
Hi Nurul, after each dive, simply rinse the knife thoroughly with fresh water and dry it before storing. Although titanium is highly corrosion-resistant, regular cleaning will help maintain the blade and handle in top condition for years to come.
Wei Zhang –
Happy with the overall performance—the blade is super sharp and the quick-release sheath is handy. Took it on several dives in Tioman and there’s no sign of rust. Slightly pricey, but quality is there.
