Titanium diving knives are the most durable and effective cutting tools available to scuba and snorkeling enthusiasts. They are strong enough to cut through tough fishing lines or hammer through an underwater lock. They’re also not a bad companion to have with you should a Great White or Mako drift into your dive zone. Below we have outlined your best options from the top manufacturers in this niche. “Arm Yourselves Mateys!”
