❓ Frequently Asked Questions
Absolutely! Even recreational divers face entanglement risks from fishing lines, kelp, and debris. A dive knife isn’t just gear – it’s life insurance underwater. Safety should always be your top priority.
For saltwater diving, titanium wins hands down. It’s completely rust-proof and stays sharp longer. If you dive frequently in salt water, titanium pays for itself. For freshwater or occasional diving, quality stainless steel works great.
Yes, but only in checked luggage – never carry-on. Pack it securely in your dive bag and you’ll be fine. Most airlines allow dive knives in checked bags without issues.
A quality dive knife should last 5-10 years with proper care. Replace it when you notice significant corrosion, blade damage, or if the locking mechanism becomes unreliable. Your safety depends on it working when you need it.
