This wiki has been updated 17 times since it was first published in February of 2019. With all of the gear scuba diving requires, it can quickly become a very expensive sport, especially for those just starting out who are often buying everything at one time. Along with BCDs and air tanks, knives are among the most essential items that every ocean explorer needs. They are a vital safety tool that can mean the difference between life and death if you get caught on something. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.

Editor's Notes

February 07, 2019:

It can be difficult to pick out the best dive knife, as there is not one perfect item. Compromise must always be made. A larger model is often a more useful tool, but can be annoying for some to carry. Titanium models offer the best rust resistance, but are generally very expensive and tend to lose their edge quickly. We did our best to consider all the features you might need in a dive knife, and then chose the models that made the least amount of compromises.
