Diving Knives and Shears: Essential Tools for Underwater Safety

Knives and shears are important safety tools for cutting lines, nets and entanglements underwater. Choose corrosion-resistant materials and secure mounting options to ensure reliability when needed. Proper selection, training and maintenance make these tools effective without adding unnecessary risk.

What to look for in a diving knife or shear

Durable blade materials and protective sheaths prevent corrosion and accidental injury. Shears offer controlled cutting for entangled ropes or fishing lines, while knives provide multi-purpose utility. Consider blade shape, serration and handle grip for use with thick gloves and in low visibility conditions.

Selection and care tips

• Mounting: choose a secure, accessible mount on the leg, chest or console.
• Maintenance: rinse, dry and oil metal parts after use to prevent rust.
• Training: practice safe deployment and cutting techniques in controlled settings.

Occasional deals and clearance items can reduce the cost of quality tools; if buying refurbished, confirm blade condition and sheath security. A well-chosen knife or shear adds confidence and capability to your dive kit while contributing to safer responses in unexpected situations.
