10 Best Dive Knife For Bcd 2026 in the United States

The Cressi Borg is a solid choice for a dive knife designed to be mounted on your BCD or leg. It has a total length of just over 10 inches, with a blade length around 5.5 inches, which is a good size for most diving tasks without feeling too bulky. The blade is made from 420 Japanese stainless steel, known for its toughness and corrosion resistance, which is important in saltwater environments. One side of the blade is straight-edged, ideal for clean cuts, while the other side is fully serrated, making it effective for cutting through tougher materials like ropes or nets. The pointed tip design is versatile, making it useful for precise cutting or poking if needed.

The handle is made from ABS plastic, offering a comfortable, ergonomic grip even when wearing gloves, and it has a small thumb tab that helps keep your fingers safely away from the blade. For mounting, the knife includes a sheath with a locking mechanism that allows you to release the knife quickly with one hand, and it comes with two standard straps to secure it to your leg. This setup is practical and common for divers who need easy access to their knife.

While the 420 stainless steel blade is good, it’s not the highest grade available, so it may require more maintenance to keep sharp and rust-free over time. Also, the sheath and straps are basic and might not suit all mounting preferences. The Cressi Borg performs well among dive knives for those who want a reliable, sharp, and versatile tool that combines straight and serrated edges, with a secure grip and decent mounting options. It suits divers looking for a durable, easy-to-use knife without extra features that might complicate its use underwater.

The TUSA FK-940 X-Ppert II Titanium Dive Knife is a solid choice for divers looking for a durable and reliable tool to attach to their BCD (buoyancy control device). Its 10-inch total length with a 4.5-inch blade strikes a good balance between manageable size and effective cutting ability underwater. The blade is made from Ti-6Al-4V titanium, a material known for its excellent resistance to corrosion, which is a big plus in saltwater environments where rust can quickly damage lesser knives. The drop point blade includes both a smooth edge and a serrated section plus a line cutter, offering versatility for different cutting needs like ropes or nets. The ergonomic grip design with a counterweight helps with handling, making it easier to retrieve and use underwater.

Mounting is straightforward with a single-button sheath lock release and adjustable straps for a secure, comfortable fit on your BCD. The handle material is titanium but the sheath is made of plastic, which might feel less sturdy to some users. While the knife has a modern look and good build quality, it is somewhat on the pricier side compared to basic dive knives. If you want a reliable, corrosion-resistant knife with versatile cutting options and easy mounting, this TUSA model is a strong candidate, especially for regular divers who value durability and comfort.

The Mares Force Plus dive knife is a solid choice for scuba divers needing a reliable and compact tool. Its 3.9-inch stainless steel blade, treated with a special coating, offers good resistance against corrosion—important for saltwater diving. The blade includes a built-in cutter, which is handy for quickly slicing through lines or ropes underwater. The knife’s ergonomic, soft handle ensures a secure, comfortable grip, even when wearing gloves, making it easy to use in tricky underwater situations. It’s designed to attach easily to Mares BCDs, bags, and hoses, so it stays accessible without getting in the way.

The blade size is on the smaller side compared to some other dive knives, which might limit its use for heavier tasks. For recreational divers looking for a dependable, easy-to-mount knife that covers basic cutting needs, the Mares Force Plus offers a good balance of durability, convenience, and functionality.
