        欧美三级-Best Stainless-Steel Knives

        一本道高清幕免费视烦-Best Titanium Knives



        Sea water is extremely corrosive, and the salt eventually breaks apart just about any material it comes into contact with. Titanium however, is almost completely rust proof and corrosion resistant since it has no carbon to oxidise with the salt in sea water. Consequently, this high-quality material is however significantly more expensive than steel alternatives. It however requires minimum maintenance and is highly durable due to its flexibility.

        欧美BBwHD-Aqualung Agronaut

        This knife sits on the highest quality end of aqualung dive knives and is one of the toughest and best knives on the market. The two edges of the blade are split into smooth and serrated edge, giving the user options when cutting various materials.

The downside of this knife is the sheath and leg strap must be purchased separately.

                                                                                                        When choosing a dive knife, the deciding factor of the type of knife you will purchase is your primary use of it.

                                                                                                        Ideally, you want to purchase a knife which has a combination of both straight and serrated edges for maximum versatility in the use. The straight edge is great for cutting plastics including fishing line, trash, and similar. The serrated section of your knife is better suited for sawing natural materials including rope and kelp.

                                                                                                        Sharp Tips are designed for puncturing and cutting and are typically preferred by the spear fishing community. The downside of them is that they are sharp and can potentially cause more injuries, or damage equipment if they become unsheathed.

                                                                                                        Blunt Tips are better suited for digging, prying, and hacking which is more the behaviour you will be exhibiting as a scuba diver. The blunt edge means the knife is generally safer to handle than the sharp counterpart.

                                                                                                        Line Cutting Notches are a handy feature of your dive knife as it is a quick and sure way to free yourself from entanglement from fishing lines and small ropes with little effort.

                                                                                                        Metal Handles are great for grabbing your buddy’s attention when you bang them on your tank, however they are less comfortable to hold and can potentially slip out of your hands.

                                                                                                        Black Blades look fantastic and are virtually invisible to marine life. The downside of them, is if you drop a black blade, it might become virtually invisible to you too making it more difficult to find.

                                                                                                        Ergonomic handle is important in your handling comfort and quick grip access so make sure to test out how the knife feels in your hand before purchasing it.

                                                                                                        一本道高清幕免费视烦- What attachment is best for your dive knife?

                                                                                                        When scuba diving, you will either have a knife that attaches to your leg, equipment, or potentially one which you keep in your pocket. Larger dive knives are typically better suited on leg straps, while more compact ones can be smoothly attached to your BCD or air hoses. The most important part about the location of your knife, is that you should be able to reach it easily with either hand.

                                                                                                        BCD or Hose mounted knife have the benefit of being securely attached to your gear and require minimal effort to remember to bring with you on your dive. These knives are typically smaller, more compact, and lighter. You do however have to remember to remove them and clean them separately from your gear to ensure they stay sharp and rust free.

                                                                                                        Leg mounted dive knives can be more cumbersome and potentially cause entanglement issues, however many divers and free divers opt for them due to their size and feeling like Tomb Raider.

                                                                                                        Foldable dive knives have the benefit of being smaller and a great option if you wish to store it in your BCD pocket. They are also potentially safer as they cannot become unsheathed and hurt someone without being purposefully clicked open.

                                                                                                        If you already have a Scuba Diving Knife or you just bought one, leave a comment in the comment section below and share your experience with it.
