Fixed blade dive knives are the go-to choice for spearfishers. Why? They have awesome advantages!

  • Strength and durability.
  • Easy access in emergencies.
  • No complicated design and no mechanical components for easy cleaning and maintenance.
  • Versatile tasks like prying, digging and scraping underwater.
  • A secure grip handle made from one piece of metal or plastic – less chance of slipping out of your hand.

These benefits make it easy to see why fixed blade dive knives are the top pick!


Fixed blade dive knives have drawbacks. Safety is one. An exposed blade makes them harder to handle and store. Maintenance is another. Fixed blades need more care to avoid rust and corrosion than folding knives. Bulkiness is the third. Folding knives can be tucked away or attached to gear, while fixed blades are bulkier.

However, fixed blade knives are more reliable and durable. They have less moving parts, so they’re less likely to break or malfunction. When choosing a dive knife, it comes down to personal preference and use case. It’s important to find a blade and handle that fit comfortably and securely, and practice safe handling and storage techniques. Studies can support these points to make the argument more authoritative. As an editor, it’s important to ensure that the text only talks about the disadvantages of fixed blade knives without any tangents.


Now that we’ve explored the pros and cons of both folding and fixed blade dive knives for spearfishers, let’s take a closer look at how they compare in three key categories: price, durability, and ease of use. By examining the differences between these two types of knives in these areas, we can gain a better understanding of which type of knife is the best choice for different scenarios and spearfishers of different experience levels. So, let’s dive in and assess each sub-section in detail.


When considering dive knives for spearfishers, price is key. Folding knives are cheaper, making them a great choice for beginners or those on a budget. But they may not be as strong as fixed blade knives and need more care over time. Fixed blade knives are more costly, but they are also tougher and dependable – an investment that will last for many dives.

It’s important to think about the pros and cons of each type and decide which is best for you and your wallet. Tip: Buy a quality dive knife – it’s an essential tool for safety during a dive.

According to the Divers Alert Network, a dive knife’s blade should be made of rust-resistant stainless steel and should have a sharp tip and serrated edge for versatile use. It should also have a handle that fits comfortably in your hand and should come with a locking mechanism or sheath for safety. Remember that a dive knife is not a weapon, but a tool for emergencies such as entanglement or cutting fishing lines.


When selecting a dive knife for spearfishing, durability is key. Fixed blade knives are often tougher than folding knives since they have fewer parts. This makes them great for heavy tasks like cutting thick ropes or filleting fish underwater. Fixed blades are bulkier, but their strength and sturdiness make them the go-to choice for divers who need resilience.

Folding knives, on the other hand, are more portable, making them popular for those who prioritize mobility. But due to their design, folding knives are more prone to wear and tear. Although fixed blades are usually more reliable, some folding knives can be just as durable – provided they are of good quality and meant for heavy usage. Thus, it is important to pick a dive knife that can handle the tough conditions of spearfishing.

Pro tip: always opt for reputable brands to find a strong and safe dive knife.

Ease of Use

Divers have two main options when looking for ease of use in a dive knife for spearfishing: folding and fixed blade knives.

Both have pros and cons, appealing to different types of divers.

  • Folding knives are great for travellers or those wanting to store them in a BCD pocket. Plus, the blades can be folded away when not needed. But, they’re often smaller, making them less efficient for larger jobs underwater. Also, the locking mechanisms can be tricky to operate with cold or wet hands.
  • Fixed blade knives boast larger and stronger blades, plus better durability than folding knives. Yet they can be bulky to carry and store. Plus, exposed blades require more caution when handling above water.

It comes down to personal preference. Consider factors like dive style, typical dive site conditions, and comfort with different knives before deciding.
