Our Technology

Technology - Terminology


    Our proprietary new coating bonds Titanium with a non-stick formula. Highly resistant to adhesives including tape, glue, Velcro® and natural adhesive substances such as sap. This is a durable micro ceramic coating that will not wear off – up to 100,000 cuts. It is 5X harder than Stainless Steel alone and will stay sharper longer.


    Titanium Bonded® is not painted or plated but a unique application of titanium, chromium, and nitrogen to the cutting blades. It penetrates the metal surface to create a permanent bond. It will not flake, blister, chip or peel. The patented Titanium Bonding process makes the surface three times harder than untreated steel providing a blade that cuts better and stays sharper longer.


    Titanium alloy is lightweight, corrosion resistant and incredibly strong. Titanium alloy also has a very high tensile strength, toughness and ability to withstand extreme temperatures. Cuda® uses Titanium alloy on select tools for added strength, without increasing the weight of the product.


    Aluminum alloys tend to be more flexible than steels so they allow for better and more creative designs. Though there are aluminum alloys with somewhat higher tensile strengths than commonly used steels, adding aluminum in mass provides strength and rigidity. Aluminum owes its excellent corrosion resistance to the barrier oxide film that is bonded strongly to its surface and that, if damaged, re-forms immediately in most environments. Aluminum alloy is the perfect material for marine-based tools.


    Tungsten carbide is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then fused together in a furnace. Cutting inserts made in this manner are up to five times stronger than steel with high impact strength for long-lasting performance. Tungsten carbide is the preferred material for parts that must withstand all forms of wear.


    Heat induction is a triple-heat process. First, the base steel is heated, then the steel supporting the blade edges and finally, the blade edges. This achieves up to a 62Rc. This triple-heat process is a precise heating technology to a specific area of the blades providing a stronger, longer lasting cutting edge.


    A fine-grained stainless steel, often used for medical devices and food processing. The carbon and chromium content of this steel give it a great degree of corrosion resistance, as well as strength and edge retention. The 4116 Stainless steel is the perfect marine-grade cutting steel given its combination of carbon and chromium content.


    Quality tools start with quality steel. The more carbon in the steel, the longer the life of the tool. Cuda® uses high carbon steel to ensure maximum rigidity for tough task. High carbon steel does need to be maintained.


    First, we make or knife blades from premium stainless steel, known for its rust resistance. Next, we polish the surface to a bright finish. Making the surface mirror-smooth reduces the exposed surface area, creating fewer places where corrosion can start. Next, we passivate the blades. Passivation forms rust-resistant chromium oxide below the outer surface to create a wall of defense against salt water. Finally, we treat the surface with or Titanium Bonded® process to increase hardness and defend it even more from the elements.


    Thru-hardening gives you a hard steel blade that will hold its edge, even after re-sharpening. This is superior to case hardening which only hardens the surface.


    A full-tang is where the blade is extended throughout the handle portion of the cutting implement. Full-tang is incredibly important due to the fact that it provides strength to the cutting blade and also supports a stronger and more rigid handle.


    Backbone refers to the thickness of the blade. The Cuda® backbone is the strength behind the cut. A thick backbone provides and unparalleled rigidity so the cut is as straight and true as intended. 


    All Cuda® fishing tools feature the “Cuda® Scale Pattern” handles. The scale pattern is important as it provides an incredibly secure and comfortable grip in all environments and conditions. The scales are semi-soft and channel water away from the hand.


    Micro-serrations are crucial when the material or substrate being cut is slippery. The micro-serrations allow the blades to grip the substrate with the serrations without perforating or tearing the material being cut. The micro-serrations provide controlled and pristine cuts.


    Some material requires a “sawing motion” vs. a slicing motion. Cuda® offers various serration patterns on our tools to provide you with the most appropriate blade for the desired cut.


    A synthetic material made from paper, linen or thick canvas impregnated with resin under pressure. Micarta® is extremely resistant to water, cold, heat, rot or corrosion, therefore it is a perfect material for knife handles.
