Quick Answer: Fishing lures are made through various industrial processes including plastic injection molding, metal stamping, and hand-carving wood. They utilize materials like balsa wood, stainless steel, and soft plastisol to mimic the movement and appearance of natural prey.

The Foundations of Lure Design

Before a lure ever hits the water, it begins as a concept focused on specific underwater physics. Different lures target different senses. Some rely on visual triggers, like bright colors or flash. Others rely on lateral line stimulation, which is how fish "feel" vibrations in the water.

For a practical look at lure materials, read what fishing lures are made of.

Understanding the Categories

Lures are generally categorized by their action and the depth at which they operate.

• Spoons: These are the oldest and simplest designs. They are curved metal plates that wobble to mimic a wounded baitfish.
• Spinners: These feature a metal blade that rotates around a central wire, creating a high-frequency vibration and significant flash.
• Plugs: These are hard-bodied lures, often made of wood or plastic, shaped like minnows, frogs, or crawfish.
• Soft Plastics: These are flexible lures made from synthetic polymers that feel realistic to a fish when they bite.

Materials Used in Manufacturing

The choice of material determines the lure's buoyancy, durability, and action. While modern manufacturing has shifted toward synthetics, traditional materials like wood still hold a premium place in the market.

Key Takeaway: The material of a lure dictates its "action." Wood offers a natural, erratic movement, while plastic provides consistency and durability for repeated casting.

How Hard Plastic Lures Are Made

Most modern hard baits, such as crankbaits and poppers, are produced through a process called injection molding. This allows for high-volume production with incredible precision.

The Injection Molding Process

Manufacturers use Acrylonitrile Butadiene Styrene (ABS) plastic pellets. These pellets are melted and injected into high-pressure steel molds.

1. Molding: The lure is usually molded in two symmetrical halves. This allows the manufacturer to place internal components inside before sealing.
2. Internal Hardware: Before the halves are joined, "rattles" (small steel or tungsten beads) and weight transfer systems are added. These help with casting distance and sound.
3. Ultrasonic Welding: The two halves are fused together using high-frequency ultrasonic vibrations. This creates a waterproof seal without the need for heavy adhesives.
4. Painting and Finishing: Lures are then primed and painted. Many high-end brands use automated sprayers for base coats and hand-painting for fine details like scales and eyes.

The Craft of Wood Lures

Wood lures, particularly those made of balsa or cedar, are prized for their unique buoyancy. Because wood is a natural material, no two lures swim exactly the same. We often see these featured in our more advanced kits because they require a higher level of finesse to use effectively.

Shaping and Carving

Commercial wood lures are often turned on a CNC lathe to ensure the basic profile is consistent. However, the finishing work is almost always done by hand. Balsa is extremely soft, making it easy to shape but difficult to protect.

If you are interested in the hand-tool side of this work, browse the BattlBox bushcraft collection.

Sealing and Weighting

Wood is porous. If water gets inside, the lure will swell and the paint will crack. Manufacturers "dip" the wood bodies in nitrocellulose lacquer or specialized sealants multiple times.

Note: Internal weighting is critical in wood lures. Since wood is naturally buoyant, lead or tungsten weights must be precisely placed in the belly to keep the lure upright.

Making Soft Plastic Lures

The "rubber" worms and craws in your tackle box are made from a material called plastisol. This is a suspension of PVC particles in a liquid plasticizer.

The Pouring Process

1. Heating: The liquid plastisol is heated until it becomes clear and syrupy, usually around 350 degrees Fahrenheit.
2. Coloring: Dyes, glitter, and scents (like salt or garlic) are added to the hot liquid.
3. Molding: In mass production, the liquid is injected into aluminum molds. For DIY enthusiasts, it is often hand-poured into open-face silicone molds.
4. Curing: The plastic cools and solidifies quickly. Once removed from the mold, it is placed in water to finish the curing process.

Step-by-Step: Making a Custom Balsa Minnow

If you want to try your hand at lure making, a small balsa minnow is the perfect starting point. This process mirrors how many professional prototypes are built.

Step 1: Create a Template. Draw the side profile of your lure on a piece of cardstock. A 50mm (2-inch) length is a versatile size for many species. Cut out the template and trace it onto a 3mm-thick sheet of balsa wood.

Step 2: Bend the Through-Wire. Use 0.7mm stainless steel wire. Using wire-bending pliers, create a continuous loop that includes the front line-tie, the belly hook hanger, and the tail hook hanger. This "through-wire" design ensures that even if the wood body breaks, the fish stays connected to your line.

A compact Exotac ripSPOOL field repair kit can also support line, repair, and improvised fishing tasks in the field.

Step 3: Prepare the Internal Cavities. You will need two identical balsa halves. Use a small leather punch to create shallow circular recesses in the inner faces of the wood. These will hold your split shot weights.

Step 4: Assembly and Gluing. Place the wire frame and weights into one half. Apply a thin layer of water-resistant cyanoacrylate (superglue) to the wood and join the two halves. Use a clamp to hold them together, but be careful not to crush the soft balsa.

Step 5: Shaping and Sanding. Use a sharp craft knife to shave off the square corners. Once you have a rough "rounded" shape, switch to 240-grit sandpaper, then finish with 600-grit for a smooth surface.

A compact blade such as the Fox Knives Mini-TA can be useful for controlled carving and camp tasks.

Step 6: The Diving Lip. Cut a slot in the head of the lure with a fine saw blade. Insert a small piece of G10 circuit board material or clear polycarbonate. This "lip" or "bill" is what makes the lure dive and wiggle.

Step 7: Sealing and Painting. Dip the lure in a clear sealer to waterproof it. Once dry, you can use an airbrush or even simple markers to create your pattern. Finish with a high-strength clear coat to protect the paint from fish teeth.

Myth: A bigger diving lip always makes a lure go deeper. Fact: While lip size matters, the angle of the lip and the placement of the line-tie are equally important in determining the maximum depth a lure can reach.

How Metal Spoons and Spinners Are Made

Metal lures rely on weight and light reflection. Because they are often used in saltwater or harsh environments, the manufacturing focus is on corrosion resistance.

The broader Hunting & Fishing collection is a useful place to explore fishing-related tools and accessories.

Stamping and Plating

Spoons are made by stamping shapes out of sheets of brass, steel, or copper. A massive industrial press hits the metal with several tons of force, cutting the shape and "cupping" it in one motion.

• Polishing: The raw metal blanks are placed in vibrating tumblers with abrasive media to remove sharp edges.
• Plating: Many spoons are electroplated with chrome, gold, or silver to provide a high-reflectivity finish that won't tarnish in the water.
• Assembly: Split rings and hooks are added using specialized pliers.

Spinner Construction

Spinners are built on a central wire "spine." A weighted body (often made of brass beads) is slid onto the wire. A clevis—a small U-shaped metal bracket—is used to attach the blade to the wire, allowing it to spin freely as the lure is retrieved.

Physics and Engineering: The "Tuning" Process

A lure is useless if it doesn't "track true." If a lure leans to one side or spins out of control, it won't trigger strikes.

Center of Gravity

The center of gravity must be low. This is why weights are placed in the belly of the lure. If the weight is too high, the lure will become unstable. Commercial manufacturers use computerized balance testing to ensure every lure in a batch performs identically.

For a closer look at fishing hardware and weights, read this guide to setting up a fishing hook and weight.

Hydrodynamics

The shape of the lure's head and the surface area of its sides determine how much water it displaces. A flat-sided lure creates a tight, fast vibration. A round-sided lure creates a wide, rolling action.

Bottom line: Lure making is a balance between art and fluid dynamics; every curve and weight determines how the tool interacts with the water.

Survival and Field Repairs

In a survival situation, you might not have access to a factory-made lure. Knowing how they are made allows you to improvise.

• Improvised Spoons: A handle from a stainless steel spoon can be cut and drilled to create a highly effective lure.
• Wood Carving: Any buoyant wood can be shaped into a "stick bait." Even without a diving lip, a topwater "walk-the-dog" action can be achieved by rhythmic rod twitches.
• Paracord Lures: The inner strands of paracord can be tied to a hook to mimic the skirt of a jig or a small minnow.

FAQ

What is the best wood for making fishing lures?

Balsa wood is the most popular for its extreme buoyancy and "lively" action, but it is very soft and requires heavy sealing. Cedar and Basswood are excellent alternatives that offer more durability while still providing great natural movement in the water.

Why do some lures have a clear plastic lip?

The lip, also called a bill, acts as a diving plane. When you reel the lure in, water hits the lip and forces the lure downward while causing the lure to wobble from side to side. The size and angle of this lip determine how deep the lure will dive.

Are handmade lures better than factory-made lures?

Handmade lures often have a more "soulful" and erratic action because of the natural variations in wood, which can be more effective for finicky fish. However, factory-made plastic lures are much more durable, consistent, and can include internal features like rattles and weight-transfer systems that are hard to replicate by hand.

How do I make my lures last longer?

To extend the life of your lures, always dry them completely before putting them back in your tackle box to prevent hook rust. For wood lures, check periodically for cracks in the clear coat and seal them with a drop of superglue to prevent water from soaking into the wood.
