Introduction

You are standing on a remote riverbank at dawn, the mist rising off the water, and you reach into your tackle box for that one specific crankbait. You have probably noticed that some lures feel like hollow shells while others are heavy and dense, but have you ever wondered why? Understanding what fishing lures are made of is not just about trivia; it is about knowing how your gear will perform when a trophy fish strikes. At BattlBox, we prioritize gear that stands up to real-world abuse, and if you want to get expert-curated gear delivered monthly, lures are no exception. This post covers the specific plastics, metals, and natural materials used in modern lure manufacturing. Knowing these materials helps you choose the right tool for the water conditions and the species you are targeting.

Quick Answer: Most hard fishing lures are made from ABS plastic or polycarbonate, while soft baits consist of a liquid vinyl called plastisol. Metal lures typically use brass, stainless steel, or lead, and traditional plugs often utilize balsa or cedar wood for specific buoyancy.

The Foundation of Hard Baits: Engineering Plastics

When you pick up a hard-bodied lure, such as a crankbait or a topwater popper, you are usually holding a piece of precision-engineered plastic. If you want a broader primer on picking the right bait, our What Fishing Lure Should I Use Today? guide is a good next step. Manufacturers do not just use "any" plastic. They select materials based on density, impact resistance, and how well the material takes paint or chrome finishes.

ABS Plastic

Acrylonitrile Butadiene Styrene, or ABS, is the most common material for mass-produced hard lures. If you want a deeper look at species-specific lure choice, What's the Best Fishing Lure for Bass breaks down the options. It is a thermoplastic that is favored because it is incredibly tough and has a mid-range density. When you see a lure with intricate molded scales or gill plates, it is likely ABS. This material allows for thin-walled construction, which creates a large hollow internal chamber. These chambers are essential for adding rattles or weight-transfer systems that help you cast further into the wind.

Polycarbonate

If you have a lure designed to dive deep and bounce off jagged rocks, it is probably made of polycarbonate. This is the same material used in bullet-resistant glass and safety goggles. It is significantly more impact-resistant than ABS. You will often find polycarbonate used for the "lip" or "bill" of a crankbait even if the body is made of another material. This ensures the lure does not snap its diving plane the first time it hits a submerged boulder.

Butyrate

Butyrate, or cellulose acetate butyrate, is a specialized plastic used for its unique acoustic properties. It is softer than ABS and produces a distinct, low-frequency "thud" when internal rattles hit the walls. Many experienced anglers swear by butyrate lures in muddy water because that deep sound travels differently than the high-pitched "clack" of harder plastics.

Soft Plastic Baits: The World of Plastisol

Soft plastics like worms, craws, and swimbaits revolutionized fishing because they feel natural to a fish. For more gear built around the same mindset, browse our Fishing Collection. A predatory fish will often hold onto a soft bait longer than a hard one, giving you more time to set the hook.

What is Plastisol?

Most soft lures are made from plastisol, which is a suspension of PVC (polyvinyl chloride) particles in a liquid plasticizer. If you want a quick look at the lure types anglers rely on most, Must-Have Fishing Lures for Every Angler is a helpful companion read. In its raw form, it is a milky white liquid. When heated to roughly 320 degrees Fahrenheit, it "clears" and becomes a molten liquid that can be poured or injected into molds. As it cools, it solidifies into the flexible, rubbery texture we recognize.

Adjusting the Durometer

The "durometer" refers to the hardness of the plastic. By changing the ratio of resin to plasticizer, manufacturers can make a bait "super-soft" for maximum action or "saltwater-hard" to withstand toothy predators.

• Soft blends: Used for drop-shot worms or finesse baits that need to move with the slightest current.
• Medium blends: The standard for most bass lures.
• Hard blends: Used for large swimbaits or saltwater grubs where durability is more important than subtle movement.

Additives and Scents

Soft plastics are rarely just plastic. They often include: If color matters as much as motion, What Color Fishing Lure to Use for Every Condition is worth a look.

• Salt: Added to increase the weight of the lure and provide a flavor that encourages fish to hang on.
• Glitter: Provides "flash" to mimic the scales of a baitfish.
• Scent: Oils and amino acids are often cooked directly into the plastic or added as a coating.

Key Takeaway: The material of a soft bait determines its action; softer plastics move more naturally but tear easily, while harder plastics last longer but require more rod movement to animate.

Metal Lures: Weight, Flash, and Vibration

Metal lures are some of the oldest tools in an angler’s kit. They are valued for their durability and their ability to sink quickly into the strike zone. In many of our curated BattlBox missions, we include metal tools and lures because they are nearly impossible to break in the field. If you want the broader gear mix that fits that same rugged approach, our Hunting & Fishing collection is a strong place to start.

Stainless Steel and Brass

Spoons and spinners are typically stamped from stainless steel or brass. If you want a compact add-on kit that includes the same small essentials, the Exotac xREEL Roundabout Kit packs hooks, lures, and weights into one setup.

• Stainless steel is prized for its corrosion resistance, making it the go-to for saltwater environments.
• Brass is heavier and often used for the bodies of inline spinners. It provides a distinct vibration that fish can feel through their lateral lines.

Lead and Tungsten

For weighted lures like jigs, lead has been the standard for decades. It is cheap, easy to melt, and heavy. However, modern anglers are increasingly moving toward tungsten. How to Set Up a Fishing Hook and Weight is a useful companion if you want to see how those weights play into a rig.

• Lead: Soft and inexpensive. It works well but is bulky.
• Tungsten: Much denser than lead. A 1/4-ounce tungsten weight is significantly smaller than a 1/4-ounce lead weight. This smaller profile helps the lure slip through thick weeds more easily. Tungsten is also much harder, meaning it transmits vibrations better, allowing you to "feel" the bottom more clearly.

Bismuth and Tin

In areas where lead is banned due to environmental concerns, manufacturers use bismuth or tin. These materials are non-toxic. Tin is lighter than lead, which gives a jig a slower "fall rate," keeping it in the fish's sight for a longer period. For anglers who also want to stay ready for the unexpected, the Emergency / Disaster Preparedness collection is a natural fit.

The Return to Tradition: Wooden Lures

Before the rise of the plastics industry, all "plugs" were carved from wood. Many professional anglers still prefer wood for specific scenarios because of its unique buoyancy.

Balsa Wood

Balsa is incredibly light and buoyant. A balsa crankbait has a "frantic" action that plastic cannot perfectly replicate. When you stop retrieving a balsa lure, it floats back to the surface rapidly. This makes it excellent for fishing around heavy cover, as you can let the lure float up and over submerged logs.

Cedar and Pine

Cedar is denser and more durable than balsa. It is often used for large topwater lures or "musky" baits. Cedar is naturally resistant to rot, which is a major plus for a tool that spends its life in the water. Hardwoods like maple or pine are sometimes used for heavy sinking lures where the weight of the wood itself helps with the casting distance.

Myth: Plastic lures have completely replaced wooden lures in professional fishing. Fact: Many "pro-grade" lures are still made of balsa because its high buoyancy creates a unique vibration that fish haven't grown accustomed to.

Component Materials: Hooks, Rings, and Skirts

The "body" of the lure is only part of the story. The components that connect the lure to your line and the fish to the lure are equally important.

Hook Materials

Most high-quality hooks are made of high-carbon steel. This allows the hook to be thin and sharp while maintaining its strength. A pocket-ready option like the Grim Workshop Bushcraft EDC Survival Card keeps fishing gear and small repair tools in one place. To prevent rust, they are coated in materials like:

• Nickel: The shiny silver standard.
• Black Chrome: Great for stealth and corrosion resistance.
• Tin: Often used for saltwater hooks to handle the salt's abrasive nature.

Split Rings and Swivels

These are usually made of stainless steel. They must be strong enough to keep a fish attached while being small enough not to ruin the lure's balance. When we select gear for us to use in the backcountry, we look for "heavy-duty" or "triple-wrapped" split rings to ensure a hardware failure doesn't cost you a meal.

Skirts and Tails

Lures like spinnerbaits or jigs often feature a "skirt."

• Silicone: The modern standard. It comes in thousands of colors and does not stick together in your tackle box.
• Rubber: An older material that has a very rhythmic, "pulsing" action in the water but can melt if stored in a hot tackle box.
• Bucktail: Actual hair from the tail of a deer. It has a natural "breathing" action in the water that synthetic materials struggle to match.

How Manufacturing Methods Affect Performance

The way a lure is put together can be just as important as the material itself. If you want a practical refresher on keeping your tackle organized, How to Store Fishing Lures pairs well with this section.

Injection Molding

Most plastic lures are injection molded. This involves forcing molten plastic into a precision-machined steel cavity. This process is incredibly accurate, meaning every lure that comes off the line will swim exactly the same way. This consistency is vital for anglers who need to know exactly how deep their lure will dive.

Hand-Pouring vs. Hand-Injecting

In the world of soft plastics, you will hear terms like "hand-poured."

• Hand-poured baits are made by pouring plastic into an open-faced mold. This allows for multi-colored layers (like a different colored belly and back) that look very realistic.
• Injection-molded soft plastics are usually more uniform and can be produced faster, but they often lack the subtle color layering of a hand-pour.

3D Printing

A newer entry to the field is 3D printing. While not yet common for mass production, many custom lure makers use 3D printing to prototype new designs. If you want gear that shows up ready to test, choose your BattlBox subscription and keep building from there. It allows them to test different internal weight distributions and shapes before committing to an expensive steel mold.

Choosing the Right Material for the Scenario

The material you choose should match the environment. If you are fishing a rocky river with high-speed current, a polycarbonate or metal lure is your best bet because it can handle the constant impacts. If you are in a clear, calm lake where fish are easily spooked, a balsa or soft plastic lure provides the subtle, natural presentation needed to trigger a strike. If you want a compact backup, the Exotac xREEL keeps small-fish capability in your pack.

Environmental Considerations

It is worth noting that the industry is shifting toward more sustainable materials. Many states now have restrictions on lead weights, leading to a surge in steel, tin, and tungsten options. Similarly, "phthalate-free" soft plastics are becoming the standard to ensure that if a lure is lost in the water, it has a minimal impact on the local ecosystem.

Durability in the Field

For those of us who view fishing as a survival skill or a primary outdoor activity, durability is king. A metal spoon or a thick-walled ABS topwater lure can last for years if the hooks are maintained. Wooden lures require more care; if the clear-coat finish cracks, the wood can absorb water, which ruins the buoyancy and action of the lure.

Summary of Lure Materials

Every material used in a lure serves a specific purpose. From the acoustic properties of butyrate to the high-speed "flash" of stainless steel, manufacturers balance physics and biology to trick fish.

1. Hard Plastics (ABS/Polycarbonate): Best for consistent action and durability.
2. Soft Plastics (Plastisol): Best for natural feel and slow presentations.
3. Metals (Brass/Steel/Tungsten): Best for depth, vibration, and flash.
4. Woods (Balsa/Cedar): Best for specific buoyancy and "hand-tuned" action.

Bottom line: Matching your lure material to your fishing environment is the fastest way to increase your catch rate and ensure your gear lasts through the season.

FAQ

What is the most durable material for a fishing lure?

Polycarbonate and stainless steel are generally considered the most durable materials. Polycarbonate is used for impact-heavy lures like deep-diving crankbaits, while stainless steel is the standard for spoons and spinners that need to resist corrosion and structural bending.

Why are some fishing lures made of wood instead of plastic?

Wooden lures, particularly those made of balsa, offer a level of buoyancy that plastic cannot easily replicate. This high buoyancy creates a faster, more aggressive "wobble" in the water and allows the lure to float over underwater obstacles more effectively than denser plastic alternatives.

Are soft plastic lures bad for the environment?

Traditional soft plastics were often made with phthalates, which can be harmful over time. However, most modern manufacturers have moved toward phthalate-free "eco-friendly" plastics, and many are even developing biodegradable options that break down if lost in the water.

What is the difference between lead and tungsten jig heads?

Tungsten is nearly twice as dense as lead, meaning a tungsten jig is much smaller than a lead one of the same weight. This smaller profile helps the lure sink faster and move through weeds better, while the hardness of tungsten provides better "feedback" to the angler when the lure hits the bottom.
