How to Make LARP Weapons

Live Action Role Playing is the term for LARP swords, or LARP Weapons. They are used in cosplay, gaming, and fantasy. They make wonderful costume swords as well.

These LARP weapons are made of high-quality materials that will last for years of roleplaying. Our LARP gear is of the highest quality and most safe weapons available today.Play-based roleplaying, cosplay, and LARP weapons are quite popular in Europe and the United Kingdom, with the trend growing even faster in the United States.

There are a lot of low-quality LARP weapons available on the internet. Many of these LARP weapons have low initial expenses, but the materials and workmanship are inadequately high. We provide extremely high-quality LARP weapons for incredibly low prices. Inferior LARP weapons will break down quickly and will not last after a few uses.

How to Make LARP Weapons

What are LARP weapons made out of?

The majority of the time, you’ll be dealing with a stiff, light core covered in closed-cell foam (such as pipe insulation.)

Back in the day, PVC pipe would’ve served as the core, but those “dinosaur swords” were extremely hefty. Carbon fiber is used most often nowadays because it is much lighter. You’re not swinging a baseball bat when you use this, so there are fewer injuries and faster combat because you’re swinging a VASTLY lighter weapon.

The simple “boffer” recipe consists of closed-cell pipe insulation (preferably in the 5/8′′ range, give or take) for striking (swinging) surfaces, possibly open-cell foam for thrusting tips, and covered with duct tape. It’s not difficult to construct a big batch if you follow the instructions carefully. It looks more like a pool noodle than anything else, and it’s simple to make. Older fans of the game were content with a basic foam mat on the floor, but more seasoned players constructed elaborate rooms out of couch cushions and sleeping bags. More experienced individuals will use various forms of closed-cell (EVA foam mats, camping pads, etc.) to create something more shaped, and they’ll employ weatherstripping and plastidip to make swept-hilt rapiers and snake-headed staves. You lose in terms of appearance when you do either of these things, but they’re generally less expensive and easier to repair. Also, if the game allows it and the tip is built with an open-cell design, you can execute point work (fencing, spears), which is a viable style.

The “professional top end” work being done now is a step up from the “advanced DIY,” with carved foam that’s been painted with latex. They need more care to prevent damage, and repairs take considerably more skill and materials, but they look amazing as a result. Some games have latex weapons restrictions in place, such as who is allowed to use them in general or a “no thrusting” condition.

Why use foam?

There are several alternatives when it comes to materials for your costume, especially if you want to create a sword. While cardboard or other poster-board alternatives are available, they have certain drawbacks. The sword would be flimsy, easy on the eyes, and liable to break, for example. Wood for your sword is another option, as some cosplayers have done before. Although this option may be too heavy or costly, it’s also difficult to work with if you aren’t familiar with wood carving and sanding.

Foam is the best material for a cosplay sword because of a few factors. Foam provides the sensation of weight in your grasp without being as heavy as wood. Foam is also easier to work with, regardless of experience or novice status. Finally, foam is an inexpensive option, so if you make mistakes, it will not be as expensive as wood. It’s also a lightweight material, making it easy to transport around at events or conventions.

What type of foam?

The first thing to consider when making a cosplay sword is the kind of foam used. While there are many foams on the market today, not all of them are suitable for creating a sword for your costume. There are two types of foam that are particularly good for creation of cosplay weapons.

Polystyrene Foam

The light weight, closed-cell foam used in this foam is simple to cut into the form of a sword. Its closed cell nature rather than open cell makes it more firm, which is ideal for a sword while the material’s durability ensures that it has long-lasting. It comes in a variety of weights so you can pick something that feels best to you in terms of weight and carrying comfort. It’s also waterproof, giving you extra peace of mind.

Cross-Linked Polyethylene

This sort of foam is similar to standard polystyrene foam, but there are a few key distinctions. This foam comes in a wider range of colors, which is fantastic if you want to paint your character’s sword a specific color. It also has a smoother texture than normal polystyrene foam and feels somewhat smoother in touch as well. If you’re searching for more weight in your costume, this type of foam can help. It’s also excellent at absorbing shocks; therefore, it’s great for pretend swordplay when wearing costumes.

Gym Rubber

This gray blade of metal is quite durable, even though it appears to be made out of plastic. It has a solid feel about it that makes it ideal for cosplay. It’s simple to cut and provides a smooth touch while also increasing durability. Any sort of foam intended for floor padding would do the job effectively because it delivers a good balance of light weight with strength for the finest of both worlds.

How to Make A Cosplay Sword

You will need a few supplies to make the sword, as well as basic techniques for completing the project. You will almost certainly require not only your selected foam type, but also other materials such as a sandpaper to smooth down the foam to your preferences, tracing paper, a sharp knife or box cutter that can cut through your chosen foam, a pipe of conduit to serve as the base and handle, a ruler to guarantee accurate measurements, and paint in various metallic hues for the appearance of metal as well as your chosen paint color for the handle or decoration on the grip.

After you’ve obtained all of the required materials, you’ll begin by tracing on the tracing paper the sword you want to make. Most cosplayers play characters with unique swords, so there’s no need to design your own unless you want to. You may also be able to download a template of the character’s sword, making it simpler. Whether you make your own outline or use a template, you’ll need to draw the sword on the foam with a marker. Ensure that you measure how long the sword will be before beginning so that it is precisely the length required. You must outline two distinct swords since they will be joined together to form a genuine sword’s proportions rather than a flat item’s dimensions.

The foam is then trimmed to suit the markings drawn from the tracing paper on it. You’ll need to make a first cut along the line, which is more about an accurate tracing of the marker with the blade than actual trimming, and then a second round of cutting to separate the outline from the foam and provide you with most of the sword’s components. The blade consists of several pieces, as well as a few foam cutouts for the handle.

If you want to create a realistic impression on the sword pieces, do it before you put the actual components together into a completed sword. It’s tidier, and the hues of the blade won’t get transferred to the handle or vice versa. You may use metallic silver paints to provide your blade an authentic metal appearance, while the grip can be painted brown or whatever color is suitable for your character.

The finished blade can be put together and finalized after the foam cutouts have fully cured. You’ll want to align the foam cutouts carefully and ensure that all of your measurements are correct while drawing lines on the pipe where the blade begins and ends, as well as marking where you will apply or soak in glue solution. This will not only help you line up your pieces correctly, but it will also serve as a sign for where to position the adhesive or glue solution.

Once you’ve determined the dimensions and markings, you may connect the pieces together with your adhesives. You may either use glue in the designated areas or a foam adhesive that you spray on to the foam to attach it to the pipe. After gluing on your blade and handle cutouts, allow it to rest for a few hours so that the glue fully dries. With this three-dimensional sword, you’ll be ready for your next cosplay event!

How to Make Prop Swords out of Flexible Foam

Here’s how to make a Mold Max 30 silicone mold with a FlexFoam-iT! 25 stunt prop sword. The outer skin of the FlexFoam-iT! 25 becomes tough, making it perfect for the end product. Cast Magic powders from Smooth-On are a quick and easy method to add color and depth to any casting. The finished prop is lightweight, flexible, and safe to use.


  • Mold Max 30
  • Cast Magic Silver Bullet
  • FlexFoam-iT 25
  • So-Strong Black
  • Mixing Sticks
  • Mixing Containers
  • Melamine Boards
  • Wooden Dowel
  • Adjustable Mold Straps
  • Gram Scale

Step 1: Prepare Mold

Begin by dusting Cast Magic Silver Bullet powder onto the mold surface and carefully closing it. After that, tie down the mold with adjustable straps and turn it on its side so that the pour spout is facing up. To provide your finished work additional sturdyness, insert a wooden dowel into the mold.

Step 2: Measure Foam

Fill a plastic or glass container with your desired measurement. Part A should be measured first, then place it in the oven at 350°F for 30 minutes. After removing from the oven, take care not to leave it exposed on top of an open flame because it might catch fire very quickly if you do so (Ensure that any heat source is completely turned off). If there are a few particles left unmelted, add another 30 minutes and keep up the temperature at 350°F for 1 hour before carefully removing from the oven. Fill a larger dish halfway full with crushed ice instead of using all of your allotted ice cubes.) Remove Part B from the oven when the liquid has fully hardened and cooled down, about 10-15 minutes later (

Step 3: Pour Foam

Combine parts A and B of FlexFoam-iT! Combine completely, being careful to scrape the container’s walls and bottom. As soon as mixing is completed, fill the mold with material.

Step 4: Demold

When the sword is completely cured, remove it. As the foaming cures, the Cast Magic powders adhere to it. The finished product is lightweight, long-lasting, and safe!


There are actually two types of swords to consider when constructing one: weight and durability. The weight of a sword increases if you concentrate on producing a sturdy blade. If you focus on making a light weapon, however, the durability is more often than not reduced.

This is why there are almost always heavier or more durable swords. The majority of people use sturdy blades as every-day weapons, while ultralight swords should only be used in competitions or on very special occasions.
