Blade Strength
Safety comes first
Measuring Blade "Strength"
Our goal is to standardize the measurement and certification of all our flexible blades using a consistent, precise method. Our fully automated measuring device operates without human interaction, ensuring accurate and repeatable results. The machine tests blade flexibility by pressing down on feders and trainers, measuring the generated spring force. This method can also be performed at home, though with reduced accuracy.
To guarantee the highest quality, we test each blade multiple times throughout production and again before packaging, ensuring optimal performance in every piece.
Feders
Our feder blades are divided into three categories based on the force they generate when pressed 10 cm. This classification helps fencers select a blade that best matches their needs and training style, ensuring optimal performance and safety.
Characteristics:
- Extreme agility & flexibility
- Limited durability
- Lightweight
Recommended for:
- Light & controlled sparring
- Bloßfechten
Characteristics:
- Jack of all trades
- Flexibility & durability
- Pleasant weight distribution
Recommended for:
- Everyday use
- Casual & competitive fencing
Characteristics:
- High durability & life cycle
- Strong center line & “bind” hold
- Generally heavier design
Recommended for:
- Competitive fencing
- Heavy sparring
Check Feder Strength Requirements: Before selecting a blade strength, verify the feder strength regulations for your specific training or competition to avoid any issues.
Match Blade Strength & Hardness: To maximize lifespan, always use blades of the same strength and hardness against each other. Mixing different types can cause damage and void the warranty.
Natural Wear & Care: Blades naturally wear and develop burrs over time due to the properties of steel. While no blade lasts forever, proper care and maintenance can help extend their lifespan for years.
Swords
Most of our swords come in blunt or sharp variants, both designed with stiffness to replicate historical blades. Blunt blades excel in light sparring and drills, ensuring durability and safety, while sharp blades are ideal for cutting practice, refining edge alignment and technique. Each serves a distinct role in HEMA training, offering an authentic experience.
Historically faithful, has minimal flexibility. Due to the manual grinding process, each blade is slightly different, so it cannot be defined well by measurement.

Natural Wear & Maintenance: Blades naturally wear and develop burrs over time due to the properties of steel. While no blade lasts forever, proper care and maintenance can extend their lifespan for decades.
Edge Alignment Matters: Improper edge alignment can cause damage and void the warranty, affecting both sharp and blunt blades.
Avoid Hard Collisions: Blades can be damaged if they collide with hard surfaces or materials. Such damage is considered improper use and is not covered under warranty. Learn more about our warranty here: [Link]
Sharp Blade Regulations: Before ordering a sharp blade, check your country’s regulations, as laws vary regarding the possession and use of sharp blades.
Trainers
Our trainers are crafted to replicate the characteristics of historical weapons as accurately as possible while ensuring enhanced durability. Designed for resilience, their blades are well-suited for free fencing and tournaments. We continuously expand our selection to offer fencers even more high-quality options.

Measuring at Home
This is a quick, simple, and fairly accurate way to determine blade strength. Whether at home or in a competition, all you need is a personal scale.
- Position the Blade: Place the feder / trainer vertically on the scale and stabilize it by hand without applying force — just let it rest naturally.
- Zero the Scale: While the feder / trainer is still on the scale, reset it to zero. This step is crucial for accurate measurement.
- Apply Pressure: Press down vertically from the top until the blade reaches its resistance point—typically around 10 cm of deflection. This is the moment when the blade stops resisting and bends smoothly like a spring.
- Read the Force Value: Once in the no-resistance zone, note the measurement on the scale. This value represents the blade’s maximum spring force, also referred to as the Force of the Blade (FoB).
This method offers a cost-effective, yet consistent and repeatable way to measure blade strength, helping you gain a clearer understanding of how different blades perform.
Common Errors
By avoiding these common mistakes, you can ensure a more accurate and reliable measurement.
- Incorrect surface placement: Ensure the scale is placed on a flat, hard surface to function correctly.
- Not starting from zero: Ensure the scale is reset to zero with the feder/trainer still on the scale. This step is crucial for an accurate measurement.
- Incorrect angle: The feder/trainer should be pressed vertically, not at an angle.
- Incorrect pressure: Either not pressing down enough or pressing too hard can affect the result. The ideal deflection is between 10-12 cm.
- Scale calibration: There are many types of scales, and calibration may vary. However, in most cases, the results should still fall within an acceptable margin of error.
Important: use some hard surface material or a piece of rubber to dissipate the puncture force of the feder / trainer’s ’s tip to avoid damaging your scale.
