In sabong, precision and performance are everything. Your gaff knife isn’t just a tool—it’s a decisive factor in every match. That’s why the type of steel you use matters more than ever.
In this blog, we’ll dive into the importance of steel selection, explain the properties that affect performance, and explore why modern steels like powder metallurgy (PM) steels are setting a new standard for gaff knife makers and serious breeders.
🔍 Why Steel Selection Is Critical
A gaff knife undergoes extreme stress during a fight—rapid strikes, piercing resistance, and unexpected impact. If the steel is too soft, it dulls fast. If it’s too hard and brittle, it could chip or break at the worst moment.
That’s why choosing the right steel is a balance of science and skill—and a decision you shouldn’t leave to chance.
🧪 Key Steel Properties You Need to Understand
Here are the four most important factors to consider when selecting steel for gaffs:
🔹 1. Hardness
Measured on the Rockwell (HRC) scale, this determines how well your edge holds up. Ideal gaff steels sit in the 60–65 HRC range. Too low = dull. Too high = brittle.
🔹 2. Toughness
Toughness means the steel can take a hit without cracking. In sabong, a blade needs to be tough enough to survive sudden impacts while maintaining integrity.
🔹 3. Wear Resistance
High wear resistance = longer edge retention. Steels like M2 HSS or PM steels outperform traditional types in this area, making them ideal for multi-round use or derbies.
🔹 4. Corrosion Resistance
Essential in humid conditions, or when storing your gaffs long-term. Stainless and certain PM steels resist rust better than older carbon steels.
🧰 Common Steels Used in Gaff Making
| Steel Type | Characteristics |
|---|---|
| Leaf Spring (5160) | Traditional, tough, but rust-prone |
| Hacksaw Blade (M2) | High-speed steel, great edge retention |
| Circular Saw (M35/M42) | Cobalt-based, heat-resistant, very hard |
| PM Steels (e.g., Apex Ultra) | Next-gen steel: clean, ultra-tough, ultra-sharp |
⚙️ Powder Metallurgy: The New Era of Gaff Steel
Powder metallurgy (PM) steel is made by atomizing molten steel into fine powder, then compacting and sintering it. This results in:
- Uniform grain structure
- High purity
- Superior edge strength and toughness
Premium PM steels like XCalibre Apex Ultra offer maximum sharpness, incredible toughness, and excellent wear resistance—making them perfect for competitive sabong blades.
🎯 Why Understanding Steel Gives You an Edge
If you’re a gaff maker or breeder, you need to know more than just how to shape or mount a blade—you need to understand the material itself.
A better understanding of steel allows you to:
✅ Optimize heat treatment
✅ Choose the best steel for sparring vs. derbies
✅ Avoid breakage, chipping, or failure
✅ Maintain consistent blade performance every time
🏁 Final Words: Make Every Strike Count
Steel is the heart of every gaff. No matter how good your design, if your steel fails, the match is over. As metallurgy evolves, so should our choices.
If you’re serious about your craft, know your steel. Choose better. Strike harder.
