The main difference between stamped knives and forged knives is their manufacturing process. They come through two different processes. The manufacturing procedure influences the hardness, heaviness, sharpness, edge retention, usability, and, ultimately, the knife’s price.
The typical process serial is: shaping; grinding; heat treating; and sharpening. Both knives follow this common process, but using tools and ways is different. The process is as follows:
- Hot Steel and Stamping process – For stamped knife
- Forging procedure and periods- For forged knife
What is a Forged knife?
A forged knife is made of a steel bar, which gets shaped through a high-heat grinding and shaping process. Sometimes it is made by machine, sometimes by craftsman. When the machine is the media/tool to make this knife, it is called Commercial Forging Technique.
On the contrary, when a craftsman makes it with a hammer and his hand techniques, the process calls the hand forging technique. So let’s see both processes in detail.
Whatever the process, to get precise cutting with less effort, forged knives are a brilliant option.
Hand Forging Technique
Craftsman makes these knives by hand techniques following the below steps:
Step 1: Shaping
When the temperature at the steel bar rises to 75% of its melting and shows a bright yellow color, it indicates the perfect time for hammering, molding, and shaping. Craftsman waits until that moment and then starts his job.
Step 2: Heat treating
Heat treatment is the most important step, which ensures the knife’s toughness, retention of sharpness, and grind ability. A strong and sturdy-edged knife is a result of rapidly heating and cooling the knife’s metal.
After coming through a heat-treating process, when the knife’s blade cools to room temperature following tempering, it improves the process and the product. The heat part may go for 2 hours at (347 to 662) degrees Fahrenheit, which cuts the knife’s brittleness and ensures a good balance in overall features.
Step 3: Grinding
When the knife gets its shape, grinding is the next step. You can grind the knife manually or with the machine using sandpaper grit. Thus, this process increases fineness after individual rounds. This part makes the blade’s edge sharp.
Next, attach the handle to the knife. If the design includes a bolster and a tang, you need to take finishing for these parts in this step.
Step 4: Sharpening
To gain the desired angle of the knife before sharpening, you need to let your knife through – cleaning, polishing, and inspecting.
Commercial Forging Technique
Expert knowledge, exclusive machines/tools, and a smart process – all create together forging knives in the commercial sector. Let’s see an in-depth look at the process.
1. Steel selection
Commercially manufacturers meticulously select premium grade steel with optimal composition with expert metallurgists’ guidance. They consider crucial factors, such as carbon content, alloying elements, and heat treatability, to achieve the desired blade characteristics.
Professional blacksmiths warm the steel to a specified temperature before shaping and refining the blade with traditional hammering techniques. This process aligns the steel’s grain structure, enhancing its strength and reducing impurities.
3. Heat Treatment
The forged blades undergo a precise heat treatment process involving quenching and tempering. Quenching cools the blade to increase its hardness, while tempering balances the hardness with resilience, reducing brittleness and enhancing toughness.
4. Precision Grinding
Highly skilled craftsmen utilize advanced grinding machinery to carefully shape the blade’s geometry, bevels, and cutting edge. This step demands meticulous precision to achieve optimal sharpness and cutting performance.
5. Handle Crafting
Experienced artisans meticulously craft ergonomic handles using wood, composite materials, or synthetic polymers. Considerations such as grip comfort, balance, and overall aesthetics are paramount in creating a handle that complements the blade.
6. Quality Control
Each blade undergoes rigorous quality control inspections to meet our exacting standards. It includes checking for blade straightness, hardness, edge sharpness, and overall finish.
