Yes, 9260 spring steel is considered to be a good material for swords, particularly functional and durable blades. Here are some reasons why 9260 spring steel is favored by sword enthusiasts and swordsmiths:

1. Toughness: 9260 spring steel is known for its high level of toughness, which allows it to withstand impacts and resist deformation without fracturing. This toughness makes it suitable for swords that may encounter rigorous use, such as cutting practice and martial arts training.
2. Flexibility: The high-silicon content in 9260 steel contributes to its flexibility. This flexibility enables the blade to absorb shock and return to its original shape, making it less prone to breakage. It allows for resilient cutting performance and enhances the overall durability of the sword.
3. Impact Resistance: The combination of toughness and flexibility in 9260 spring steel provides excellent resistance to impact forces. This makes swords made from 9260 steel capable of absorbing shocks during cutting, slashing, and striking techniques without suffering damage or failure.
4. Edge Retention: While 9260 spring steel is not known for exceptional edge retention compared to some other steels, it is still considered suitable for functional swords. Proper heat treatment and blade geometry can influence the edge retention of a sword made from 9260 steel.
5. Cost-Effectiveness: 9260 spring steel is relatively affordable compared to some other high-performance steels used in sword making. It provides a good balance between performance and cost, making it an attractive option for functional swords within a reasonable budget.

It's important to note that the specific performance of a sword made from 9260 spring steel can vary depending on factors such as heat treatment, blade geometry, and overall craftsmanship. The skill and expertise of the swordsmith in forging, heat treating, and shaping the blade are crucial in bringing out the best characteristics of the steel.

When considering a sword made from 9260 spring steel, it is advisable to evaluate the reputation and expertise of the swordsmith or manufacturer, as well as factors such as the design, balance, and overall construction of the sword to ensure a high-quality and well-performing blade.
