Introduction

The Spyderco Para 3 and S9 TV is a highly anticipated folding knife that comes with carbon fiber handle scales. As an avid knife enthusiast, I couldn't wait to get my hands on it. After purchasing it from River's Edge Cutlery, I was eager to test its performance and see if it lived up to its reputation. In this article, I will share my experience with the Spyderco Para 3 in S9 TV and provide an in-depth review of its features, steel composition, performance, and sharpening process.

Features of the Spyderco Para 3 and S9 TV

The Spyderco Para 3 in S9 TV is a tool that is still made by Crucible. It features a stainless steel blade with extremely high wear resistance. The carbon composition of S9 TV includes 2.3% carbon, 14% chromium, 1% molybdenum, and 9% vanadium. These elements contribute to its excellent wear resistance and corrosion resistance. The knife is designed with a three-inch blade, making it compact and easy to carry.

Steel Composition: S9 TV

S9 TV is a stainless steel known for its exceptional wear resistance. With a high composition of vanadium, it forms vanadium carbides, leaving chromium free in the steel matrix for enhanced corrosion resistance. The chromium content of 14% ensures that the steel is considered stainless. Compared to 440C, S9 TV offers higher toughness while maintaining similar corrosion resistance. Some misconceptions about S9 TV being Chippy or brittle are unfounded, as this steel boasts higher impact toughness than 440C.

Performance Testing

To evaluate the performance of the Spyderco Para 3 in S9 TV, I subjected it to various cutting tests. I started with cardboard, where it effortlessly sliced through the material. Next, I moved on to zip ties, a common test for edge retention. Contrary to some opinions, the knife showed no signs of chipping or dulling. It then effortlessly cut through 5/8-inch Manila rope, showcasing its cutting ability on tougher materials. The knife excelled in cutting into softwoods like pine, demonstrating its excellent edge geometry and ergonomics. Even after extensive use, it could still cleanly cut paper, although a resharpening was required.

Sharpening S9 TV

Sharpening S9 TV can be challenging due to its high wear resistance. However, with the right technique and tools, achieving a razor-sharp edge is possible. I followed a specific routine that included using coarse and fine DMT plates, an extra-fine DMT plate, a Spyderco ultrafine ceramic stone, and leather stropping with diamond compound. The process ensured a sharp and aggressive edge, maintaining it for an extended period.

Comparison with Other Steels

S9 TV shares similarities with S110V, another steel known for its high wear resistance. Both steels can be challenging to sharpen, but with the right approach, they offer outstanding edge retention. However, they are not as tough as steels like 1095 or 3V. It's important to consider the trade-off between wear resistance and toughness when choosing a steel.

Conclusion

In conclusion, the Spyderco Para 3 in S9 TV is a well-executed folding knife. Its high wear resistance, corrosion resistance, and excellent edge retention make it a valuable tool for various cutting tasks. The ergonomics and overall build quality of the knife are exceptional. While not the easiest steel to sharpen, it rewards with a razor-sharp edge and long-lasting performance. The Spyderco Para 3 in S9 TV is a worthwhile investment for knife enthusiasts looking for a Durable and high-performing tool.
