Yes, T10 steel is generally considered to be a good steel for various applications, including knife making and tool production. T10 is a high-carbon steel that belongs to the category of tool steels. It is known for its excellent toughness, hardness, and ability to hold a sharp edge.

Here are some key characteristics of T10 steel:

1. Toughness: T10 steel has good toughness, allowing it to withstand impacts and resist chipping or breaking. This makes it suitable for applications that require durability and the ability to handle heavy-duty tasks.
2. Hardness: T10 steel can be heat treated to achieve high levels of hardness, typically falling within the range of 58-62 HRC (Rockwell hardness scale). This hardness contributes to its ability to hold a sharp edge for a prolonged period.
3. Edge Retention: Due to its high carbon content, T10 steel can hold a sharp edge well, making it suitable for applications that require excellent cutting performance.
4. Wear Resistance: T10 steel exhibits good wear resistance, allowing it to withstand repeated use and maintain its performance over time.
5. Heat Treatability: T10 steel is known for its ease of heat treatment, which enables bladesmiths to achieve the desired hardness, toughness, and other properties through proper quenching and tempering processes.

It's important to note that the quality of T10 steel can vary depending on the specific composition and manufacturing processes. The skill and expertise of the bladesmith or manufacturer also play a significant role in determining the overall quality and performance of the final product.

When considering a knife or tool made from T10 steel, it's advisable to source it from reputable manufacturers or bladesmiths who have expertise in working with T10 steel and adhere to quality standards in their production processes.
