Create technology icon set with a style inspired by early 20th-century woodcuts and stone carvings, merged with clean, modern vector lines. The icons should be solid and robust, formed from geometric shapes that convey strength and simplicity. Use solid shading lines to add depth and texture, ensuring consistency in shading size across the entire set. The shading should have a 2X size consistency, even when additional gridlines are added for larger icons. Icons should be designed within a 41x41 grid, with subtle curves incorporated to soften areas where straight lines may feel too harsh. The overall aesthetic should be bold yet refined, with each icon feeling like a cohesive part of the same family. These icons will be used for both digital applications and marketing materials, so they should be versatile, impactful, and visually harmonious.
