This is a high carbon laminated steel blade: with a center layer of high-carbon steel hardeened to 58-60 Rockwell, surrounded on each side by a layer of lower-carbon steel to add blade strength. The size and profile of this knife would make a great all-around utility knife.
Here are the fittings that this blade can be paired with, based on the sizes of the blade, tang, and slot. Any fitting labelled "might be too small/big" will still fit the blade, but might not be a good match depending on the style of knife that you're making.
