Here is my latest 4"-5" utility knife. It's an online-only, not sold in stores. It feels very good in the hand.
4 3/4" 9CR18MOV blade. Composition is similar to 440C but with Molybdenum and Vanadium added and finer carbides (the best grade of steel made in China). Fairly easy to sharpen, excellent corrosion resistance, good edge retention. Removable G10 handle scales.
