Thanks guys - these were two very good pieces. Would still love to hear folks opinion on their favorite steel for custom slip joint that will be used - (no saltwater) - want strength and edge holding - doesnt everybody

.
EDC usage for me may include cutting or trimming plastic, cutting cloth, cutting cardboard, maybe cutting poly-twine. I don't cut wire or drywall with it, but I might torque it a bit in cutting or trimming plastic. That's how I would use such a knife.
For a knife that was going to spend considerable time in my sweaty pocket, and would be called upon to perform the types of cutting that I personally do, I would want to factor in some corrosion resistance and some toughness in addition to edge retension.
For those properties I'm partial to 154CM / ATS-34, VG10, AUS10, or 440C. Those are listed in possibly decreasing order, but if any one of them were available, it would do. I have tried all of them in various blades and all of them have provided acceptable results for my EDC usage in my sweaty pockets. I had to buy them in lockbacks because they are not commonly available in slipjoints, but since you are going to have a custom made, that wouldn't be an issue for you.
Those are my preferences, YMMV.
