ClmtzJust going to copy paste my reply to Pawz2142.
Steel is only one part of a knife's production cost, with some others being handle material, handle complexity (e.g. interior milling, inlays, lock type, construction, lock inserts,) bearing type, blade and handle surface finish, tolerances, QC, etc. Paying for just the steel instead of looking at the overall knife can lead to poor purchases.
Also, S35VN is a fine steel. Chris Reeves uses it for a reason.
willgreenzillaSpyderco makes a production Dragonfly 2, Endura, Ladybug 3, Manbug, Stretch, and Delica 4 (among some others) in ZDP-189 and green FRN scales. ZDP is on the more difficult side of steels to sharpen, so if you're used to softer steels like 440 series equivalents, VG-10, or lower hardness carbon steels e.g. 5160 or 10xx spring steels, it might take some getting used to.
Some people report no difficulties with ZDP though, which I can only guess is due to them being very skilled and patient. Other than that possible issue it's considered a good steel somewhere between the likes of S30V/35VN and more recent high-end stainless steels like S110V and M390(/CPM 20CV/CTS 204P, all three of which are essentially identical). Though it's also reported to be unique in it's properties from those groups.
