I may have misread the working edge being equal to S30V too many pages open on a phone
I made a big mistake.
CTS-BD1 is not what the new Para3 is using.
It is using CTS-BD1N
From ZK Knies App
C: 0.80-0.95; Cr: 15.00-17.00; Mo: 0.50;

CTS BD1N - CTS-BD1N is a high Carbon, high Chromium, Nitrogen martensitic stainless steel. Can be hardened in oil or air. CTS-BD1N was designed as an improvement or an evolution of the Carpenter CTS-BD1 stainless steel, which was also used in knives. Overall, CTS-BD1N has higher working hardness compared to CTS-BD1 steel, up to 63HRC. The most notable difference between CTS-BD1N and CTS-BD1 steel is the Nitrogen. To be more precise, or at least according to the official specifications, 0.10% Vanadium present in CTS-BD1 steel is gone from CTS-BD1N, and instead we have 0.10%-0.15% Nitrogen. While it may look about the same amount, in reality 0.10% Nitrogen will produce almost 4 times more atoms than Vanadium due to its smaller molar mass. Vanadium is a welcome addition to any steel, but to be honest I am not sure if it's completely gone from CTS-BD1N, because in other alloys 0.10% Vanadium is considered trace amount or unintentional. On top of that, CTS-BD1N has more Chromium, Manganese and Silicon in its composition. Anyhow, if CTS-BD1N contained or retained that Vanadium it'd not hurt for sure. Overall, CTS-BD1N is a very decent candidate for a knife blade, fine grained steel, with high corrosion resistance and respectable edge holding ability. At max hardness CTS-BD1N can sustain high polished, 12°-15° per side edge.
Make Mine Spyderco
I have tried many different High End brands and only Spyderco consistently produces High Quality Knives with the most Innovative Steels and Incredible Designs and often for less money than others.
I have been surprised many times by Sal's design in the dark philosophy and agree with it. How it feels in the hand and how it cuts matters more than how it looks. Lipstick on a pig, does not make it something other than a pig.
