My recently purchased Small Inkosi Plain made in Feb 24, 2021 even tho came with a box and card saying CPM-S35VN, when I took the knife apart the blade tang reads "45". I had to take it apart since it ceased to open with the blade right up against the show face handle slap out of the box (everything is perfect now upon smoothing out the washers and careful reassembly / adjustment). Imagine my initial CRK impression lol!
I've also just bought a Small Sebenza 31 Plain with CPM-S45VN made on May 13, 2021, the fit and finish along with the blade deploy and closing action are fantastic out of the box. However this Small Sebenza 31 does have a tad of lock rock by simply holding the knife in the hand and apply thumb pressure to the spine near the tip, I can hear a faint click (the Small Inkosi is rock solid). Will see if the minor lock rock will go away with use as the ceramic ball wears a deeper groove into the tang.
