Have any of you seen or tried the newly released TKeller series of knives made by the Chinese knife maker Cangshan? The blades are made from RWL34 produced by Damasteel of Sweden. The blades on the prototypes were etched as having been heat treated to HRC 65 (+/- 2). However, the blades of the production knives (currently exclusive to Williams Sonoma) are etched as being heat treated to HRC 61 (+/- 2). I'm not familiar with this steel, so if any of you are, do you think the HRC was lowered to reduce chipping or for ease of sharpening (or both)?
