text: A partially hollow blade (​1⁄ 2 or ​1⁄ 4 for example) cannot sustain the same degree of sharpness for as long, because as the cutting edge erodes it can eventually reach the stabilising ridge faster where there is more material and thus the cutting-edge bevel cannot be maintained without excessive honing of the stabilising ridge to remove the additional material, which could also destabilise the rest of the blade.
