The sharpening stone is "tearing" small particles of metal from the edge of the blade, this produces heat which makes the particle glow almost white hot, the knife also gets hot but because there is more metal it dissipates (spreads out) more, the blade will go blue, and will be much to hot to touch for a short while.
