Resistance of Kanthal is pretty straightfoward... here's a comparison at 0.1mm diameter popular heating wires.

38 AWG Round Kanthal A1 Wire - 0.10mm diameter, 55.8Ω/ft, 183.1Ω/m

38 AWG Round Nichrome 80 Wire - 0.1mm diameter, 42.23Ω/ft, 138.52Ω/m

38 AWG Round 316L Wire - 0.10mm diameter, 28.5Ω/ft, 93.5Ω/m

just for comparison:

38 AWG Copper wire - 0.10mm diameter, 2.13Ω/m

of course he would be using a heavier GA wire... most likely 22 or 24 or better. But it's nice to see comparisons.
