Blunt tungsten grind angles can distribute heat across a wider area, are less subject to spitting, and can endure more heat. They are considered by many to offer better penetration, but this is really due to their ability to withstand the heat needed to obtain greater penetration. Blunt tungsten grind angles have their own disadvantages as well.

Use a dedicated, tungsten-only grinder or sander. Grind parallel to the length of the rod, never across it. Hold the electrode to the grinder wheel at an angle of 22.5°. Taper back about 2/3 of the rod diameter and leave a flat spot about 2/3 of the rod diameter on the tip for the best arc. Wipe it clean with acetone.
