Customize Engine Weight: Metal Sharp
Flat surface with a small metal point in the centre.
Tip has some precession, however for use with Right Customize Gear (Free Shaft Version) it is outclassed by Light Sharp, which has excellent precession and allows for actual Zombie customizations (albeit right-spin only).
However, Metal Sharp ends up being more notable due to chemistry with Gyro Engine Gear, providing surprisingly excellent stability due to the low height, somewhat ball-shaped tip, and bevelled surrounds combined with the bearing support offered by the part reducing the impact opponents can have on its stability. As such, it ends up being arguably the best true CEW competitively.
