Are you saying that spheroid weathering cannot produce sharp edges? Usually sharp edges are produced by mechanical weathering mechanism (like exfoliation and frost wedging, and dependent on the climate in this region frost wedging could certainly play a role in the weakening of the separations rock produced by spheriodal weathering) but you will notice by the definition below spheriodal weathering is stated to be similar to exfoliation produced usually by mechanical weathering.

By what weathering mechanism...

I will reiterate the definition of spheriodal weathering:

spheroidal weathering A form of chemical weathering in which concentric shells of decayed rock (ranging in diameter from 2 cm to 2 m) are successively loosened and separated from a block of rock by water penetrating the bounding joints or other fractures and attacking the block from all sides. It is similar to the larger-scale exfoliation produced usually by mechanical weathering. Syn: onionskin weathering; concentric weathering; spherical weathering.

Do you have another weathering mechanism that produces concentric separations of the host rock bounded by joint planes?

That is right the main mechanism of erosion is runoff which is eroding the weathered rock... remember weathering involves little to no transport of the debris.
