Usually shear is a weak verb. Shorn and shore are not commonly used: indeed, shore is rare, even in poetry.

This heard Geraint, and grasping at his sword,
Shore thro' the swarthy neck.
—Tennyson.

Shorn is used sometimes as a participial adjective, as "a shorn lamb," but not much as a participle. We usually say, "The sheep were sheared" instead of "The sheep were shorn."

Went is borrowed as the past tense of go from the old verb wend, which is seldom used except in poetry; for example,—

If, maiden, thou would'st wend with me
To leave both tower and town.
—Scott.
