The invention discloses a multifunctional shield with S-shaped guiding grooves. The multifunctional shield comprises a shield body, wherein the horizontal cross section of a shield body front surface comprises apices and two lateral points; the apices are combined into an apex intersecting line; the lateral points on each side are combined into a lateral point intersecting line; each apex and a corresponding lateral point are combined into a lateral edge; the height of the apex intersecting line is gradually reduced, and the apex intersecting line extends to each lateral point intersecting line to form a lateral side; the shield body front surface is axially symmetrical along the apex intersecting line axis; each lateral side comprises the guiding grooves and guiding ridges; each guiding groove comprises a groove head, a groove body and a groove tail; each groove head of the apex intersecting line transversely extends to the groove tail of the corresponding lateral point intersecting line to form the corresponding groove body; each groove body is formed in an S shape; each guiding ridge is arranged between two corresponding adjacent guiding grooves; and the S shape of each groove body comprises a complete S shape, or partial S shape, or a plurality of continuous S shapes. Through the adoption of the multifunctional shield, sliding distance and sliding resistance are effectively increased, impact force to a person holding the shield is relieved, and the sliding speed of an attacking object is reduced.
