1. A stabilizer for use in a wellbore, comprising:
a downhole tubular configured to couple to a downhole conveyance in the wellbore; and
a plurality of helical blades extending radially outward from the downhole tubular, wherein the plurality of helical blades form a plurality of flow paths between adjacent blades, and wherein each blade of the plurality of helical blades comprises:
a line-of-sight face formed adjacent to a leading inner blade wall of the blade at a lower end of the blade,
wherein the line-of-sight face is parallel to a longitudinal axis of the downhole tubular, and
wherein the line-of-sight face intersects an outer surface of the downhole tubular at a non-orthogonal angle.
