A cutting tool may include a holder and a cutting insert. The cutting insert may include a ridge including a corner and a first side. The holder may include a first flow path extending along a first central axis, and a second flow path extending along a second central axis. A line obtained by extending the first central axis may be a first imaginary line, and a line obtained by extending the second central axis may be a second imaginary line, each of the first imaginary line and the second imaginary line is inclined downward. An intersection of the first imaginary line and the second imaginary line is located outside of the cutting insert in a plan view. The first imaginary line intersects with the ridge and the second imaginary line intersects with the first side at a side closer to the second end than the first imaginary line.
