A well bowled off cutter is the equivalent of facing a fast off spinner.
It moves the ball off the pitch from the off-side of a batsman towards the leg-side.
The hard work's done in the fingers because they cause the ball to rotate on release.
This also means the ball is released at a reduced pace so this is an excellent way of bowling a slower ball.
The ideal spot to land an off cutter would be on or outside a right-handed batsman's off stump.
The amount of movement off the pitch is determined by how straight the seam is, the pitch, the condition of the ball and of course, the bowler.
With the seam vertical, the index finger is placed along the seam with the middle finger about two centimetres away.
The thumb is underneath the ball, also on the seam, and the ball rests against the third finger.
As the ball is released, the index and middle finger work down the side of the ball so that the thumb passes over the top of the ball.
This generates all the spin on the ball.
