Diagonal cutter

These long-handled, short-jaw cutters allow you to get into close quarters and clip twisted safety wire. Diagonals or dikes are available in extremely small sizes for delicate electronic and instrument work as well as large sizes up to about nine inches in length.
A special form of cutter, quite similar to diagonals is the flush cutter. These cutters leave a perfectly smooth edge on the part they cut and are often used for cutting the stem off friction-lock rivets or for cutting electrical wire flush with its solder joint. See figure 1 for example.
