Traditional mould made fine art papers are torn from the mill, while wet, resulting in a rough, softly ripped look that is favoured by many artists. Achieving this look with inkjet prints is difficult, however it can be done. What you need is the Dual Edge Ripper. This is a gruesome looking plastic ruler with irregular jags on it with which you tear the paper, resulting in a very impressive approximation of a true deckle.

If you want to get even closer to the true deckled edge look, you can do so by slightly wetting the edge of your paper (dip the edge for about one second in water or use a moist sponge, you will need about 2 inches spare space around your print - one inch for the border, one inch to rip. Don't let the water wick its way any closer than 1cm to the actual print! After the rip, press the print edge for some time between layers of absorbant paper).

The dual edge ripper comes in a 24" length. To tear anything longer than 24", just move the ripper along as you go.
