A form of graffiti in which markings are etched into hard surfaces. Particularly prevalent in NYC Subways where Graffiti remover and a "Clean Train" policy have all but eradicated traditional aerosol graffiti.

Considered by many a low form of graffiti as the difficult etching leaves little room for artistic design, scratchiti is often simply block-lettered tags used to promote a particular urban artist or claim territory, or amature copycat work.

Tools employed in the craft are generally keys, knives, and razorblades, but Lava Rocks available at hardware stores, Carbide tipped drill bits, and spark plugs have been reported as tools of choice as well.

Occasionally, detailed etching work is spotted, and is assumed to be done using an apparatus similar to a Dremel Tool.
Many straphangers consider Scratchiti to be a blight on their subway.
