Narrative:

After landing on rollout; slowing through 70 KTS; severe shimmy observed. Captain released brakes and shimmy continued until aircraft almost stopped. Pulled off runway; had crash fire rescue equipment trucks check aircraft over for possible tire failure. Everything normal outside and inside aircraft (brake temperature about 100 degrees). Taxied to gate. Maintenance at gate found nose slash deflector rubbing against right nose tire. This seems to be happening more often. Not sure if this is a trend.
