Source: steel sliding against a lined scabbard and its metal throat; two independent noise bands model coarse rubbing at 450-2200 Hz and fine asperity friction rising from 1400 to 6400 Hz.
Body: the blade has inharmonic bending modes at 920, 1570, 2690, 4310 and 6180 Hz, scaled by size. Paired modes differ by 2-6 Hz; upper modes decay faster, with T60 values of 0.24-0.62 s.
Envelope: contact begins over 8 ms, accelerates for 0.4 s, then clears the throat over 35 ms. A 12 ms release excitation frees the blade's bright ring; the default ends in about 1.2 s.
Movement: rising friction bands model accelerating contact, while the blade modes stay fixed; irregular 37 Hz rubbing modulates the scrape gently without producing separate impact clicks.
Variation: seeded mode tuning varies by 0.6 percent and contact texture wanders independently. Draw time, blade size, lining brightness and ring damping distinguish quick, heavy, lined and bright draws.
Space: dry, centered and mono-compatible; no room tail or low-frequency cinematic impact is added.
