Magnacut is given the same rating as D2, 3V, VG10, and "440" (presumabbly 440C). Elmax, M2, and Cruwear are rated higher.

CATRA testing by Magnacut's creator[0] suggests D2, 3V, VG10, and 440C should have a lower rating than Magnacut for edge retention, while Elmax, M2, and Cruwear should be the same. 5 probably is a reasonable rating for Magnacut though when Maxamet is 10.

Exotic outliers like Maxamet or 10V skew things so much they should be left off of ranking scales.

Larrin's ratings handle this by not having a fixed scale; REX 121 gets a 12 for edge retention. The rating seems to be roughly CATRA cards cut divided by 100.
