It is referred to as CPM 154 cm in numerous places, including Steel Barons who are a retailer:

As for S30V, my problem with it was not that it chipped but that it rolled like there was no tomorrow: Chopping on a 3" diameter piece of Maple, with a 10.5" blade from a star maker costing around 2ks, 0.040" edge at around 17 degrees per side, I could pick a spot forward on the edge, chop once or twice, then pick a spot back on the edge, chop once on twice, and the two separate spots would produce nail shavings from my nails on one side only... That is micro-rolling with one or two chops on Maple...
That being said, I've seen badly done 440C that would roll on Maple so bad the edge would literally be pointing UPWARDS when the unrolled portions pointed down: This in a SINGLE stroke on Maple... And I've seen a Neeley 440C that chipped at over 20 degrees per side on wood, losing visible chunks off the apex at every stroke...
I've tested many, and that is why I say the best thing to see stamped on a blade is JAPAN, then Randall... Al Mar is always JAPAN anyway...
