you should list a price (unless it is free)

A thing to note about the Toor Karsumba is that (I believe) it's CPM-154, a finer grained powdered steel form of 154CM...and very well made Toor offering.

Yeah, as far as I understood it the 154CM and the CPM154 were almost compositionally exact, but the CPM was the new kid on the block and had some minor “upgrades,” but I am definitely not a metallurgist, so you are probably right. |

It should be more or less similar to the question of 1095 vs T10 steels. T10 "should" be the Chinese variant of 1095 and a bit "better" with additional manganese or tungsten (as far as I remember), but in all practical matters both steels seem to look and perform the same.

The CPM process produces finer grain structure and better mixing of ingredients making for a tougher, more wear resistant version of the steel. AFIAK 154 is a steel that does not profit much from being CPM though (154CM already has a pretty fine microstructure). CPM-D2 has a much bigger advantage over D2 for example.

You mean like when people compare what’s better, 5160 to 9260? That drives me as crazy as the whole 9mm vs .45 fiasco. They are both spring steel, and I have swords/knives made of both so I’m not being biased here, and each obviously have their own compositions, but to each his own! |

Wow, maybe you are the metallurgist here! lol I know that Benchmade, Microtech, and Spyderco, all heat treat the same metals (D2, s30v….etc) differently, with somewhat altered results between them. |
