Toughness 5160 VS CPM 3V

[Neo]

This question is asked in another thread in another subforum
http://www.bladeforums.com/forums/showthread.php?t=723440

Trying to bring this under a bigger exposure I'll post this in the general knife discussion.

Hypothetically, in what situation would you need a knife steel tougher than CPM 3V?

If a steel like A2 is not tough enough, you would want a big toughness upgrade like 5160 or S5, rather than moderate toughness upgrade like 3V.

How tough is 5160, tougher than 3V?

Can you give some joule/ HRC

S7
165 joule / 57 HRC

S5
193 joule / 58 HRC

S1
212 joule / 59 HRC

3V
113 joule / 58 HRC
95 joule / 60 HRC
53 joule / 62 HRC

A2
45 joule / 58 HRC
50 joule / 59 HRC
56 joule / 60 HRC

5160
?

Thank you

5160 is pretty tuff with decent edge holding...

CPM 3v is magic

IIRC it is ALMOST as tuff as S7 with better edge holding

5160 isnt even in the same universe as 3V. 3V definitely better than 5160
