I am sure this has been covered before and I did a search but did not get the answer. I have an idea what INFI is from reading the Busse web site and I know what SR101 is from reading the SRKW web site, but what is/was modified INFI? How does it compare to INFI? Is it hardened/tempered the way INFI is or is it differentially heat treated. I imagine it is not as good a steel as INFI but in what way is it a lesser steel?
