I'm making a couple of thin kitchen slicers in S90V. For this application, what would be the recommended target hardness after heat treatment?
 
It’s been a bit since i’ve heat treated any but I think 60-61 should be good.

Thanks, Hoss. Will it be tough enough at 60-61 that I won't need to worry about the tips breaking off thin knives? These knives are expected to live normal, well cared for lives slicing roasts etc.
 
That’s always a worry but should be fine. I’ve never had any problems with it. It was developed for wear resistance more so than toughness however.

Do you have any thoughts about s90v vs s110v? In a kitchen setting would one have any advantage. I have only used it in folders and have been pretty "meh" about it. If I cut cardboard for a living it would be another story. With my wife's cutting habits I have wondered about using it in the kitchen though.
 
I’ve never tried S110V so I won’t be any help there.

I usually laminate my high wear resistant steels to softer stainless cladding for more toughness and easier finishing. I’ve tried 10v, k390, vanadis 10, and have some vandis 8 to try. I prefer the high wear resistant tool steels over the high wear resistant stainless steels.

Hoss I will be very interested in your results with the Vandals 8. I have a Bar of it and have found very little useful info on real world use.
 
For some reason high vanadium stainess also never appeals to me. I found it lose very sharp edge very early... actually I found almost none improvement in edge retention in reality from steel like s90v or s110v compare to something like XHP or S30V.
