Sharpening stones that do well with s30v and 5160

Thu Apr 18, 2013 5:56 pm

Hello

I'm interested in purchasing some water stones but most my knives are s30v and 5160 carbon steel etc....

I'm looking for stones with a longer life span but can also sharpen other steels be it kitchen knives etc...most my personal knives are for hunting and survival type situations but I tend to sharpen friends and family's every day type knives which are usually low quality steel.

What would you recommend as this is my first venture into water stones

Thanks
Tyler

Try this set. It's good, all inclusive and will work on any number of knives: http://www.chefknivestogo.com/knshcoset.html

5160 also used as the steel for leaf springs on trucks its a very tough carbon alloy steel though should sharpen like most other carbon steels.

S30V on the other hand is a stainless high wear resistance powder metal that in truth does poorly when sharpened on waterstones. Even the best of waterstones have troubles especially beyond 1k. Because of the nature of this steel its also not to your benefit to finish to a fine grit, around 300-600 mesh diamond abrasive or a fine silicon carbide stone and a bit of stropping is the sweet spot for S30V.

Interesting info. Thank you.

i wonder how s35vn does since they're closely related

Depends on the heat treatment but from my experience its harder to grind than S30V.

Shaun don't you forge your knives out of s35vn? Any input?

I'd like to hear your thoughts on this too Shaun.

Two very different steels. 5160 will respond well to waterstones. For S30v, diamonds and CBN are your friends. On the low end Atoma plates up to 1200 grit (140 400 600 1200) are ideal and switching to compounds after that. 4 micron CBN then 2 then 1 micron. I haven't had much luck going to real acute angles with S30v. I find S35vn (Niobium carbides) a much nicer steel to work with.

+1 @ Ken

Just finished a customer S30V ZT-0350 to a mirror.

....and I have to agree that the Shapton GS stones suck with S30V!
