Has anyone had enough first hand experience with this material and can comment on its lateral strength during wood working and impacts?

I had a fellow forumite ask about me sourcing a piece of ATS-34 /ZDP 189 laminate from a guy here. I became interested mysef and am thinking of having a 4mm thick Scadi knife made from it with a bevel height of 7.5 mm. Does anyone know first hand of issues with ZDP strength for torsion or lateral loads?
 
In a laminate what you see regarding toughness/strength will be dominated by the side laminate. Durability won't be your main concern in that configuration, it will be using that steel designed for the exact opposite set of properties you want in a wood working knife, use one of the Sandvik steels. ZDP-189 in that style of knife is like M2 in an axe or L6 in a salt water fishing knife.

Thanks Cliff, you know how it is, you see stuff and hear about its great stregth dispite its C% and it got me to wondering. Given a choice of A2 or 01, what would you go with? (I am leaning towards A2)
 
ATS-34/ZDP 189 on a Scandi grind, boy is that a dream to sharpen. Would you like diamond dust bonded to your bevel as well? ;)

The whole point is that I was hoping not to have to touch it much (a blank 4mmX35mmX300 is about $60, hardly bank breaking stuff)

Thanks Cliff.
 
In the high carbide steels, at low angles, especially with no micro-beveling, you tend to get problems with edge chipping as this is how they blunt, damage is typically 0.1-0.2 mm deep for light work. Removing this damage by honing the entire bevel takes a *long* time on a low grindability steel.

I have been doing a lot of trials recently on S30V blades with bevels only about half as wide as typical scandinavian grinds, they have lower angles but the primary cuts them back, and it takes a *long* time to remove the chips and completely reset the bevel. You are looking at hundreds of passes on a really coarse stone.

I had considered 3V but its so expensive for makers to buy. I guess good old A2 will fit the bill.

On another note is the Sandvik steel available for makers to buy in small quantities?

Cliff, how would L6 perform with this grind if corrosion resistance was not an issue?
 
Devin Thomas sells AEB-L to knifemakers in ideal stock for scandinavian grinds, plus he has a damascus blend if you want aesthetics. Alvin Johnston has been working with L6, he grinds *way* thinner and is really positive. Any of the fine grained steels like 1095, 52100, etc. work well for that style of knife.
