Why create a knife blade with 420J steel on the outside and ZDP189 on the inside (well - the cutting edge is ZDP189)? Why not just use ZDP189? Also - is ZDP-189 more prone to chipping? I ask since I really like the Spyderco Caly 3 but am leery of the blade steel.
Any thoughts?
[EDIT] Also read that 420J scratches easily.

Benefit of ZDP189/420J Laminate?
