Henry,
Have you posted your chipping problem on the Spyderco Forum(s)? I'm sure Sal and the others would like to know about this. This would greatly help improve the product and would add to the knowledge depository on S30V, which is relatively new. I'm sure any knife with a thin edge and acute angles would chip under hard use, but edge chipping on S30V on small folders is not common. I believe there were some problems with CPM440V used by Spyderco previously, although I found CPM440V on my Gunting to be absolutely wonderful - edgeholding and the ability to take a razor finish. Dont' know about toughness tho'.
