Trail Master. SK5 or 0-1?

[Aleous]

So I've decided to buy a CS Trail Master but can't decide if I should buy it in SK5 which is analogous to 1080 high carbon steel I've read or buy it in the new 0-1 tool steel which is $20-30 more expensive.

Anyone have experiences with both these steels or both these models? Is it worth the extra cash or should I just buy the SK5?

Thanks.
