I like carbon on Trad knives for non food use and stainless for food.
On a pocket-knife, I really cannot understand the hoo-har about 'super' or 'better' steels. Better for what exactly?? I wonder what kind of day in day out tasks people who want the 'super' or newer steels are planning on subjecting their knives to?? A working pocket-knife should be easy enough to resharpen without complex or elaborate devices, otherwise the whole point of having a pocket knife for carry, is lost. Newer harder steels will be more complex to manufacture, much more problematic to resharpen and a lot more expensive. Knives cost enough already, thanks.
D2 is really nice on a pocket-knife ( I'm a major fan) but it certainly needs to arrive sharp and well presented otherwise fixing the edges is going to be a lot of time consuming, frustrating work for most people. Again, a bit self defeating. Contrary to what a lot of people say, it is not really so stainless, food work will soon turn it greyish or give spots to the blade an this can be a draw, it also imparts no flavour on foods.
