The last I checked, 440-C is still a pretty good stainless steel, which is what most of Jantz's kits include. I know 440-C is not as primo as some of the fancier steels that has come about in the past several years, but it is still a very good functioning steel.
Most of the blades I make are from ATS34 and 440-C. The ATS34 is a higher quality steel with better edge holding, but I don't notice that much difference between them when it comes to cleaning animals. 440 needs to be sharpened a little more often, but other than that, not much difference to me.
I don't think you would go wrong with one of their 440-C kits.
But back to your question, I have not seen kits available in high carbon.
I would imagine anything you make and give as a gift, will be much appreciated. I have sold a few but have given many more away to friends and family, and never one complaint.
Have fun, it's addictive!
