Thinking to buy Stretch 2 and Delica 4 as my two knofes used for camping, trekking and all activities i do outside including cutting food.
I wonder which steel you recommend for Stretch2?
I am a person who do not have a knowledge about sharpening
With what you said, I would go with the Vg-10 for blade steel. It is just a great user steel. This and a Sharpmaker will serve you quite well.
Not hating on ZDP at all, in any way. I even had my Dragonfly go through the washer machine and come out, well, clean. Years later, no sign of rust, and the edge retention really is incredible.
However, VG-10 is a great place to start, in my opinion. Enjoy what you purchase!
