hello i want to buy a knife and a stone for my best friend, he is a professional chef like me. I have a Misono UX10 and a carbonext and he likes a lot. My idea is to buy a VG10 and a stone 1000/4000. I had thought of a Gyuto 210 mm, but has a global oriental knife, so I think that a Japanese slicer 240 mm perhaps it would be better. My budget is 150 Euros, about $ 200. If I spend a little less is better )) any advice?
