I sometimes receive s question saying - I often work with acidic vegetables such as tomatoes. Any special recommendation in choosing a knife?
For strong acidic vegetables, Japanese traditional high carbon steel gets rusty quite easily. I recommend knives made by semi stainless steel. Popular semi stainless are VG10, R2/SG2, Silver Steel No.3, and Molybdenum. Knives with these material are easy to maintain, and also chefs who work with acidic foods would find that knives are resistant from getting rusty.
