The triangle grapefruit knife is the perfect tool for filleting citrus fruit pieces such as grapefruit, oranges or lemons. To produce grapefruit fillets, first cut the grapefruit into two halves. Take one half and insert the angled tip outside of the fillet. Both sides of the thin blade are serrated and sharpened for easy cutting of the sensitive fruit pulp to avoid splashing. In addition, the thin blade allows for flexible movements when cutting the fruit. Citrus fruits fillets are a healthy snack for young children as they don’t need to chew on any remaining fruit skin. Also, we love to eat grapefruit fillets in salads.
