So beautiful wavy garnishes we can make with wavy knives. I have a few very nice in my kitchen but for curiosity tried to make from a can lid wave garnishing knife. It took me a few minutes make one. Every wave design on the photos I made with my handmade knife. The wavy handmade garnish knife from a can lid worked well for on a small amount vegetables.
You can shop online and buy nice one Wavy French Fry Cutter or make yourself.
