Induction Interface Disks
Because induction cookers use electromagnetic energy to generate heat, they work only with cookware made of iron or magnetic gauges of steel. (If a magnet sticks to its base, your pan will work on an induction stove.) For nonmagnetic cookware, the answer might be an induction interface disk, a Ping-Pong paddle–shaped device that sits under your incompatible pot and acts as a converter, transferring heat by conduction. We tested three models priced from $48.95 to $99.95, using them to boil water and make pancakes under non-induction-ready pans. One small carbon steel disk never managed to bring the 2 quarts of water to a boil or fully cook a pancake, and its metal feet scratched our cooktop’s glossy surface. We had more success with the other two models, made of smooth 18/10 stainless steel. These models reliably boiled water and cooked pancakes—albeit in twice the time it would take using straight induction and a compatible pan (or about the same time it would take on a gas burner). We strongly favored the Max Burton Induction Interface Disk, which has an aluminum core for speedy heat distribution and a comfortable, heatproof rubber handle. At $48.95, it costs less than a new induction-ready saucepan.

Victorinox (formerly Victorinox Forschner) 6-inch Straight Boning Knife: FlexibleThe nonslip grip and narrow, straight blade let testers remove the smallest bones with precision and complete comfort. Perfectly balanced with enough flexibility to maneuver around tight joints. The low price was a bonus. |

Wüsthof Classic Boning KnifeHefty in weight, this knife was a solid performer when removing poultry bones, and the handle was easy to grip, even when covered in chicken fat. Piercing silver skin was a challenge since the tip wasn’t sharp enough and the long narrow blade produced slightly jagged cuts. |

Mundial Boning Knife: FlexibleThe sharp tip performed well when removing silver skin, but it was too flexible when maneuvering around poultry joints, leaving testers feeling a lack of control. The heavy handle was slightly unbalanced and became slippery once covered in poultry fat. |

Shun Gokujo Filet KnifeDesigned to replicate a samurai blade, this expensive knife was a disappointment. It struggled to pierce the silver skin, although long cuts were smooth and even. Minimal flexibility and extreme curve got in the way when maneuvering around joints. The smooth handle was hard to grip and slippery. |

MAC Boning Knife—Chef SeriesThe large, cumbersome handle reminded testers of an outdoors knife for fishing and hunting. The blade was too wide to maneuver around joints and it struggled to pierce silver skin. Unlike other knives, this boning knife could only slice in one direction, making intricate cuts around joints difficult. |
★ | ★★ | $34.95 |

Messermeister San Moritz Elite Flexible Boning KnifeThe blade was so flexible it led to erratic cuttings; testers said the knife was hard to control. The blade was not sturdy enough to maneuver around joints and the lightweight handle felt flimsy and unbalanced. |
