Induction Interface Disks
How we tested
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.
The Results
Design Trifecta 360 Knife Block
Admittedly expensive, this handsome block certainly seemed to live up to its billing as “the last knife block you ever have to buy.” The heaviest model in our testing, this block was ultrastable, and its durable bamboo exterior was a breeze to clean. Well-placed medium-strength magnets made it easy to attach all our knives, and a rotating base gave us quick access to them. One tiny quibble: The blade of our 12-inch slicing knife stuck out a little.
Schmidt Brothers Downtown Block
This roomy block completely sheathed our entire winning knife set using just one of its two sides—and quite securely, thanks to long, medium-strength magnet bars. Heavy, with a grippy base, this block was very stable. An acrylic guard made this model extra-safe but also made it a little trickier to insert knives and to clean; the wood block itself showed some minor cosmetic scratching during use.
Schmidt Brothers Midtown Block
This smaller version of the Downtown Block secured all our knives nicely, though the blade of the slicing knife stuck out a bit. With a base lined with grippy material, this block was very stable. An acrylic guard afforded extra protection against contact with blades but made it a little harder to insert knives and to clean; the wood itself got a little scratched during use.
Swissmar Bamboo Magnetic Knife Block
This small, scratch-resistant model had a stable, rubber-lined base and could hold all our knives, though the blade of the 12-inch slicing knife stuck out a bit. But inch-long gaps between its small magnets made coverage uneven and forced us to find the magnetic hot spots in order to secure the knives. Its acrylic guard made it safer to use but harder to insert knives and to clean.
Messermeister Walnut Magnet Block
This handsome block was done in by its shape—a tippy, top-heavy quarter-circle that wasn’t tall or broad enough to keep the blades of three knives from poking out. It lacked a nonslip base, and its extra-strong magnets made it unnerving to attach or remove our heavy cleaver. Finally, it got a bit scratched after extensive use.
Epicurean Standing Knife Rack 12"
This magnetic block sheathed all our knives completely, though with a bit of crowding. But it was hard to insert each knife without hitting the block’s decorative slats on way down, and because the block was light and narrow, it wobbled when bumped. Worse, we couldn’t take it apart, so splatters that hit the interior were there to stay. Additionally, the outside stained easily, and when we wiped it down, the unit smelled like wet dog.
Kapoosh Rondelle Knife Block
This model stabilized knives with a mass of stiff, spaghetti-like bristles that shed and nicked easily after extensive use, covering our knives with plastic debris. While all our knives fit securely, several of the blades stuck out, making this unit feel less safe overall. Finally, though the bristles could be removed and cleaned in the dishwasher, their nooks and crannies made this block hard to wash by hand.
Kuhn Rikon Vision Knife Block, Clear
This plastic block required us to aim each knife into the folds of an accordion-pleated insert that was removable for easy cleaning but got nicked easily with repeated use. Because we could only insert the knives vertically, longer knife blades stuck out; a cleaver was too wide to fit. The lightest model in our lineup, this block was dangerously top-heavy when loaded with knives.
