Silicone Utensils with a Real Steel Core

Silicone on the outside is easy. What's underneath is the difference. Most "silicone" utensils hide a plastic stick or cheap steel that corrodes. Ours are molded in platinum silicone around a food-grade stainless steel core, fully sealed — nothing to melt, rust or flake into the pan. And if you love wood: ours is carved one-piece and finished with plants, never mineral oil.

Utensils, answered

What's inside Ziruma silicone utensils?

A food-grade stainless steel core, completely sealed in platinum-cured silicone. The steel gives them the rigidity to actually flip, scrape and fold, and because it's food-grade stainless — not a plastic stick, not mystery metal — there's nothing underneath you wouldn't want near your food.

How do I know if a silicone utensil has a plastic core?

Most brands don't say, and that silence is the answer. Signs of a plastic core: the utensil feels light and bends easily, the listing says "silicone" without naming what's inside, and the heat rating is suspiciously low. A steel-core utensil feels noticeably heavier and firmer. We name our core because we're proud of it.

Will they scratch my nonstick pans?

No. The steel core never touches the pan — it's fully sealed inside the silicone, which is softer than any cookware coating. That's exactly why pan manufacturers recommend silicone.

What finish is on the wooden utensils?

Plant-based oil and wax, nothing else. Most wooden utensils are finished with mineral oil — a petroleum derivative — because it's cheap. We don't put petroleum on something that stirs your dinner. Each piece is also carved from a single piece of wood: no glued-on heads, no joints to trap residue or snap.

How do I care for each set?

Silicone: dishwasher, done. Wood: hand wash, dry upright, and rub in a little Organic Wood Wax when it starts looking thirsty — prolonged soaking and dishwasher heat are the only things that genuinely age wood.
