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.

What's under the silicone
Cut most silicone utensils open and the story changes. Ours is the same inside and out.
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.
