Material & Structural Design

1. Thickened one-piece stainless steel construction Made of premium solid stainless steel with integral stamping molding, the tool features sturdy thickness to resist bending and permanent deformation even after frequent heavy-duty shell breaking work. Brushed polished surface delivers excellent rust and corrosion resistance, safe against seawater and seafood juice erosion, easy to rinse clean for long service life in home kitchens and Japanese restaurants. All edges are smoothly deburred to prevent hand scratches during operation.

2. Labor-saving A-shape lever principle Adopts classic A-type lever structure to amplify pressing force dramatically. Users can crack tough spiky sea urchin shells with minimal effort, greatly reducing hand fatigue for bulk commercial processing. The solid rivet pivot ensures stable smooth opening and closing without wobbling or falling off.

3. Exclusive inner hook mouth positioning notch Specially designed concave hook bayonet locks the curved sea urchin shell firmly to avoid slipping while cutting. Controlled cutting depth only splits the hard outer spine shell without piercing the precious internal uni (sea urchin roe), maximizing intact meat yield and reducing waste.

Key Functional Advantages

1. Safe operation away from sharp spines Sea urchin thorns are extremely sharp and easy to pierce bare fingers. The long handle keeps your hands far from dangerous spines, effectively preventing stabbing injuries during shell opening for full protection.

2. Super easy operation for beginners Simple working steps: Locate the top opening of the sea urchin → clamp the shell edge with the hook notch → squeeze two handles to apply lever pressure → pry open the shell directly. No professional skills required.

3. Sanitary effortless cleaning Integral bent design has no narrow gaps to trap seafood residue, slime or dirt. Just rinse under running water, air dry for storage, no odor or bacteria buildup.

4. Space-saving compact storage Flat slim profile can be stored flat in kitchen drawers or hung on wall hooks, perfect for small home kitchens and commercial back-of-house storage.

Wide Application

· Household DIY: Homemade sashimi sea urchin, steamed sea urchin preparation

· Commercial catering: Japanese izakaya, seafood restaurants, wet market bulk sea urchin processing

· Emergency alternative: Minor opening for small shellfish and crab hard edges

Usage Notes

1. Cut from the top excretory opening of the sea urchin for easier breaking and better roe protection;

2. Rinse thoroughly and dry completely after each use to extend service life;

3. Only for seafood shell opening, do not pry hard bones or rigid objects to avoid deformation.
