You might not recognize this. If you do, you must be older.

The item shown is a vintage ROWOCO stainless-steel citrus zester (often described as a zester/peeler/curler). It’s designed to remove thin, aromatic strips of citrus peel—mainly the colored outer layer (the “zest”)—to add fragrance and flavor to food and drinks. Many vintage versions are marked “ROWOCO” and often include “Inox” (a common marking indicating stainless steel).

What This Tool Is Used For
This type of zester is best for producing narrow ribbons of zest that naturally curl—ideal for garnishes and baking.

Common uses include:

• Zesting lemons, limes, oranges, and grapefruit for recipes
• Creating citrus twists/curls for cocktails and mocktails
• Adding zest to cakes, cookies, custards, sauces, and marinades
• Making garnish strips for plated desserts and savory dishes

Key Design Features (Based on the Tool in the Photo)

• Stainless-steel head with a flat, rectangular body
• A row of semi-circular cutting holes at the top edge
  • These holes act like a channel zester, shaving thin strips of peel
• Ergonomic black handle for a secure grip and controlled pressure
• Compact and sturdy construction typical of older kitchen tools

How It Works (Simple Step-by-Step)

1. Wash and dry the citrus fruit.
2. Hold the fruit firmly.
3. Place the tool’s cutting holes against the peel.
4. Pull the tool across the peel in one smooth motion.
5. The tool will remove thin strips of the colored outer layer.
6. Use immediately or store zest briefly in an airtight container.

Important tip: Aim to remove only the colored outer peel. Avoid pressing so hard that you dig into the white pith, which can taste bitter.

Best Results: Practical Tips

• Choose fruit with a firm, glossy peel (it zests more cleanly).
• Use light, even pressure to get fragrant zest without bitterness.
• Rotate the fruit as you go so you only take the outer colored layer.
• If you want curls for garnish, pull longer strokes to form longer ribbons.

Zester vs. Peeler: What This Tool Does Best
Although sellers may call it a “peeler,” this tool typically does not create wide peel sheets like a classic swivel peeler. Instead, it excels at:

• Fine zest strips for flavoring
• Decorative curls/twists for presentation
• Small, controlled garnishing where precision matters

Cleaning and Care (Especially for Vintage Pieces)
To keep a vintage stainless tool in good shape:

• Rinse shortly after use (citrus oils can leave residue).
• Wash by hand with mild soap and a soft sponge.
• Use a small brush (like a toothbrush) to clean the cutting holes.
• Dry fully to prevent water spots and protect any stamped markings.

Avoid:

• Letting it soak for long periods
• Abrasive scouring pads that can scratch the metal
• Dishwashers (often harsh on older handles and finishes)

Safety Notes
Even though it’s small, the cutting edge can be sharp.

• Keep fingers clear of the cutting holes when pulling the tool.
• Store it so the head isn’t rubbing against other utensils.

Why Vintage Kitchen Tools Like This Are Popular
Vintage zesting tools remain useful because they are:

• Simple and efficient (no moving parts)
• Often made with durable stainless steel
• Great for classic garnishes that never go out of style
• Collectible—especially when clearly marked ROWOCO and France

What Collectors and Buyers Look For
If you’re listing or evaluating one, these details matter:

• Visible brand stamp (e.g., ROWOCO, sometimes Inox)
• Clean, intact cutting holes (not bent or clogged)
• Handle condition (no cracks, chips, or looseness)
• Overall finish: light wear is normal; heavy corrosion is not
