That mystery “comb-like” object is an onion slicer holder, also called a vegetable slicing guide, onion holder, or onion fork. Similar versions are specifically designed with multiple stainless-steel prongs to hold an onion or other food securely while you slice alongside the prongs. shoppingway+1
🔪 How to Use It
- Peel the onion and cut off the ends.
- Place the onion on a stable cutting board.
- Hold the tool by its handle.
- Push the metal prongs into the onion.
- Keep the prongs positioned where you want your slices.
- Use your knife to cut between the prongs.
- Continue slicing while the holder keeps the onion steady and your fingers farther away from the knife.
The spacing between the prongs helps you make more uniform slices, while also giving your knife a guide. Laptab+1
🥔 It’s Not Just for Onions
Depending on the particular model, these holders can also be used with foods such as:
- Potatoes
- Tomatoes
- Carrots
- Cucumbers
- Garlic
- Lemons
- Other firm fruits and vegetables
Some versions are even marketed as meat tenderizers, although I would check the construction and manufacturer’s instructions before using a thrift-store utensil for raw meat. Duly Kitchen+1
🧼 Since Yours Came From a Thrift Store
Before using it with food, give it a thorough wash with hot water and dish soap, paying particular attention to the areas around the prongs and handle.
Check the metal for rust, pitting, loose parts, or damage. If the handle is cracked or the prongs are badly corroded, I’d replace it rather than risk using it.
🌟 The Fun Part
So your “comb-looking thing” actually has a very practical purpose: it holds an onion or vegetable securely and helps guide your knife for safer, more even slicing. Similar products are currently sold specifically as onion/vegetable slicing holders. Laptab
