What is a kitchen mandoline used for and why safety matters
A kitchen mandoline is a manual tool that slices vegetables and fruits into even slices, rounds, or julienne strips. But the blade remains exposed, and that is where everything is at stake.
A kitchen mandoline turns a chore into a fluid motion. Ten minutes of cutting becomes two. The slices are identical, so cooking is even. That is the real argument.
The downside: the blade is very sharp and often poorly protected during use. Most accidents happen with bare fingers, on a slipping food item. The rule is simple: never push food by hand onto a blade.
How to use a mandoline without cutting yourself: the 6 key steps
Safety depends on six actions, in this order. Skip a step and the risk increases immediately.
Step 1: prepare and stabilize the mandoline
Place the mandoline on a stable, flat, and dry surface. The non-slip feet must adhere completely. A damp cloth under the base adds grip on a smooth countertop.
Check that nothing moves before cutting. A slipping mandoline is the leading cause of cuts.
Step 2: install the blade and set the thickness
Install the adjustable blade until it clicks firmly. Choose the cutting thickness before starting, not halfway through. Setting a kitchen mandoline with your fingers near the blade is a classic mistake.
- V-blade: clean and even slices
- Julienne blade: sticks for carrots and zucchini
- Thin thickness: carpaccio, chips
- Medium thickness: gratins, rounds
Step 3: slice with a steady motion
Place the food in the pusher, then guide it with a steady motion. Maintain constant pressure, without jerking. The free hand remains on the handle, never above the blade.
Slice all the way through, then lift back up. Consistency matters more than speed.

The mandoline safety pusher: why it is not optional
The mandoline safety pusher is the piece that holds the food and keeps your fingers away from the blade. It is not an accessory, it is a condition of use.
A finger guard does two things: it holds the food firmly and it absorbs the pressure for you. In the last few centimeters, it does the work, not your fingers. Hand protection depends entirely on this piece.
How to set a kitchen mandoline for each type of food
The setting depends on two factors: the firmness of the food and its shape. A soft or round food item slips more easily than a firm, long carrot.
| Food | Recommended thickness | Why this setting | Safety tip |
|---|---|---|---|
| Potato | 2-3 mm | Firm, it holds well in the pusher; a slice too thin catches the blade | Pusher mandatory, never finish by hand |
| Cucumber | 1-2 mm | Round and slippery, it spins in the pusher if the thickness is too large | Remove the ends, place skin-side up in the pusher |
| Carrot | 2 mm or julienne | Long and firm, it stabilizes well; julienne requires a dedicated blade | Cut into 5-6 cm pieces to prevent the carrot from tipping |
| Zucchini | 2 mm | Tender, it crushes if the pressure is too strong | Slice lengthwise, light and steady pressure |
| Onion | 1-2 mm | The layers separate and slip; a fine setting limits vibrations | Hold firmly in the pusher, cut the ends off first |
| Fennel | 2 mm | Fibrous, it offers resistance that can cause the mandoline to slip | Stabilize the base with a damp cloth, slow motion |
Set the thickness once, before starting. Changing the setting between two foods multiplies the manipulations near the blade. On dial models, turn the dial until the desired notch and check that the blade is properly locked: a firm click indicates that the setting is in place. On lever models, push the lever all the way into the chosen position.
For very soft foods (tomato, mushroom), set to a larger thickness (3-4 mm) and apply very light pressure: the blade should slice, not crush. For very firm foods (celeriac, sweet potato), a medium thickness (2-3 mm) limits the effort and the risk of slipping.
Small pieces and short foods: solutions when the pusher is no longer enough
The last few centimeters of a food item are the most dangerous zone. The pusher no longer grips enough, and the urge to finish by hand arises. Resist.
- Finish the piece with a knife, on the cutting board
- Use a second, smaller pusher if your model offers one
- Group small pieces in a larger one to stabilize them
- Throw away the remaining piece that is too short rather than risking a finger
How to clean a kitchen mandoline without injuring yourself
Cleaning is the second risky moment. You handle the bare blade, often in soapy water, and that is where cuts happen. Here is the complete procedure, from disassembly to storage.
1. Disassemble without forcing. Follow the manufacturer's instructions. On most models, the blade is removed by unlocking a latch or sliding the support. Never pull on the blade itself: take the support by its non-cutting edges.
2. Remove the blade by taking it by the non-cutting edge. Grip the blade by the back or by the support, never by the edge. Place it immediately flat on a cloth, edge up, to prevent it from slipping.
3. Clean with a brush, not a sponge. Use the provided brush to remove residue without bringing your fingers close. For models without a brush, a soft-bristle toothbrush does the trick. Rinse with clear water, then dry completely before storing: a damp stored blade wears out faster and can rust.

4. Rinse and dry each piece separately. Do not leave blades soaking in the sink: you forget them and cut yourself when retrieving them. Dry immediately with a clean cloth, by dabbing, never by wiping the edge.
5. Secure storage. Put the blade guard back in place before storing. Store the mandoline flat in a drawer or hanging by its hole, blade facing inward. Never leave it with the blade exposed in a drawer where you rummage. If your model does not have a blade guard, store the blade in its case or wrapped in a thick cloth, separate from other utensils.
What to do in case of a cut: first aid
A mandoline cut often bleeds a lot and deeply. Stay calm and act in order.
- Rinse the wound with clear water
- Compress with a clean cloth for several minutes
- Elevate the hand above the heart
- Protect with a sterile bandage
If the cut is deep, if it does not stop bleeding, or if a tendon or nerve appears to be affected, consult a healthcare professional without delay. For first aid steps, refer to the official recommendations of the French Civil Security.

Frequently Asked Questions
How do you hold food when cutting it with a mandoline?
Always use the pusher or finger guard provided with your kitchen mandoline. Place the food in the pusher's cradle, close the lid, and hold it firmly while cutting. This keeps your fingers several centimeters away from the sharp blade. For round foods such as tomatoes or cucumbers, first cut a thin slice from the base to create a flat surface, then insert them into the pusher. Never guide the food with bare fingers, even for the last slices.
Should you always use a mandoline's safety pusher?
Yes, without exception. The mandoline safety pusher is the accessory that holds the food while keeping your hands away from the blade. Even experienced cooks cut themselves trying to save time on the last few slices. On V-blade models such as the V-Blade Kitchen Mandoline with Finger Guard (€11.99), the finger guard is included and also designed to hold firm foods. If your mandoline does not have one, get one before the first use.
How do you set the cutting thickness on a mandoline?
Most manual mandolines have a lever or dial under the blade that adjusts the distance between the blade and the cutting plate. Turn the setting before you start: 1 to 2 mm for carpaccio and chips, 3 to 5 mm for gratins and salads, and thicker for slices to pan-fry. Test on a piece of carrot to check the thickness achieved. Never change the setting while cutting, with the blade exposed: first remove the food and disassemble if necessary.
How do you clean a mandoline without injuring yourself?
Disassemble the mandoline according to the instructions: remove the detachable blade by grasping it by its non-cutting edge or the provided handle. Rinse the blade under warm water using the provided cleaning brush, never with your fingers or a bare sponge. Wash the body and pusher with soap, then dry immediately to prevent rust. Store the blade in its case or compartment, and hang the mandoline by its hanging hole or lay it flat in a drawer, out of reach of children.
