What Is a Boning Knife Used For? Uses, Grip and Care

A boning knife is used to cut raw meat, poultry and fish away from the bone. Its narrow, pointed blade follows bones and joints closely, and it is also the knife for trimming fat, sinew and silverskin. If you’re shopping for one, my best boning knife guide has my picks.

Due to its design, it’s not always easy to find proper usage for a boning knife. For one, it looks quite out of the ordinary. Yet, there is a good reason for this particular shape.

A boning knife’s blade is narrow, thin and sharp, and it comes flexible, semi-flexible or stiff. Flexible blades suit fish, poultry and silverskin; stiff ones suit beef and pork. That makes cutting with this knife a much easier affair compared to the usual ones. As for its ‘specialty’, a boning knife can effortlessly detach raw meat from the bone. Keep it sharp: dull blades may rip the meat off the bone rather than slice it. That wastes meat and spoils the look of the dish.

Today, we’ll go through the common usages of a boning knife and share tips on how to use it as a chef.

What Is a Boning Knife?

To begin, let’s clarify what a boning knife is and how it’s built. Only then can we summarize its range of appliances.

Let’s start with the obvious attribute: its slick appearance. A boning knife consists of a narrow, thin, sharp blade, usually five to seven inches long. The knife features a stainless steel blade edge with a small slope up to its sharp tip. Thankfully, there is an extra safety feature that goes well with this much cutting power. Namely, many have a little finger guard to protect your fingers from accidents during cutting. All this makes the boning knife easy to identify and effective to use.

How to Use a Boning Knife Correctly

A boning knife’s signature shape makes it somewhat tricky to handle. The narrow, often flexible blade differs from the majority of kitchen knives. However, that’s not to say that boning knives are unwieldy. As is with other higher-class equipment, you can even master it with enough time and practice. Start by holding the knife in your dominant hand with a firm and secure grip: wrap your middle, ring and little fingers and your thumb around the handle.

To keep the piece of meat or fish stable on the chopping board, use your non-dominant hand to press it down. At all times, avoid cutting yourself by keeping your fingers curled. Rest your index finger on the spine of the blade (the blunt top edge) to steady and guide each cut. Use the boning knife’s pointed tip to create little cuts in your meat. Keep your hand and handle dry, because a greasy handle is the most common way to slip.

The Top Usages of a Boning Knife

Removing the Bones From the Meat

Evidently, a boning knife’s main purpose is to remove the bones from the meat precisely. However, the specifics of how you will go about doing so depend on the meat in question. In general, though, consider the pointers in the following section.

Put the meat on a chopping board and use a knife to locate the bone. For this, it may be necessary first to remove a bit of fat or skin. Then, using the tip of the knife, trace the contour of the bone with the blade. This will enable you to create a shallow but exact incision into the flesh, preparing for the next step.

Then, place the blade into the incision you created and work along the bone with short strokes, keeping the edge angled slightly toward the bone so the meat stays on the meat side. Pull the meat back with your other hand as you go so you can see the bone. Let the sharp edge do the work rather than force, and never twist the blade against bone. Repeat until the bone comes free. This works best on raw meat; cooked meat usually pulls off the bone more easily.

Remove Skin, Fat and Silverskin

Put the meat on a cutting board with the skin, fat cap or silverskin facing up. Next, using the edge of your boning knife, create a tiny incision as close to the meat as possible without cutting it. To do this, you might have to cut away a little flap of skin up to one or two inches in length.

Then, with care, keep that flap of flesh in place and delicately slide the length of your boning knife’s blade along it. At that point, divide the skin away from the flesh with long, shallow strokes, the edge tilted slightly up toward the skin and the flap pulled tight.

If you look attentively, you’ll find that the skin is tightly wrapped around the flesh. Hence, you will need to position your boning knife correctly so that the edge can reach every curving of the skin. This is the most efficient way to separate the flesh from the skin thoroughly.

Extracting the Skin From a Fish Fillet

Even though a boning knife is not the same as a fish fillet knife, it does make for an excellent substitute. In other words, you may still remove the fish’s skin using only a boning knife. It might take some getting used to, but the process will not be that much different.

Start by placing the fish on a chopping board with the skin side down. Then, simply make a little cut between the meat and the skin with the point of the knife. It is essential to aim carefully, sticking tightly to the edge of the skin.

Using your other hand, grip the tail end of the skin (a pinch of salt on your fingers helps) and pull it gently while you slide the knife along with the edge angled slightly down toward the skin. During that, remember to go slowly so as not to ruin the delicate flesh. Maintain this motion until the skin entirely detaches from the fillet.

Inscribe Your Fruits and Veggies

Because the boning knife’s blade is so sharp and narrow, it may be used for small carving jobs, like coring tomatoes or peppers or cutting the rind off a melon.

However, we recommend that you use some more standard types of knives for those purposes. As a rule, boning knives are best when it comes to meat or fish-based dishes. For other purposes, you should handle them very carefully. Once you understand this principle, feel free to experiment and be creative.

Cut That Cake

Surprisingly enough, you can use your boning knife even when baking. Make use of the pointed tip of a boning knife and treat it as a cookie-cutter when in a hurry. Furthermore, use the blade to slice a hole in the center of a cupcake before filling it with frosting. Finally, you could use the pointed tip and sharp, flat blade to sculpt the exterior of a cake. In these ways, you can produce some trendy-looking sweets in no time.

Instructions on How to Clean a Boning Knife

It is advisable to clean and dry your cutlery by hand after every use. Even though most knives are made of stainless steel and are generally sturdy, the dishwasher dulls the edge, and water may swell and deform wooden grips. It can also seep into cracks and do some damage later on. Wash it with warm soapy water right after cutting raw meat, then dry it fully. When the edge stops gliding along the bone, it is time to sharpen your boning knife.

Wrapping Up

A boning knife is a versatile tool that holds many potential uses. Its slick build and razor-sharp blade contribute to its precision. So, keep one around for every delicate meat and fish job. If you’re shopping for one, my guide to the best knives for trimming meat compares the main options.
