Learning how to prepare delicious cuts of meat is one of the most rewarding processes one can go through. Whether you’re just starting to grow your collection or are a seasoned pro at this point, you’ll need a decent boning knife to get the job done. The question is, which knife should you go for? This article will explore the curved VS straight boning knife debate. 

We’ll cover what boning knives work well for, what makes each type of boning knife stick out, and how to make a decision that works for you and your kitchen. 

What is a Boning Knife?

If you’re reading this article, you’re probably au fait with kitchen tools already, but we’ll briefly explain boning knives here in case you’re a budding knife aficionado.

If you’re separating raw meat from the bone, you’ll probably need a boning knife. They’re typically quite flexible and thin with a sharp point to make it easier to pierce the flesh and cut through ligaments and other connective tissue. A decent boning knife doesn’t have to be expensive and it’s well worth the investment in our opinion. 

The main two types of knives in this category are straight and curved. We explore the differences between curved VS straight boning knives below. 

Straight Boning Knife Overview

As the name suggests, straight boning knives feature a straight, thin, and typically quite sharp blade. While they’re often a bit more flexible than a regular chef knife, they’re more rigid than their curved counterparts. 

This will either be a boon or a burden depending on your specific use case. Read on to discover which applies to your collection. 


The advantage of using a less flexible blade is that you’ll typically have a sharper knife at your disposal. For tougher or thicker cuts of meat, this can be a real Godsend. If sharpness is a priority for you, a straight boning knife is probably worth considering. 

If you’re brand-new to deboning cuts of meat, there’s one thing to be ready for with a straight boning knife – meat wastage. The less forgiving blade can cut a bit inaccurately at first. Don’t worry too much though – you’ll be up to speed in no time. 


Another bonus when using a straight boning knife is that they’re usually pretty straightforward to sharpen. With a straight blade, you won’t have to worry too much about getting the right angle or maintaining the edge you’re looking for. 

With curved boning knives, this can be a little trickier.

Piercing Action

A mark of a good boning knife is how well it pierces into thicker cuts of meat. With a high-quality straight boning knife, you should be able to pierce, cut, and partition off meat to your heart’s content. While curved boning knives are fantastic in the right context, straighter options are usually better at making those first few incisions. 

Tough and Precise Cuts

When you increase the sharpness of a blade, you increase the ease with which you’re able to slice through meat. If you’re preparing tougher cuts like beef, pork, or lamb, a straight boning knife might be a safe bet for you. They’re typically much better at this kind of work. 

Provided you’re cutting with straight lines, this kind of boning knife can also be much more precise. If you have the requisite skills that is.

Curved Boning Knife Overview

As you probably guessed, curved boning knives feature a curved blade and slightly more flexibility than straight boning knives. This means that the average sharpness and HRC on offer is likely to be lower, but this is far from a bad thing in the right context. 

When deboning certain cuts of meat and seafood, you actually need some flexibility to be able to reach those tricky corners and cut through those stubborn pockets of fat. For this reason, curved boning knives are loved by pro chefs around the world. The good news is there are tons of options out there to add to your toolkit.

Tricky Cuts 

If you’re working with poultry, fish, or seafood, a curved carving knife is probably the way to go. A curved blade with a bit of flexibility makes it much easier to prepare cuts of meat without damaging them. This is particularly noticeable with more delicate seafood. 

Delicate Prep Work 

With a bit of skill and a curved boning knife, you’ll never bruise or damage your filets again. Removing the bones from delicate fish calls for the accessibility and accuracy that comes with this kind of kitchen tool. 


One thing to keep in mind with curved boning knives is that they can be a touch trickier to sharpen than their straight counterparts. Don’t get us wrong – it’s not rocket science to keep a curved knife sharp. It just takes a bit more patience and the right tools. 

Depending on the angle and direction of your blade’s curve, a round-edge sharpening tool may help.
