Funayuki Vs. Petty: Which Knive Is Better?

Japanse kitchen knives are all made to have a particular set of skills that make them great for certain functions in the kitchen. However, some of these characteristics make them great for specific tasks but then make them not so useful for functions that are outside of their normal task set. So between the Funayuki and the Petty, which knife would be better?

The Funayuki knife is an all-purpose knife for processing fish, meat, poultry and for slicing and chopping vegetables and fruit. The Petty is better for peeling fruit and vegetables, chopping herbs, and processing these ingredients delicately for decorative purposes. Overall the Funayuki is a better choice.

The Funayuki and the Petty are both considered to be small to medium size knives in the Japanese kitchen knife range.

Given that the two knives in question can be similar in size, could you choose one over the other and use it to cover the intended purpose of the other knife? Another question that can be asked is that if you can only get either the Petty or the Funayuki, which would be the best knife to choose?

Intended Purpose Of The Funayuki And The Petty

If you have had much to do with Japanese kitchen knives, you will know that each style of knife is designed and constructed with a particular purpose in mind.

The main features of the knife are designed to make the knife perfect for its intended purpose, but such a focused design could make the knife impractical for other kitchen tasks.

  • The purpose of the Funayuki.

The Funayuki was designed as a hardworking, robust knife that was used by fishermen onboard their fishing boats. The design was intended to be multi-purpose for cleaning and processing fish as well as used for preparing meals for the fishermen on the boat.

This means that the knife is useful for dressing fish, slicing up smaller cuts of meat, and for limited chopping and slicing of vegetables. 

  • The purpose of the Petty knife.

The Petty is the Japanese version of the western utility knife. The Petty is designed for small, delicate cutting and slicing on a cutting board. It is also used for peeling fruit and vegetables, shaping them decoratively, chopping herbs, and making garnishes.

The Spine Of The Knife

The spine of the knife is the top of the blade, and the thickness and shape of the spine vary depending on the intended purpose of the knife.

  • Funayuki spine.

The spine of this knife is more robust than that of the petty, which adds weight to the blade, making it suitable for the purpose of processing fish and meat cuts as well as some light chopping tasks.

  • The Petty spine.

The spine of the Petty is thinner than that of the Funayuki, which makes the blade light and more nimble for the delicate work that the knife is intended to be used for.

The Belly Of The Blade

The belly of the blade in the shape of the cutting edge of the knife and whether it is straight and flat or has a curvature to it.

  • Funayuki belly.

The Funayki knife has a slight belly, which curves up towards the tip of the knife in the last third of the length of the edge. This shape lends itself to the rocking chopping motion used to chop with the heel of the knife.

  • The Petty belly.

The Petty, in most cases, has a flat straight edge with little to no belly curve to the blade. This is because the knife is not intended to be used with a rocking motion for chopping with the heel of the knife.

The flat edge makes it ideal for slicing, peeling, and delicate work, mostly with the front section of the cutting edge of the knife.

The Bevel Of The Blade

The bevel on a knife is either single or double. A single bevel only has one side of the blade ground into the steel, tapering the blade towards the edge.

A double bevel is ground equally on both sides, tapering both sides of the blade towards the sharp edge. Single bevels are more difficult to maintain than double bevels.

  • Funayuki bevels.

A Funayuki can be either a single bevel or double bevel, but it is more common with a double bevel.

  • Petty bevels.

The petty is almost always a double bevel knife.

The Body Of The Blade

This is the overall shape and dimensions of the blade that makes it suitable for certain purposes.

  • Funayuki blade body.

The funayuki blade is tall and has a much beefier appearance than the Petty. This is to provide more weight behind the blade to give it the mass to easily cut through more robust ingredients such as meat, fish, and harder vegetables.

  • The Petty blade body.

The Petty has a slender blade that reduces the amount of weight in the blade and makes it nimble, which promotes the ease of use for delicate, fine work with the blade.

The Handle Of The Knife

The shape and weight of the handle of a knife are integral to the purpose and manner in which the knife is intended to be used.

In the majority of traditional Japanese kitchen knives, a hidden tang style of handle is used to produce a lighter weight handle and put the central balance point of the knife further forward on the blade of the knife, rather than in the center of the knife.

This gives the knife user more control over the blade and promotes a grip closer to the blade of the knife. A traditionally hidden tang and the traditional Japanese-shaped handle is termed a Wa handle. These handles are also easily replaced should they crack or become damaged.

  • Funayuki handle.

The Funayuki has a traditional hidden tang Wa handle on the knife.

  • Petty handle.

The Petty can have a Wa handle or a western-style handle.

The Weight Of The Knife

The weight of a knife will determine how deftly the user can wield the knife, and usually, knives intended for fine, delicate work will be more lightweight than knives intended for more heavy-duty work.

  • Weight of the Funayuki.

The Funayuki is a lightweight knife compared to other Japanese kitchen knives, but it has sufficient weight to be useful for light to medium-duty work in the kitchen. The Funayuki is certainly a heavier knife than the Petty.

  • Weight of the Petty.

The Petty is a very lightweight knife due to the need for the blade to be quick and nimble on the lightweight tasks that it is intended for in the kitchen.

If you are looking for a Japanese kitchen knife, our recommendation is to go with the Fuanyuki. The Funayuki is often described as a mini Gyuto or chef’s knife, which is a testament to the versatility of the Funayuki in the kitchen. 

While a Petty is nice to have, the tasks that this knife performs in the kitchen can be done by a western-style paring or utility knife, which would be a cheaper purchase.

For these reasons, the Funayuki would be the better choice of the two knives, and you would get the most out of it in the kitchen because it can handle a wider range of kitchen tasks.
