“The taste of sashimi is determined by the quality of fish and the way you cut it,” fish monger Narito Ishii from GetFish at Sydney’s Fish Market tells SBS Food.
Ishii has been in the industry for over two decades, providing fresh seafood to Japanese restaurants around Sydney.
“The rule of thumb when cutting sashimi is to keep the fish cells [as] intact as possible.”
Regardless of the cutting style, you should follow two simple rules below.

Always cut sashimi against the grain for more tender slices. This means slicing across the grain to make the connective tissues shorter. If you cut along the grain, your sashimi will be stringier.
Pull not push
Sashimi is cut using one pulling motion (drawing the knife towards you). Pull the length of the knife through the fillet, starting at the bottom of the blade. You should never push and pull.

Cutting style
There are two ways to cut sashimi, depending on your preference and the type of fish you are using.
“Hira-zukuri is the most common cutting style, easy for beginners,” says Ishii.
In hira-zukuri, sashimi is cut from the right end of the saku or the sashimi block, working your way to the left.
Hira-zukuri gives you a thick, rectangular slice and is suitable for both red and white fish.

“This is recommended for white fish with firmer flesh, like snapper.”
Not only does sogi-zukuri bring out the fish's unique texture, but having a broader cross-section makes it suitable for carpaccio and any marinated dishes, as the flavours will infuse easily.

The Knife
"The best knife to cut sashimi is, of course, a sashimi knife or Yanagiba designed to do just that," Monty Govender from Boatshed Gifts at the Sydney Fish Markets tells SBS Food.
These are razor-sharp and allow for delicate, intricate work. However, depending on the range, these carry a hefty price tag, from a few hundred to thousands.
While these are tools worth investing in for chefs and the like, he says a fillet knife or any sharp knife with a thin long blade should do the job.

How to pick and store sashimi
Always check that it is "sashimi grade," as some are not suited for raw eating.
The fish market is the best place for sashimi, as these fish are handled 'separately' from the fillets, says Ishii.
"This is not to say that fish in local stores are not fresh. But they are often handled roughly and can damage the cells."
Also, check that the colour is vibrant and the fillet is plump.
"You can also determine the freshness of tuna by looking at the blood line. When it is fresh, it has a bright reddish-black color, but as it loses freshness, it gradually darkens in color."
If unsliced and stored correctly, saku can stay sashimi quality for up to 3 days.
"Moisture is the enemy," says Ishii.
"Wrap your block in a paper towel, then glad wrap. It is even better to keep them on a metallic tray in the chill section of your fridge."

"At a time when everything is costly, you can enjoy sushi and sashimi at home at a fraction of the price of eating out."
