Product Description
The MAC Professional SO-70 is a dedicated sole fillet knife with a 17.5cm blade, designed specifically for the controlled, flat cuts required when breaking down flatfish such as sole and flounder. It is not a general-purpose fillet knife — the geometry of the blade is optimised for working close to the bone along flat-bodied fish, where a stiffer or wider blade would compromise yield and accuracy.
In a busy fish preparation environment, the quality of your filleting knife has a direct effect on yield, speed, and consistency. The SO-70 carries the characteristics MAC Professional knives are known for: a keen edge that holds well under regular use, a blade that responds predictably during fine work, and a handle that remains comfortable through extended prep sessions. Japanese manufacture and traditional hand-finishing contribute to the consistency you would expect from a professional-grade knife at this price point.
Practically, this knife suits kitchens where flatfish is a regular feature on the menu rather than an occasional special. It performs well in the hands of a trained fish cook or chef de partie who understands how to maintain an edge. A few points worth noting before buying:
- Hand wash only — not suitable for dishwasher use
- Edge maintenance requires a whetstone or appropriate sharpening steel; a honing steel alone will not suffice long-term
- The 17.5cm blade length suits medium flatfish; very large specimens may benefit from a longer blade
- Not designed as a general-purpose fillet knife for round fish — a more flexible blade is typically better suited to that task
If you are equipping a fish prep section and are unsure whether this is the right blade profile for your menu, we are happy to talk through what you are preparing and help you choose accordingly.

Frequently Asked Questions
- The SO-70 is designed primarily for flatfish such as sole and flounder, where a blade that tracks flat and close to the bone is an advantage. For round fish like salmon or sea bass, a more flexible fillet knife with a different blade profile will generally give better results. If your kitchen handles a mix of fish species, it is worth having both profiles available.
- MAC Professional knives are made from a harder steel than many European brands, which supports excellent edge retention but requires a whetstone or appropriate sharpening system rather than a standard honing steel alone. Regular honing between uses will extend the time between full sharpenings, but the blade should be properly sharpened on a whetstone when it loses its bite. Hand washing and prompt drying after use will protect both the blade and the handle.
- A specialist sole fillet knife earns its place in kitchens where flatfish features regularly on the menu. If flatfish is only an occasional special, a good-quality flexible fillet knife may offer more versatility for the investment. If you are unsure which approach suits your menu best, we are happy to help you think it through.
