An 18 cm (7.1 in) fish fillet knife in Japanese powder steel with a stated 2.2 mm (0.09 in) blade — the only thickness figure published in this hub.
What we would actually buy The published thickness is the most useful figure here, and the listing is honest that the pattern is engraved.
An 18 cm (7.1 in) fish fillet knife in Japanese powder steel, with a stated 2.2 mm (0.09 in) blade, a slight curve, and a laser-engraved decorative pattern.
2.2 mm (0.09 in), published. Blade thickness decides how much the knife has to push flesh apart behind the edge, and on a filleting knife it decides whether a fillet comes off cleanly or is bruised. No other listing in this hub gives it.
A manufacturing route that produces a very fine, even grain, which supports a hard blade with fewer weak points. The listing names the route and not a hardness, so nothing is claimed here about edge retention.
Laser-engraved, and stated as such. That is decoration on the surface of a good blade, which is a perfectly reasonable thing to sell — as long as it is named, and here it is.
On sale at around $50 on the American Amazon store at the time of checking.

A listing is not an offer: the reference exists on these stores, availability changes daily.
Steel made by consolidating powdered alloy rather than casting an ingot. It gives a very fine, even grain, which allows a hard blade with fewer weak points. It is a manufacturing route rather than a specific grade.
It is decoration, and stating it plainly is the honest thing to do. What matters is the steel underneath, which this listing names.

Close prices, same category: comparable cookware and knives. We keep only the specifications all of them publish, because a column with gaps compares nothing.
