The HOSHANHO chef's knife costs £31.44 and is rated 4.6 stars from 2,471 ratings, in Japanese 10Cr15CoMoV steel with a wooden handle.

It takes fourth because the sample is the largest of any single knife here and the steel grade is named, while its sharpness claim has no baseline and the hard number a buyer needs is missing.

**Is it a santoku?**

No: it is an 8-inch chef's knife, despite the category badge.

**Is it dishwasher safe?**

The listing says yes, though hand washing protects the edge.

**Why is it fourth?**

Because the evidence is the strongest of the single knives, but the claim is unmeasurable.

2471 at the time of collection, averaging 4.6 stars, with 81 per cent five-star and 3 per cent one-star.
