Which exact version is this?

5.2063.20, black TPE handle, extra-wide straight edge

What does Victorinox design this Fibrox to do?

Victorinox identifies chopping, dicing and slicing as uses for this extra-wide chef blade. Its maker page names an ergonomic, non-slip TPE handle. The straight-edge 5.2063.20 record lists a non-forged blade, so a forged Fibrox listing would need its own identity check.

How does this model fit the kitchen comparison?

The maker lists a 7.9-inch blade and 13.4-inch total length; an 8-inch retailer label is not a replacement for those fields. At 6.4 oz, this is the only one of the four new chef candidates with a published weight in the opened maker records. Compare the chef formats and board space before reading its dated retailer offer.

What should I check before choosing?

This is the black extra-wide straight-edge knife. The Fibrox slicing, cimeter, carving and bread variants are excluded. Published dimensions cannot establish hand comfort.
