First, Ripert travels almost constantly and much of his cooking is done on television or before an audience. Indeed, as you can see from the contents of the case, he travels with far more than just his knives, but includes other tools that may not be available in such situations. It's not like he's a line cook at Le Bernadin.
Second, keeping one's knives secure and in good condition is an attribute that every chef or even home cook should possess. These are essentials of the profession. Most of us eventually find knives that are just right for us and maintaining them properly (ie...not leaving them around in a kitchen where they can be used by others, damaged or stolen) is a pretty basic concept.
Third, setting aside the outside appearance, the actual interior construction of the case looks quite well thought out, practical, and secure.
Third, if the same case were made of Russian calf by the boys at Cleverley or by Tony Gaziano in burnished calf or maybe even Alden in cigar-shaded cordovan, the shoeguys on this Forum would be gushing all over the place.
Fourth, anything by LV would be gauche to many on this Forum (for rather good reason) but my guess is that this was really a professional arrangement rather than just a personal style choice by M. Ripert.
