Mandolines, vegetable cutters and knife blocks

A badly cut vegetable cooks badly, and it is the most common reason a dish fails without anyone knowing why. Pieces of different thickness never finish together: when the small ones are done the big ones are raw, and the reverse if you keep going. Evenness of cut therefore matters more than the heat.

Hence the value of a guided blade. A mandoline does not cut better than a good knife in a good hand — it cuts **the same on every pass**, which no hand does over a kilo of carrots. The gain is not speed, it is consistency.

The second subject of this aisle is keeping the edge. A knife loses its sharpness mostly in the drawer, knocking against other utensils — not while cutting. An open block, where blades never touch and dry in the air, extends a knife's life far more than the occasional sharpening.

And the third, easily forgotten: what cleans badly ends up unused. Between fork tines, inside a cutter's slots, under a scaler's cover. A tool you give up washing goes to the back of the cupboard.
