The title and the bullets disagree
Title: “12 Blade”. Bullet two: “With nine interchangeable blades” — and then, truncated, “Make use of the 3 bla[des]”.
Nine plus three is twelve, so the arithmetic probably works. But you have to do it yourself, and a cut-off bullet is a poor place to settle a headline number.
For comparison here: Mueller’s own Vegetable Chopper states six blades, Mueller Austria five, Benriner one fixed plus three interchangeable.
And it is three tools in one body
Worth being clear which you are buying.
A mandoline is a fixed blade in a flat runway: you slide the vegetable along it, one slice per pass, thickness set by how far the blade stands proud.
A push-down chopper is a grid of blades in a frame: bring the lid down on half an onion and the whole thing dices into a box below.
A spiralizer is a third mechanism again — a rotating cut that makes long ribbons.
This does all three. That is the appeal, and the compromise: a device that dices, slices, juliennes, grates and spiralizes is excellent at none of them beside a dedicated tool.
The mandolines proper on this shelf are the Benriner, the three OXO units and the Gramercy.
What it does have that nothing else here does is the spiralizer — a tool people otherwise buy separately.
Twelve blades, and where they live
The real cost of a twelve-blade set. Each one is a razor-sharp item, and the universal experience is that the blade you want is the one that has gone missing — or worse, the one you find with your fingertips while feeling around a drawer.
Gramercy on this shelf answers it properly: a “rotating blade cylinder [that] switches between cutting styles”, so the edges stay inside the machine.
Ibergrif answers a related problem with a “safety lock to secure the blade during storage and cleaning”.
Mueller’s food container is for the diced vegetables, not the blades. Keep them in the box they came in.
The container and the holder
Free-up countertop space with the Food Container. Which is the chopper’s real advantage: diced onion lands in a lidded box, so you can prep ahead or tip the lot in at once, rather than scraping a board.
Use the Food Holder while cutting small vegetables and fruits. This prevents food from slipping.
A mandoline is the commonest source of serious cuts in a home kitchen, and the injury comes at the last slice. The better answers on this shelf go further than a plain holder: Gramercy puts cut-resistant gloves in the box, OXO Precision makes the holder automatic and height-adjustable and stores it underneath, Joseph Joseph gives three grips for three shapes, Fullstar fits steel tips.
One thousand three hundred and twenty-four grams
The heaviest tool on this shelf. On a mandoline, mass is rigidity — a frame that flexes at the blade mount changes the thickness partway through the stroke.
But Gramercy is the only listing here to publish what the frame is made of: a “substantial stainless steel frame… without wobble or flex”. This page says nothing about its body.
What is not published
No thickness in millimeters, where Benriner publishes a dial from 0.5 to 8 mm, Mueller Austria 1 to 9, Fullstar four clicks and OXO and Ibergrif three each.
No blade grade — “high-qual[ity]”. Only Gramercy (4CR15) and Fullstar (420) publish one.
No dishwasher statement, where four listings here specify top-rack. No slicing surface width. No warranty.
The catalog records the brand as JANSKA while the product is a Mueller — as it does for Mueller’s Vegetable Chopper on this shelf.
