Adjustable Bread Slicer: Thickness Ranges in Inches and Millimeters Compared

What “adjustable” means on a bread slicer

Almost every manual bread slicer is sold as “adjustable”. Behind the word sit three different mechanisms:

• Stepless fence (crank slicers). A knob moves the stop plate closer to or farther from the round blade. Any setting between the minimum and maximum is possible. The Zassenhaus Classic, Graef H9 and ritter manus 3 work this way.
• Fixed steps (slicing guides). The frame has slots or a setting board for a few thicknesses. The Akebono PS-955 has five: 10, 15, 20, 25 and 30 mm.
• Adjustable width. Many plastic guides adjust only to the width of the loaf, not to the slice thickness. A listing that says “adjustable” may mean this.

So the first question for any listing is: adjustable in what, and from how thin to how thick?

Our pick: Zassenhaus Classic

Our pick: hand-crank slicerZassenhaus

Zassenhaus Classic

The classic rotary bread slicer: serrated Solingen blade, crank, beechwood base – no motor, no cord.

Why here: Stepless from 1 to 18 mm (about 1/25 to 0.7 inch) – thin sandwich slices and thick toast from one documented knob.

Best for: Households that mostly slice bread and want a brand crank slicer with documented specs and a compact footprint.

Strengths

• Stepless 1–18 mm (about 1/25–0.7 in) – from thin sandwich slices to thick toast
• Die-cast and stainless steel body on a beechwood base, four suction feet
• Smallest footprint of the brand hand-crank slicers in our comparison

Weaknesses

• No carriage and no end-piece holder listed – the last piece of the loaf needs care
• Premium price class, several times the unbranded crank slicers
• Only the blade is documented as made in Solingen; retailers list the Czech Republic as country of origin

According to the retailer Culinaris, the Classic adjusts steplessly from 1 to 18 mm. That covers very thin slices for sandwiches and slices thick enough for toast. The range is published, not estimated, which is why it is our pick on this page. Its limits: no carriage and no end-piece holder listed, and the premium price class. Full details are on the Zassenhaus Classic page.

Thickness ranges side by side

Two patterns stand out. First, no documented slicer with its own blade goes beyond about 0.8 inch; the wider ranges come from seller listings. Second, the guide reaches the thickest slice but starts where the crank slicers are already mid-range. The question of which thickness suits sandwich bread, toast or sourdough is covered on bread slice thickness.

The models in detail

Zassenhaus Classic: 1 to 18 mm

The Classic covers the most ground at the thin end among the bread-only crank slicers: 1 mm is thinner than any guide reaches. Its upper limit of 18 mm is about 0.7 inch – enough for thick toast, but not for French-toast slabs of an inch. The manual names an adjustment knob and a stop plate; there are no printed steps in the data we read, so you set the thickness by eye or with a test slice.

Graef H9: 0 to 15 mm with a dial

Graef sets the H9 steplessly from 0 to 15 mm via a dial on the fence. The range is the narrowest of the three brand crank slicers at the top end, but it starts at zero, which suits cured sausage and cheese as well as thin bread. The carriage with thumb guard and the end-piece holder in the box make thin slices easier to handle safely.

Our pick: bread, cheese & cured meatGraef

Graef H9

All-metal hand-crank slicer with a stainless carriage, thumb guard and end-piece holder.

Why here: Stepless from 0 to 15 mm with a dial on the fence, plus carriage, thumb guard and end-piece holder for thin slices.

Best for: Kitchens that slice bread and also firm cheese or cured sausage without electricity.

Strengths

• Removable stainless carriage with thumb guard, end-piece holder included
• 7.5-inch (190 mm) serrated stainless blade, slice length 150 mm (about 5.9 in)
• Made at the Graef plant in Arnsberg, Germany, according to the manufacturer

Weaknesses

• Large footprint: 14.8 × 14.4 in (375 × 365 mm)
• Slices only up to 15 mm (0.6 in) – no thick toast slices
• Premium price class

ritter manus 3: up to about 20 mm

ritterwerk describes the manus 3 as adjustable from wafer-thin to about 20 mm (0.8 inch). That is the thickest stepless setting among the documented crank slicers. The trade-offs: 7.3 lb, a large footprint and an end-piece holder sold separately.

Budget crank slicers: ranges you cannot check

The Brvclon listings name a thickness scale and a range of 0 to 0.9 inch (about 23 mm); other unbranded crank slicers say only “adjustable thickness”. None of these comes with a data sheet we could read, so the upper limit is a seller claim. They sit in the budget to mid-range price class.

Guides: fixed steps for your own knife

The Akebono PS-955 is the only guide here with documented steps. Globalkitchen Japan lists 10, 15, 20, 25 and 30 mm and translates them into slice counts for a Japanese sandwich loaf (shokupan): 12 slices at 10 mm, 8 at 15 mm, 6 at 20 mm, 5 at 25 mm and 4 at 30 mm. The retailer calls it a horizontal slicing design. The Kiss Core guide adjusts width and thickness, but its listing does not name the steps.

What to check before you buy

1. Thinnest and thickest setting in numbers. “Adjustable” alone tells you nothing. Look for a range in millimeters or inches.
2. Stepless or steps. Stepless for in-between settings; steps for repeatable results.
3. Where the number comes from. A spec sheet from the maker or a retailer with technical data beats a listing title.
4. Loaf size. A wide range does not help if your loaf does not fit. Only the Akebono states its loaf limit (about 7.9 × 5.5 inches); see sourdough slicers for wide boules.
5. Electric is not thicker. Home food slicers such as the Cuisinart FS-75 stop at 1/2 inch; more on the page about electric bread slicers.

Typical mistakes

• Reading “adjustable width” as “adjustable thickness”. Many guides only adjust to the loaf.
• Expecting thin slices from a guide. Guides start around 10 mm. For very thin slices, a crank slicer is the tool.
• Taking the seller's maximum at face value. The 0.9-inch claims are not backed by a data sheet in our sources.

Find your slicer

Our recommendation

If you want one slicer for thin and thick slices of bread, take the Zassenhaus Classic: 1 to 18 mm, documented and stepless. If you also slice cold cuts, the Graef H9 with its 0 to 15 mm dial and carriage fits better. If thick slices matter most and your loaf is a pan loaf, a guide like the Akebono PS-955 reaches 30 mm with your own knife. The mechanism behind the knob is explained on the hand-crank bread slicer page, guides on bread slicing guides, and all models in our comparison of manual bread slicers.
