How do self-sharpening knives work?
The knife block contains sharpening elements, in many models made of ceramic. When you slide a knife into the block or pull it out, the slot guides the blade past these elements and sharpens it slightly. So it is not classic sharpening with a whetstone but a small touch-up each time you use it. More details can be found in the respective manufacturer's description.
Are self-sharpening knife blocks any good? Pros and cons
Pros
- Convenient: the knives are kept in shape almost in passing in everyday use.
- Little effort: you need no whetstone and no practice.
- Everything in one place: knives and scissors are sorted and within reach.
- Good for beginners: anyone with little time for maintenance gets a simple solution.
Cons
- Fixed sharpening angle: you cannot choose the angle yourself.
- No substitute for proper sharpening: heavily worn or damaged blades usually do not become like new. After longer use, proper sharpening can still make sense.
- Material removal: each sharpening removes a little material, so the blade wears down over the years.
- Space requirement: the block stands on the worktop.
- Only for matching knives: the block is designed for the knives supplied with it.
Who is a self-sharpening knife block worth it for?
| Type | Worth it? | Why |
|---|---|---|
| Anyone with little time for maintenance | Yes | The knives stay in shape without extra effort. |
| Anyone setting up their first kitchen | Yes | A complete set from one source, for example as a housewarming gift. |
| Anyone who enjoys working with a whetstone | Rather not | The fixed angle leaves less room for control. |
| Anyone with little worktop space | Depends on space | The block needs surface area. |
| Anyone who owns very high-quality single knives | Rather not | The block is meant for the supplied set. |
Is a knife block unhygienic?
A knife block is not unhygienic in itself, but moisture and crumbs can collect in the slots. So: dry knives thoroughly before putting them in, and clean the block now and then according to the manufacturer's instructions. Check the manual to see whether and how the block can be emptied or wiped out.
Zwilling or WMF: which is better?
Both are well-known German brands, and there is no blanket answer of "better". What matters are the features, blade steel, handle and price of the individual set. It is best to compare the manufacturer's details: which knives are included, what the blades are made of, whether scissors are included, and whether the block fits on your worktop. We have the ZWILLING Gourmet knife block in the shop and can therefore only give concrete details on that; we do not carry out our own comparison with WMF knife blocks.
Our recommendation: ZWILLING Gourmet knife block
The ZWILLING Gourmet SharpBlock is a 7-piece set with block. According to the manufacturer it contains: a paring and garnishing knife (10 cm), a utility knife (13 cm), a meat knife (16 cm), a chef's knife and a bread knife (20 cm) and multi-purpose scissors. The knives are sharpened as they are pulled out by integrated ceramic sharpening stones; according to the manufacturer the blades are ice-hardened and made of stainless steel. The handles are ergonomic and the scissors suit right- and left-handed users. According to the manufacturer the set is made in Solingen.
Our assessment: It suits anyone who likes cooking and wants a complete set from one source – for example as a housewarming gift. The self-sharpening function keeps the knives in shape day to day; proper sharpening after longer use can still make sense.
Care tips for knives in the block
- Wash by hand and dry if the manufacturer recommends it. Check the details for your model.
- Only cut on suitable surfaces, such as wood or plastic, not on stone or glass.
- Do not put knives loose in the drawer so that the edge is not damaged.
- Keep the block clean: wipe it out now and then according to the manufacturer's instructions.
