Safety knives in Germany: what AI answers say about brands and applications

Data snapshot: 25 September 2026 · Report date: 27 September 2026

At a glance

• In a defined set of 1,501 usable answers, ChatGPT, Google Gemini and Google AI Overviews named MARTOR in 654 answers, or 43.6% of the total.
• WEDO followed with naming in 201 answers, or 13.4%. The gap between first and second was 453 answers, or 30.2 percentage points.
• MARTOR led clearly, but did not appear in 847 of the 1,501 answers. Even the leading brand was absent from more than half of the answers.
• Rates varied by subject: 56.9% for logistics, 33.3% for production and 13.9% for safety and implementation questions.
• These figures describe a one-day, German-language snapshot of 14 tracked brands. They are not market share, demand, revenue or product-quality measures.

What was measured

We tracked 190 German-language questions about safety knives and professional cutting tools. The figures below come from 1,501 usable answers to those questions, collected on 25 September 2026 through ChatGPT, Google Gemini and Google AI Overviews. Empty Google AI Overview results were not counted as answers without a brand mention. The machine-readable dataset, methods and full distribution provides the definitions and underlying figures.

A brand counts for an answer when its name appears at least once in the answer text. The rate is the number of answers naming a brand divided by the same 1,501 usable answers for every brand. An answer can mention more than one brand, so rates need not add up to 100%. Questions covered different buying, use and information situations and were not allocated evenly. This is a bounded sample, not a representative survey of every German search.

The measured ranking

All 14 brands were named at least once. The median was 33 answers, or 2.2%. The table therefore gives the complete distribution for this tracked brand panel, but it is not a complete map of the German market: brands, own-label products and local suppliers may sit outside it.

The gap is not the same as universal presence. MARTOR was named more than three times as often as WEDO, yet appeared in fewer than half of the answers. The stronger conclusion is that the leaders are distinct in this dataset, while even the top brand was absent from most answers. That says nothing by itself about whether an answer suited a particular workplace, covered its task or was technically sufficient.

The subject changes the picture

These groups differ in size and in the questions they represent, so read each rate on its own. The comparatively high figures for logistics and retail fit a question set that includes opening cartons, film, strapping and shipping packs. The lower rate for safety and implementation is not evidence of lower product quality or lower usage. It only shows that the brand appeared less often in the answer text for this particular set of prevention and rollout questions.

Production sits between those points. That is a useful prompt for analysis: a factory should not infer from the overall ranking alone whether answers cover its materials and steps. In food or other sensitive areas, foreign-body controls, cleanability, material and zoning can matter more than a general ranking. Current site requirements and manufacturer documentation remain the basis for those decisions.

Why the material matters more than a generic knife comparison

Selection starts with what is being cut. A carton closure, stretch film and strapping are handled differently and do not necessarily call for the same blade shape or cutting depth. For packaged goods there is another question: how can the pack be opened without scoring the product underneath? A tool that works well on thin film is not automatically suitable for double-wall corrugated board or tight strapping. Conversely, a blade that extends further may offer more reach than a thin retail pack needs.

The DGUV guidance on hand tools starts with the intended use and the material. It identifies risks including slipping, a poor grip, falling knives, exposed blades and unsafe blade changes. For procurement, that means a product sheet should do more than name a knife type. For the actual work station it should help answer: what material is being separated, how is the cut made, how is the blade kept under control, and where is the tool put after the cut?

Those questions sit with different people. Safety staff and supervisors need a selection they can explain and instruction that fits the local procedure. Procurement and engineering need products, blades and spares that can be identified and matched. Workers need a handle and blade action that work with their gloves, posture and the actual package. A short trial with future users may therefore settle more than a comparison by brand or body style alone. Record what was cut and where the tool reached its limit.

The safety feature is also part of the work sequence. Automatic or fully automatic blade retraction, a concealed blade and a fixed cutting depth are different designs, not interchangeable quality grades. Ask which feature supports this cut, what action the operator must take, and how the feature will be checked in daily use. DGUV and trade-association guidance, alongside the manufacturer's instructions, can frame the discussion; they do not replace a site-specific assessment.

Who should be involved in selection?

The ranking describes answers, but a workplace rollout involves more than one person. DGUV hand-tool guidance is directed in part to purchasing staff, trainers, workers and safety representatives. They see different failure points. Procurement can check whether knives, replacement blades and holders are available through the intended purchasing route. Safety staff can check whether selection, instruction and inspection fit the site's risk assessment. Supervisors know which package is handled at each station. Workers can show whether the handle sits securely, whether they can guide the blade as intended, and whether the tool has a proper place after the cut.

A trial should therefore use more than one sample carton. Bring typical packaging from the station, agree the intended cut path and observe whether it opens without unnecessary force. Record whether the blade needs replacing or cleaning and how used blades will be collected safely. If a different hand tool or machine offers a lower-risk way to complete one step, consider that option too. A brand ranking answers none of these site-specific questions.

Sources appearing in the answer data

The domain report records retrievals and citations. A retrieval count is not a quality assessment or recommendation, and its frequency may be affected by the distribution of questions.

The strong presence of occupational-safety sources makes sense: knife selection is about more than brand. It involves fit for task and material, handle, blade travel, replacement and storage. The German Social Accident Insurance (DGUV) advises defining the intended use before selecting hand tools and choosing a tool suited to it. The German Social Accident Insurance Institution for Trade and Goods Logistics (BGHW) offers practical advice for opening cartons and packaging while protecting hands. Neither source is a product approval or a substitute for a workplace risk assessment.

Retrieval and citation events are separate counts from the domain report; they should not be read as shares of the 1,501 answers. A page may be retrieved without appearing as a cited source in the answer, and one domain can occur in multiple records. The distinction is clear for DGUV and BAuA: their pages were frequently in retrieval records, while the dataset logs fewer citation events. That is another reason not to treat a source ranking as a brand ranking or an independent quality check.

Institutional and commercial sources do different jobs. DGUV and BAuA publications help frame selection and prevention. Manufacturer pages are primary sources for designs, instructions, blade compatibility and the applications the supplier describes; they do not independently verify every marketing claim. Specialist suppliers can help make products discoverable and procurable. The curt-tools.com figure should therefore be treated as commercial source presence, not another manufacturer competitor. YouTube can show demonstrations, but a video by itself does not establish approval or suitability at a particular work site.

Purchasing routes also vary. MARTOR links to a dealer locator and describes services for dealers, users and end customers. Moving Edge describes regional sales teams and distribution centres; ECOBRA says on its product pages that commercial resellers can buy directly while commercial end users purchase through trading partners. These manufacturer examples show that different routes exist, not what proportion of sales goes through each. MARTOR appeared in 42 of 85 answers in the dealer-support group, or 49.4%; that denominator applies only to the dealer questions in this sample. Procurement still needs to check the practical details: is the right model available, can replacement blades be matched unambiguously, and can the route supply each site reliably?

Three operating takeaways

1. Structure procurement around the cutting task. Carton board, corrugated board, stretch film, strapping, bagged goods and thin films pose different requirements for blade shape, cutting depth and movement. For each station, list the material, packaging construction, frequency and required cut depth. Then choose a suitable tool and check whether a safety knife can do the job reliably.

2. Introduce the tool and the safety routine together. A knife with automatic blade retraction does not solve every workplace issue by itself. Workers need to know its intended use, how to check the blade, how replacement works and where the knife goes after use. Test handling with the actual operators and materials on site; document the decision, instruction and checks under your workplace procedures.

3. Treat food and sensitive zones as a control system. Detectability, colour, cleaning method, replacement inventory and breakage checks depend on the site. A manufacturer's detectability claim does not replace testing with your own metal detector or X-ray system. Before buying, define how knives are issued, counted, cleaned, inspected and removed from the process when damaged.

Limits of this snapshot

The analysis answers a narrow question: how often did the recorded AI answers name one of 14 selected brands across a defined set of German-language questions checked on 25 September 2026? It also shows that mention rates varied among the subject groups in this dataset. The complete dataset records all brand values and segment denominators.

It does not show the whole market, actual sales, market shares, employee awareness, user satisfaction or product safety. It establishes neither additional revenue nor a causal effect from a website or individual content. The questions were an editorially defined selection, not a random sample; their unequal distribution shapes the overall rate. Answers can name multiple brands and may contain general or incomplete recommendations. Models, search surfaces and their sources can also change over time. This is a one-day snapshot, not a monthly movement or trend line. The ranking combines three different answer systems. An aggregate can hide differences between them; it should not be read as saying which individual system names a brand more often. That would require separate, sufficiently large analyses for each surface.

For a real purchasing decision, do not use the overall ranking as a shopping list. Check the relevant use group, read the specific answer and its sources, compare it with manufacturer and occupational-safety information, and test the tool under your own conditions.
