About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Package contents of the cutter knife blades

When you pick up the Specht-Tools cutter knives for the first time, you immediately notice the attractive yet simple design. The workmanship of these blades is of a remarkably high standard, which not only ensures excellent stability, but also a long service life. The blades are made of high-quality carbon steel and are therefore extremely robust and resistant.
However, it should be noted that despite the obvious material quality, there is no explicit information on durability. Nevertheless, the Specht Tools brand stands out positively with its successful combination of appearance and workmanship. Unfortunately, there is no information on sustainability.
