Utility Knife Blade Test | Bosch, Wisent, Topmaster & Color Expert Compared

In this video I compare five utility knife blades using objective BESS sharpness measurements before and after testing. The blades tested are: • Bosch Professional • Bosch Green • Topmaster • Wisent • Color Expert Each blade was tested using the same procedure and the same test rig. The cutting sequence included: ✔ Corrugated cardboard ✔ Drywall ✔ Copper pipe ✔ Steel staple strips All blades were tested under identical conditions and their sharpness was measured before and after the test using a BESS sharpness tester. The goal of this video is not to declare a universal winner, but to show how these blades performed under the specific conditions used in this test. Important Notice All products were purchased independently. This video is not sponsored by any manufacturer or distributor. Results apply only to the samples tested and to the methodology used in this video. Different materials, working conditions, production batches, or testing methods may produce different results. If you enjoy independent tool testing, let me know in the comments which blades or tools you would like to see tested next. #UtilityKnife #BladeTest #BESS #ToolTest #HandTools #Bosch #Topmaster #Wisent #ColorExpert #DIY #ConstructionTools #ToolReview
