A precision-machined aluminum fixture designed to improve access to the test media when measuring knives with bolsters, wide blades, and complex blade geometries.

Accessibility
The specialized open construction provides improved access to the test media, allowing the cutting edge to approach the testing point with fewer obstructions.
Blade compatibility
The fixture is especially useful for knives with bolsters, wide blades, unusual profiles, and other blade geometries that may be difficult to position with a standard fixture.
Construction
The rigid aluminum body securely holds the test media and provides the stability required for accurate, consistent, and repeatable sharpness measurements.
Specialized design
Standard test fixtures may restrict access when testing blades with a large bolster, considerable blade width, or an unusual edge profile.
The Competition Aluminum Test Fixture provides more open space around the test medium, making it easier to correctly position these blade types during testing.

Test media
The fixture is designed to securely hold DoubleX+ Test Media used for BESS sharpness measurements. Test media is sold separately.

How to use
Place a piece of DoubleX+ Test Media into the fixture according to the manufacturer's instructions.
Position the Competition Aluminum Test Fixture on the compatible Edge-On-Up PT50 Series sharpness tester.
Align the section of the cutting edge being tested directly above the test medium without applying lateral pressure.
Apply controlled downward pressure until the test medium is cut and record the displayed BESS result.
Replace the test medium when it becomes worn or damaged to maintain accurate and consistent measurements.
