Sharpening

Professional sharpening solutions for intensive use: X-Fil crossed-rod sharpeners and honing steels. Edge maintenance during production through regular edge realignment, supporting cutting performance, safety and consistency in the agri-food industry.

Crossed-rod sharpeners

Guided crossed-rod sharpeners: standardized motion, consistent results, all-stainless equipment compatible with IAA environments, for tabletop or workstation use.

During production, the cutting edge gradually deforms under mechanical stress. Sharpening makes it possible to realign the edge and maintain a functional cut without unnecessary material removal.

X-Fil crossed-rod sharpeners

X-Fil sharpeners are designed for simple and regular use in professional environments. They can be used on a table with a stand or fixed directly to the workstation. The crossed-rod system guides the blade during sharpening, reducing variations caused by differences in operator technique.

Design and materials

  • Frame: stainless steel compliant with EN 10088-1 / 1.4307
  • Rods: martensitic stainless steel compliant with EN 10088-1 / 1.4034
  • Stops: thermoplastic elastomer (TPE), heavy-duty grade
  • Return system: martensitic stainless steel compliant with EN 10088-3 / 1.4310

Why maintain the edge regularly

It is preferable not to wait until cutting performance is lost. Implementing a sharpening frequency adapted to the product being processed helps maintain consistent cutting performance and extend knife service life.

Operating principles (reminder)

  • Tool designed for regular and standardized use in production.
  • Motion must be visually controlled to avoid damage and preserve the edge.
  • Do not strike the edge against the rods.

Recommendations — X-Fil X1

  • Mainly use the upper area of the sharpener.
  • Keep the blade perpendicular to the rods.
  • During use: 1 to 2 regular passes as needed.
  • Locally damaged edge: work only on the affected area with visual control.

Never do — X-Fil X1

  • Do not systematically use the lower area.
  • Do not use the lower area on a freshly sharpened knife.
  • Do not use the sharpener without watching the motion (risk of catching the frame and creating a notch).

Recommendations — X-Fil X2 and X21

  • Present the blade straight, facing the rods.
  • Sharpen from the base of the handle to the tip in one continuous motion.
  • Knife in use: 1 to 3 passes at mid-rod height, final pass without rod movement.
  • Worn edge: 1 pass at the bottom of the rods without pressure, then 3 passes at mid-height.

Never do — X-Fil X2 / X21

  • Do not strike the rods.
  • Do not automatically go to the bottom of the rods at each sharpening.

Cutting performance and edge retention (internal references)

X-Fil X1, X2 and X21 sharpeners restore cutting performance in approximately 95% of cases. By comparison, an excellent operator using a honing steel under production constraints generally achieves between 50% and 70%.

Another advantage of X-Fil sharpeners is edge retention, reported as 3 to 6 times higher than with other sharpening tools. These results can be supported by measurement data; the validation tool used is the Mentor.

Honing steels

Honing steels for trained operators: manual edge maintenance during production, a flexible and immediate solution at the workstation.

Dassaud Fils also offers honing steels designed for intensive professional use. They are intended for operators skilled in manual honing and looking for a flexible tool to maintain the edge in functional condition during production.

Characteristics (depending on model)

  • Material: stainless steel
  • Handle: thermoplastic elastomer (TPE)
  • Coating: hard chrome, thickness 15 to 20 microns
  • Hardness after heat treatment: 65 HRC
  • Handle operating temperature: −30 °C to +100 °C
