Increased Control
The High Recovery Solid XL head uses Key Knife’s innovative Limiter Technology to provide superior cant control through the cutting zone. Key Knife’s Limiter Technology minimizes surging of the cant and step cutting on entry. The use of limiter clamps gives you the flexibility to adjust the limiting surface so that the head continues to perform flawlessly when operating parameters, such as feed speed, are optimized to meet your mills future production needs.

Improved Recovery and Surface Finish
System uses 5 point knife clamping to lock knife edge firmly in place. The Ridge Knife XL System significantly reduces fiber pull and knot-tear, leaving a surface finish second to none. A reduction in fiber pull enables you to decrease your green target, increasing recovery. The innovative Push-Pull feature gives you the flexibility to adjust the placement of each knife edge to meet your exact specification.

Improved Chip Quality
The High Recovery Solid XL System’s innovative clamping system ensures the knife-edge stays firmly in place for a clean and precise cut. A special ridge located on the bottom of the Ridge Knife XL starts the formation of a uniform chip and provides it a smooth transition to the counterknife. The smooth transition minimizes the break up of chips into pins and fines, increasing the production of quality chips.

Increased Operating Efficiency and Safety
The Ridge Knife XL (Extended Life) is the longest lasting indexible knife available. The Ridge Knife XL gives you the flexibility to run longer and produce more quality lumber between knife changes. The unique design of the Ridge Knife XL makes changing knives a quick and safe process. In addition to quick and safe knife changes, the hazardous task of grinding and babbitting is no longer needed.
