Improved Recovery and Surface Finish
Key Knife developed the HY2 to improve the value of your lumber. The HY2 significantly reduces damage to the cant through a consistent tight tolerance cut that minimizes scalloping, fiber pull, and knot tear-out, leaving a surface finish second to none. The HY2’s ability to make a precise and repeatable cut is especially beneficial during the spline making process. You will no longer have to waste valuable time removing a stuck cant due to a poorly cut spline.

Improved Chip Quality
The HY2’s innovative clamping design 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 counter knife. The innovative high capacity counter knife radius reduces pressure off of the chip as it transitions to an expanded gullet. To greatly improve chip flow and chip quality the HY2’s gullet is larger and smoother, minimizing the break up of quality chips into pins and fines.

Increased Operating Efficiency and Safety
The HY2 is 30% stronger than previous High Yield systems. A combination of high quality materials and special surface coatings are utilized to ensure the HY2 is tough enough to handle the most challenging drum style chipping applications. Key Knife’s latest advancement in indexible knife technology, 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. With HY2 you can eliminate the costly and hazardous task of knife grinding and babbitting.
