Sharpening a HollowFlat Blade using external sharpener. Sharpened on the flat side only, as shown in the photo, the HollowFlat™ Blade is placed with the flat side of the blade in contact with the sharpening surface. The design of the HollowFlat™ Blade features an integral guide that ensures the 0° (zero degree) angle of the bevel is maintained during the sharpening process for perfect results every time. Just knock off the burr when you're done <see more on sharpening basics>.

The HollowFlat™ Blade is a Miltner Adams innovation featured exclusively in Miltner Adams knife designs.

HollowFlat Blade The HollowFlat™ Blade is similar to a chisel grind blade, with the exception that the flat side is hollow ground, producing a raised flat bevel that makes it possible to sharpen on the flat side. In addition, the shape of the hollow grind creates a spacer opposite the raised flat bevel that acts as a built-in "guide." The HollowFlat™ Blade is sharpened on the flat side only.

Examples of double bevel and chisel grind blades:
