Edging
Edging the blade with Buck's Edge2x™ Technology.For 35 years, Buck Knives followed a blade-edging protocol that produced blades with excellent edge-holding qualities. In 1999, Buck decided to edge out the competition with the most exciting innovation in edge technology-Edge2x.Chuck Buck, along with Buck engineers, quality and production supervisors, and experienced blade edgers, experimented with angles and materials before coming up with the exact edge geometry specification to create this new, thinner, sharper edge. This edge was achieved by changing the included angle (the total of the angles on both sides of the blade) from a range of 35° to 50° to a range of 26° to 32°. This range allows Buck greater flexibility to match the angle of the blade to the function of the knife. The initial part of creating the edge is performed during step #7, hollow grinding, which is a computer controlled, automated machine process. During this grinding process, blades are tapered to a specific profile. This yields a consistent blade thickness at the edge that cannot be duplicated by hand. Then the human hand takes over on an edging wheel. Another key to the success of the Edge2x process is that we converted to using laminated leather stropping wheels instead of stitched cloth. The sturdiness of the leather wheels enables us to eliminate "rollover" (where the edge can lose its ideal keenness) and create razor-sharp blades with consistency.The human touch lessens the risk of burning, which can lower the hardness of the steel. Experienced edgers, who have been with Buck for many years, went through extensive training to learn the new system. It took many months for them to perfect the process, but it has been well worth the effort.A computerized test for edge retention, developed by CATRA (Cutlery and Allied Trades Research Association), is performed on blades for each knife model. For inspection, a laser-measuring device, called a goniometer, is used to check the precise angle measurements to verify that the edge matches specifications. Edge2x blades have been compared against our older Buck blades and evaluated using the CATRA tests, which proved the superiority of our new edging process. With Edge2x Technology, every knife made by Buck is sharper out of the box, holds an edge much longer and is easier to re-sharpen when needed. " |
