The key is to maintain the edge angles on the blade. Our knife blades leave the factory with a 30-35 degree inclusive angle. We recommend you use our LifeSharp service. This is a great way to get your knife sharpened, but to also have our qualified technicians service it for optimal performance. Another option may be to contact an authorized Benchmade dealer. Chances are they either offer a sharpening service to their customers or they know of a reputable service in the area.
