There are several features that hunters can have built into a custom hunting knife. A hunting knife that is well balanced and fits the hunter's hand comfortably is an advantage on any hunt. Custom hunting knives often have the top edge of the blade sharpened to aid a stabbing movement. A hollow-ground cutting edge keeps its blade longer. A finger lug keeps your hand from slipping forward when stabbing, and provides a good grip. Custom hunting knives can be made with thicker blades and stronger metals than normal hunting knives. A good custom hunting knife can chop oak and still be used to shave with. Look for a reputable dealer who specializes in crafting hunting knives.
