there is no definitive answer to which folding knife brand consistently provides the absolute best factory edge. Different knife brands have different manufacturing processes, quality control standards, and edge profiles for their blades. Additionally, the "best" factory edge can be subjective and depend on individual preferences and needs.
That said, several knife brands are well-known for their high-quality factory edges and overall craftsmanship. Some of these brands include:
Spyderco: Spyderco is renowned for producing knives with excellent factory edges. They often use premium materials and have precise grinding techniques, resulting in sharp and reliable blades.
Benchmade: Benchmade is another well-respected brand known for its precision manufacturing and high-quality factory edges. They use a variety of premium steels and maintain strict quality control standards.
Zero Tolerance (ZT): ZT knives are known for their robust build and attention to detail. They typically have impressive factory edges, especially for tactical and EDC (Everyday Carry) models.
Chris Reeve Knives (CRK): CRK knives are known for their exceptional craftsmanship and attention to detail. They use high-quality materials and maintain precise edge geometries, resulting in sharp and reliable knives.
Kershaw: Kershaw offers a wide range of knives, and many of their models come with impressive factory edges at budget-friendly price points.
Cold Steel: Cold Steel often provides factory edges that are exceptionally sharp, especially on their tactical and outdoor-oriented knives.
Remember that even with high-quality factory edges, the sharpness and longevity of the edge will eventually depend on how you use and maintain the knife. Regular sharpening and proper care are essential to maintaining the best performance from any folding knife, regardless of the brand or initial factory edge.
