Designed by custom knife maker Ken Onion the Boa 1580 is another Kershaw masterpiece. The first thing that stands out is the elegant design of the knife. The Boa simply looks great. It features a stainless steel recurve blade with Tungsten DLC coating. This DLC (diamond-like carbon) coating is a thin hard protective shell that is scratch resistant and helps to give the Boa its smart crafty look.

The blade material is a high-end stainless steel: the S30V. This steel has good edge retention and it is sharp out of the box. Without doubt, the Boa is a great utility knife with a fine cutting ability, however it could be a little difficult to sharpen, especially if we consider the geometry of the blade.

The handle not only looks good but is quite comfortable in your hand. The design and material (061-T6 anodized aluminum) contribute to provide a secure grip.

One of the highlights of Kershaw knives is the SpeedSafe assisted opening mechanism. A torsion bar helps to keep the blade closed preventing that it opens by accident, and at the same time allows a fast deploying with only one hand. In the Boa the thumb stud that commands the SpeedSafe device can be placed either the left or right side of the blade for an ambidextrous opening.

In addition, the Boa comes with a pocket clip to secure it to your pants and a locking liner to lock the blade into position after the blade is deployed.
