Benchmade takes tried and true designs of the past and pushes them to another level of quality yet again with the American-made 581BK Black Blade AXIS-Lock Folding Knife. This assisted-opening folding knife is designed by expert designer and knifemaker Warren Osborne, and is a sturdy piece of machinery from Benchmade's 'Blue Class' product line that further demonstrates their commitment to excellence in all that they endeavor to achieve. If you're looking for a solid upgrade for your current folding knife, the 581BK is a good place to begin your search.
Like its cousin, the 581 Barrage, the 581BK has a 3.6" M390 Super Steel blade that is sure to last through all challenges. Where this knife differs from the 581 Barrage is in the handle. The 581BK's handle is constructed from the tough fiberglass compound G10 in addition to the tough aluminum bolster. This means that the 581BK's handle is built for both performance through repeated use as well as comfort and easy handling.
Measuring in at 4.75" and 5.2 oz., the 581BK is the perfect size for a versatile folding knife and is an ideal everyday carry. This assisted-opening knife utilizes Benchmade's ambidextrous AXIS-Lock technology to ensure that you'll experience unparalleled levels of ease when handling your 581BK in either hand, and the tip-up pocket clip means it can be stored easily and discretely at waist level so it is never out of reach. Benchmade's legacy of excellence continues at full speed with the 581BK. If you are in the market for a medium-sized folding knife, it's hard to go wrong with Benchmade's 581BK.
