The Bahco sports knives have a durable alumiunium handle, with stainless steel blades and mechanism. The blades lock securely into position when fully unfolded and are only released with the unlock button. This avoids accidental folding. With a small hole on the back end, the knives allow for a safety strap to be attached. This BAHBSTK Twin Blade Sports Knife features two different blades - one standard utility blade and one sports knife blade with serrated edges.
