This Bahco sports knife has a durable polyamide handle, with stainless steel blades and mechanism. The blade locks securely into position when fully unfolded and is 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, for added safety. The BAHBSLK knife uses utility blades, which can be replaced when blunt.
