These Side Cutters are designed specifically to cut single strand fishing wire. Not only are these Stainless Steel but we have brased a Tungsten Carbide insert in both the upper and lower jaw. Are you tired of seeing these removable insert type tools breaking twisting, screw deforming? Well that is exactly why we opted for a fixed cutting edge. If you are looking for Side Cutters that provide both corrosion resistance and an ergonomic handle, this may just be the tool to try. Toit Side Cutters work perfectly alongside our Haywire Twist Tool to create a Haywire Twist, Tokyo Rig or even a Dingle Dangle Rig.
