The SXS is a “small” version of the SXB meant to complement it while out in the field. Small to EJ, and when compared with the SXB, but most will consider this a mid-sized knife. The basic blade shape has remained the same, but the handle has been modified to accommodate some different usage options. There are holes in the handle front and back to provide lanyard and lashing options. The sheath is Kydex with beta loops designed to give the user multiple mounting options, such as scout style, appendix, horizontal, IWB, on a pack, on a vest, etc. Just remove the screws once the snap is open and reposition the straps however you would you prefer to carry it.
