A Note on Kydex & Blade Finishes
Kydex is tough, weatherproof, and locks the knife in with a positive click, but it's a rigid material. Under normal use, drawing and re-sheathing The LandShark won't scratch the blade or its coating. However, if even a small amount of grit, sand, or debris gets onto the blade or into the sheath, it can be trapped between the two and leave fine surface marks.
This can happen with any finish, but it's most visible on our glossier finishes (Sapphire Blue PVD, Polished Satin, and Copper Rose PVD), where the smallest marks catch the light. In some cases, these marks can appear the very first time the knife is fitted to its sheath here in our shop, despite the care we take. Keeping the blade wiped down and rinsing out the sheath now and then helps, but with kydex, some minor surface scratching isn't always avoidable.
If preserving a flawless finish matters to you, we recommend the leather sheath, which is much gentler on the blade.
Please note: minor surface scratching from kydex, on any finish and including any that occurs when we first sheath the knife before shipping, is considered normal wear, not a defect. We are not responsible for, and cannot accept returns or exchanges for, finish marks caused by sheath use.

We teamed up with Pro-Tech Knives, building knives in Southern California since 1999, to make the LandShark. Two American makers obsessed with performance.
Hardened to 63–64 HRC using the heat treat protocol developed by Larrin Thomas, who created MagnaCut. Edge retention, toughness and corrosion resistance together, where most steels make you choose two.
Contoured scales stay put in cold, wet and slimy conditions, and a deep finger choil keeps your fingers behind the edge.
