Frequently Asked Questions
What's the difference between this OTF knife and a folding knife?
An out-the-front (OTF) knife deploys the blade along the length of the handle rather than pivoting open. That means it opens and closes with one hand and one motion—no two-handed operation needed. It's faster to deploy but requires different carry and handling practices than a folding knife.
Is D2 steel easy to maintain?
D2 is a tool steel that holds an edge well and resists corrosion better than basic stainless steels, but it's not stainless. It can develop light surface rust if exposed to moisture for extended periods without care. Regular wiping and occasional light oiling will keep it in good shape. The stonewashed finish actually helps hide minor blemishes and patina.

Is the FS-X Gen III Medium a good size for everyday carry?
At 3 inches of blade and 4.68 inches of handle, the FS-X Gen III Medium is a practical middle ground—compact enough for EDC but with enough blade and grip for serious work. Check your local knife laws before carrying any blade, as OTF knife regulations vary by jurisdiction.
