Silent locking pocket knives.
-Switch blade knives
-Thumbstud knives

Two sided camouflage clothing.
For example. On one side only full white. And on the other side white and black, and maybe grey in patterns.
-Full white when there is only snow.
-And white and black in patterns for when entering long areas of snow, vegitation and trees for example, maybe.
Tests first.
