A SAK PAK is a Vicotrinox paring knife and a kydex neck sheath (with hole spacing for a small Tek-Lok).
I sharpen and touch up the point on each one of these. They come with a stainless steel ball chain.
These are awesome to throw in a pack as they weigh next to nothing and perform really well. Perfect for picnics, lunches, BUG-OUT bags or to give as a gift. There is really a lot of bang for the buck here.
