I will be getting my BK2 in the mail today and will be ordering a new sheath for it. I have found a couple leather sheath that are made for them that have a fire steel holder on them that I really like. My question is for you guys that have leather sheaths, do you keep your knife in the sheath when you are not using it. Sounds like a crazy question. I have been told that leather sheaths gather moisture from the air and can make your blade rust. By the way this is a great forum here. I have been a knife nut ever since my dad let me buy my first little pocket knife for $3.14 at the local farm and home store when I was seven.
