I just picked up the Gerber Bear Grylls ultimate knife yesterday it's pretty cool with all the features it comes with.
pummel on the base of the handle.
emergency whistle on the lanyard.
nice rubber grip.
partially serrated blade.
fire steel.
sharpening stone.
sheath with multiple carry options.
mini survival guide and emergency signal guide.
rubberized sheath with a friction fit clamp in case you forget to secure it.
Has three holes in the handle for tying it to a stick/limb for a spear.
