I have found it. It is lightweight. When you wear it as it was made to wear you can get to it easily without reaching into your pack. It will do all the jobs I could conceive of in a normal hike: cut food, cut rope, cut cheese, etc. It is the Buck Hartsook Neck Knife. I came across it accidently and it is a little humdinger. I have carried larger knives many times but have read many posts where posters talk about that is another area we can cut down on the weight we are carrying. Then they describe just what do we really, really use these knives, dream knives, rambo knives, multi-tool knives, etc., for? NOT MUCH! I know there are exceptions to this. I have come to a place where I had to agree. So I have been looking for a light knife. I think this is it. Look it up at buckknives.com and look for the Hartsook knife. You can also see this little knife in action on YouTube.
