Great ideas.
I may end up buying more than one item.

Guess what I have found yesterday in a garage sale !

Its a FIXED knife with
a FULL straight edge,
FULL serrated edge, and
a FULL length saw !
Plus mini pry bar, and can opener ..etc.

Now did I count things correctly ?
Three full lengths of blades in one fixed knife ?
Yes.

It looks like any fixed knife (4-5 inches) with a handle. The handle splits in two halves and they rotate 180 degrees to cover either the tang or fixed blade.

The tang is not the normal rectangular piece of metal found in other knives. Rather, it is a blade with one side serrated and the other has saw teeth. The tip is pry-bar-shaped with a can opener on the side.

So, you rotate the handle twin halves and they cover the knife blade. Then what you get is a "tool" that doesnt look much like a knife but a straight one-piece "multi-tool". When you rotate the half handles back to cover the multi-tool, this thing becomes just like any other fixed blade knife.

I'll try to post a picture.

Its made of stanless steel. And only says (Stainless - USA) Nothing else. I am not worried much about losing the edge and how hard it is to sharpen, since I will only use it occasionally and save it for a last resort asset in the BOB.

The handle is OK, but I'll try to find some sort of sleeve to contain its two halves ( they have a lock to keep them together, but still). Also, I have to find a sheath for this thing.

Having found this thing does NOT mean I have stopped searching.
I'll still appreciate more suggestions. I really really liked a number of them especially the ones with "non-knife" concept.

Thank you again folks.
