I've got a thought- does anyone know of a saw, built like a fixed blade knife, say 7-8" long? It isn't super long, but for stuff up to 4" it should work fairly well.

I've got an OK sheath that has been empty, I just don't like how my Mk IIs fit in it. I've got a lot of good sheaths for my Ka-bars, and I'm leaning towards smaller knives right know actually. I'm thinking that with a SAK or multi and a ferro rod on one hip, a Mora on my neck or other hip with a lighter and small flashlight, and a PSK, I've got most of the tools covered. Sling a water bottle and wrap a poncho around the strap, and I'm off for the day if I'm going ultalight.

Have you looked at the Stanley FatMAx drywall-type saw? It has a pretty aggressive tooth pattern on it.

Wood will dull this and almost any drywall saw relatively fast. If you go this route, look to the Milwaukee brand. The handle has the same blade connector as their Sawzall product. That enables you to remove blades for easier storage, not to mention replace broken blades.

I tried to find it on their website, and can't. It may have been discontinued.

Stanley says the saw is good for wood, plastic and drywall. Just looked at it on their site. Just clearing up any confusion, if any, about the saw.

Good idea about the Milwaukee.

I've tried Stanley dry wall saws. Good on kiln dried pine, not so much on green wood, and lousy on hardwood.

What I'm thinking of would look like a small cross cut saw, square tipped and about an inch and a quarter wide, but with a handle like a keyhole saw. Basically the love child of a keyhole saw and a laplander. Stanley makes a keyhole with a d-gaurd type grip, but it is is very skinny and flexible- I want a beefy one. :P

“Pole saw” with a shorty pole on it?

That isn't the worst idea... They use a standard mop handle thread, don't they?

Either that, or they use a common type of garden tool handle (shovel, etc.) for which short ones are pretty common. (Or you could just cut the supplied handle to the length you want, I suppose.)

I posted this photo a week or so ago.
In my case I used a folding type of handle but they make all sorts of handles to take Sawzall blades you can find both the blades and handles at home depot

How about the SOG Revolver. It is almost a "fixed blade". It does not quite meet the description of what you are looking for though as it has a traditional handle unlike a keyhole saw.
