Tim,
On my scale it weighs under 4oz (~3.75) with the blade but without the black foam around the handle. With the black foam it weighs about 4.25.
It does take some fiddling around to assemble it. The first time it took me a while but after doing a few times it becomes a lot easier.
I have a pair of light gloves that I use standalone when the temps aren't too cold and as a liner in heavier gloves or mittens when the temps are colder. I can assemble the saw with the light gloves on.
The one I have is the 15". He also sells a 24".
