If you really like the Skinny ASH, then buy one. They're a fine knife -- good slicers, plenty tough for batoning and such.
But you really might want to consider the BWM like others said. It really doesn't weigh that much, and you get a lot of utility for the weight. If you get one now, you can see if you like it. If you don't you can sell it, even as a user for at least the factory cost later.
Big +1 to that. I wouldn't carry an NMFBM, but depending on where I'm going, I'd have no problem hiking with a BWBM. For perspective, according to Hogcult, the skinny ash weighs 414 grams. My .203 thick SJTAC weighs 421 grams, and my bushwacker battle mistress weighs 606 grams. So for a difference of six ounces over the Skinny ASH, you can get a 10.5 inch long blade that will chop, baton, and serve as a machete for brush clearing.
Compared to something like the NMSFNO (593g) or .275 full flat ground FSH (668g), both 8" bladed knives, the BWBM packs a whole lot of utility ino its ~600 grams of weight.
Personally, to me, the broad blade of the skinny ASH doesn't fit what I like in a woods knife, and I'd MUCH rather carry an SJTAC, if I were going for something around the 400 gram mark. I'd be dang tempted to add another 200 grams and get a much more capable blade, though.
Or to really throw a monkey wrench into your plans, the Busse Basic series, and Scrap Yard knives, which have res-c (rubber-like) handles, are significantly lighter than equivalent full tang blades, while still carrying the awesome Busse Family warranty. For example, my SY Son of Dogfather weighs just 445 grams, and carries a 7.5 inch long blade (an inch longer than the skinny ASH), with a more useful blade profile for woods use IMO. Or the amazing Scrap Yard Regulator, which should soon be released, weighed 404 grams in the Test Team version, with a 7.5 inch long blade that is a full third of an inch thick, and is a very capable blade both for woods use and potentially protecting yourself from predators, with its very mean Bowie point.
