I have some SOG stuff from many years ago -- first rate. But I suspect they're feeling the heat these days, and perhaps they're looking for the mass market at the lower price point? Just my impression, I may be totally wrong (and I hope that's the case).
I haven't seen or used the gear in this woot deal. The entrenching tool has extremely grumpy/negative reviews from Amazon buyers. The hatchet is supposedly 420 steel -- I worry about stainless in an axe or machete, since it's more prone to chipping/fracturing than straight carbon.
So you pays your money and you takes your chances. My $0.02.
