I use a KK 6 ft light blade for snow. Its just fine for that. I also use it for dirt, and as long as you dont hit a big root or BFR it will scrape some dirt.
BTW, if you do hit a big root or BFR, or as in my case a old logging cable, its around 45 bucks to get it rewelded /forums/images/graemlins/tongue.gif
