The sheath is "different", but I came around not long after I first got mine. I actually found it to be quite serviceable...expecially after I waded through a stream that was a bit deeper than I originally though. I had the knife attached to my belt when I went almost chest deep into the water.
Had the sheath been made of leather, or even ballistic nylon, I am convinced that the carbon steel blade would have been in pretty deep trouble. I didnt have time to properly dry out the leather, nor was I going to carry the knife out of the sheath since I was in very rough country. The hard sheath is quick to dry and is also very safe.
I in no way consider myself a survivalist or an expert, but its easily the single best knife that I have ever packed with on a hike or camping...and I have some very good knives that cost ten times or more what that little knife costs, custom or otherwise. I cant say enough good thing about this ultra-affordable little jewel of a knife. I hope it works out for you as well as mine has for me.
Now if you want a great yet inexpensive folding knife, I recommend the Opinel folder...
