I too sliced the temp. sheath in the first couple of uses, with the tip poking through about .25 - .5 inches. Had to be very careful of just how far I was shoving it into the sheath, and would certainly not wear this before getting a better sheath for it.
It arrived extremely sharp, and I had no issues with that aspect of the knife.
There is a slight gap between the tang and the black spacer on one side, and the foremost mosaic pin feels a little rough on both sides of the handle, one side in particular feeling more rough.
I like the light feel of the NS against the rather too heavy feel of the WS, but that could just be cos I'm a girl...
Still, the proof of the pudding, as they say, so I'll try both out this weekend and reserve judgement until then.
As for the Puukko being my current fave knife, it's because of it's lightness and versatility. I often forget I'm wearing it on my belt (a problem when you walk into Tescos), and I can use it for every task when I'm out in the woods.
I find the wide blades of the other two knives I've used regularly to be too much for me when performing tasks like feather sticks or carving spoons.
I'm looking forward to trying out both knives and finding their best performance for my own skills and abilities.
