I believe at least Brisa sells Yakut blades. Lamnia.com
might have them too, but I'm not sure about that.>>1313521
I live walking distance away from their store (though at the moment in off-grid cabin in Lapland), but only bought one Jääkäripuukko 140 few weeks ago. Didn't buy the sheath for it even though they had some in the store, I carved one out of wood, but it still needs a belt loop of some sort. Waiting to see how their kydex sheath comes out, should be next year.
I decided to get the Jääkäripuukko to try it out and because it really is good value for what it is. I even asked to check out a few of them and pick a good one, but to be honest the quality was very consistent, grinds and plunges were even and tips were mostly symmetrical, common problems with scandi ground blades. Not a bad knife, though my hand did get a bit sweaty using the rubber handle when doing extended carving for the sheath. My main knife for the past few years has been EnZo Camper, I will keep using it in the future too, but the Jääkäripuukko seems like better value to me.
