Blade and locking are sluggish, the advantage of this is that the blade so stuck like a knife with a fixed blade. The cutting I had to re-grinding with my Naßschleifstein because I anzeigten blunt points in plan view and reflections of the paper-cut test was negative. Most disappointed I was, but not quite on the hinged blade thereby wegstand at an obtuse angle and not in a straight line to the handle. That reminds me of the seller at a mail did not answer whether he exchanges me the knife, I decided the misalignment of the blade itself correct. With a Dremel I fäste a small groove in the book where the blade strikes and now the knife goes on and thus perfectly. The next thing I do is to install a small fire steel by means of a hole in the wooden handle, as I have seen it on YouTube. I have therefore the Opinel Carbon appointed as only one blade of carbon-steel can be used as a scraper for the fire crew. The Opinel blade back is sharp and therefore suited best to make sparks. Conclusion: A super knife which is unfortunately sometimes delivered not quite perfect. Nevertheless buy recommendation!
