I have a pretty large collection of knives, and recently started picking up a few from this maker. This one in particular (Elf 3.5") has an exceptionally well tuned opening, as in the pressure required is enough to prevent accidental opening but not so much that it is overly stiff. The bias to close is also very tight, and once it is closed it is seated nearly perfected with no outward play. The blade is also perfectly centered on my unit (I'm sure there is variance, but mine was nuts on). It isn't overly heavy, but isn't so light that it would feel cheap or anything. This thing is on par with a few of my favorites from more expensive and established brands.
