Cons: None
Very sturdy, no nonsense hard use knife
The knife arrived so quickly. Great shipping service ! The knife was perfect , no issues with quality, fit, or finish. But, the knife was much larger than I expected. This is not a small or light knife. You definitely know when it's in your pocket. This will be a work knife. I may order the smaller, non locking blade for casual carry.

Pros: Overall Quality
Cons: Lock Ease of Use
Glad to have it
As far as I can tell, every part of the knife: rivets, locking mechanism, lanyard loop etc. are stainless. Should last pretty much forever. Very slim in the pocket, blade lockup is very solid with no looseness. Blade shape is surprisingly useful. Aesthetics are great. Otter stamp is cool and nice brushed finish. OK it’s a $35 knife. Mine came in a plastic sleeve all dirty and covered with machine oil. Edge was rough. But cleaned up easily and I always put a new edge (or at least refine the existing edges) on a knife anyway. The steel is “Solingen” which is undoubtedly some variant of German 0.5 carbon stainless, but the heat treat is pretty good. You won’t be disappointed with the edge holding, unless you are expecting something like S 30V. All and all a very cool knife. One possible downside is that the lock spring is pretty stiff. If you have small hands you might have trouble with it.

Cons: None
German quality
I will be buying another. Top quality German made to perfection. It will survive a nuclear war. Very utilitarian, but hey it is a tool, right? If you want something to look at, get something else, but I you need a real man's knife, you found it. Quit reading this an buy one for yourself. You will not regret it.
