NTK05

Good Quality

It's even smaller than expected, and since it is made of Titanium so you cannot tell if there's something in your hand because it's so light (understatement, it's tiny, smaller than my keys (a good thing)). It has a great build quality overall and a satisfying click when you seathe the blade. The only negative points I have would be that the blade (a Scalpel No. 11 blade) as well as the part that connects the blade to the knife handle have some wiggle room making those parts feel a bit flimsy. Aesthetically very pleasing, would have hoped for a more polished surface on the blade handle (marks from the machining process still visible).
The company states that the scalpel blade is replaceable but there's no instruction on how to do so on the packaging and I still don't know how to remove the blade.
Overall a very nice addition to my keychain I can recommend buying it, but 35€ is a bit too much I would feel better with purchasing this for maybe 15-25€.
