Certainly not very sophisticated out-built gentlemen Knife with quite excellent (powder metallurgy) steel blade.
Certainly not superzäh (ie theoretical fragmentation or breakage on the cutting edge), which is likely to be negligible but in the types of use of such a small diameter.
The blade is super sharp and extremely cutting properties. The blade shape is the use of a small diameter very accommodating (eg very suitable to open seams or envelopes) also for cutting along a ruler (similar carpet knife).
Also for the eye and for the material lover was doing something (for steel see the foregoing, also fiberglass handle with slightly transparent version). It is wonderfully light and compact. Doesnt add in the pocket and has a good shape.
