Hello Giovanni!
Nice to meet you here! It is great to see that one really cares about the opinion(s) of the end user

.
I hope my english is sufficient to express my thoughts.
As obvious, the customer opinions here in "old europe

" are as different as the ones in the States. It's a tough job to design a knive aimed at the german market.
To the question, what is typically German:
efficiency and reliabillity.
So, for a "German" knive, i think it would have to be a hard use gear - tool with the simple elegance, that comes from an efficient design. It should be strong, but not bulky. Therefore only High end materials should be used. This also makes the knive light and therefore a better EDC. Structured G10 scales with titan liners would be the optimum (stag is more the Hollywood-Bavaria corner

. I'm sure some would like it, but on an EDC?

).
At best it should be made in the U.S.A or at Germany itself, wich simply says "quality" and is worth the extra cash.
A 3 1/2 " blade is not the optimum for slicing bread. Something between 9 1/2 cm and 10 cm is still a very good EDC length and quite usable for any task.
The ergonomic handle design of the Spyker would be a good start, although i'd prefere a bit more of a finger protecting hilt wich can also be used as a "flipper". Kershaw did a perfect job on that with his Spec Bump (the blade design of both the knives are not my favorite).
This gives the reliabillity that you simply can't hurt yourself, even if you'd stick the knive through your car door, and this is a big step towards a knive you can rely on under any circumstances, wich an EDC should be.
Although it can't hurt to work together with german knivemakers, it's not realy nececcary. I'm sure, a Spyderco-Strider would sell as hell! And not only here

.
Well, for obvious political and marketing reasons i would not call it "Pocket Tiger Tank", but in fact that should be a good description. Maybe "Spyderco KSK" would be a good selling name

.
I hope my thoughts were helpful
