Hi Sal,
I'm Austrian, therefore I'm not interested in a German legal knife, but I appreciate your constant effort to satisfy the German market as well.
One thing is for sure: You can ask 10 persons about a perfect designed knife and you'll get 11 different opinions.
To me, the THO 3 (as well as the THO2) seems like a mixture of the Stretch (handle), which is my favourite Spyderco-design, and the Southard (blade). This doesn't mean anything bad, but in that case the design seems unbalanced to me.
Why don't you take an established Spyderco knife and change it to a German legal one (compared to the ukpk)? Would be an easy way and not the worst one (imho). Of course, this can also be done in addition to a new Two-Hand-Operated locking knife.
And - as MojoMC already mentioned (#90) - a "Feststellungsbescheid" is an absolute necessity. Whitout one, you won't sell more of this THO knife than any other "normal" (one handed and locking) Spyderco.
Just my 2 cents...
