Hi Kevin,
Yes, I did see it. but as we discussed earlier in the thread, an engraving of a circle is not really "hole", and the engraving can be buffed off.
Hi Immi,
I think it's a good idea, but again more complicated. We have a number of diffferent hole sizes, we would need a plug for each hole size. Also the plug would have to be screwed in. Part of it would stick out which could be used for leverge to open with one hand. Also the policemean could say, if you remove the plug, it's not legal.
I still think the best way to go would be to use a small chamferred hole that would be impossible to use to open the knife with one hand, but could be used to grasp the hole with a thumb and index finger to open with two hands. It would be ambidextrous as well. We would have to make the self close strong enough that inertia opening would be impossible. We would have to leave only enough blade sticking out to grasp with the finger tips, but not enough to be able to grab the hole and drop the handle.
It is a challenging problem to design such a model, but I believe it can be done to serve the German customer and still please the lawmakers and politicians.
