New Knife design - what do you think ?

So drilling a hole is illegal now? Hahaha
Anyways good design, I like the new blade shape even more

I don't think Busse has a patent on it, or a trademark. I know plenty of makers that drill that hole, do as you want Konrad.

Then this is final version, and I starting to make prototype

For a start I think about NC6 steel 6mm or N690 4,5mm .
