A question that I've been asking myself since I started with knives.

For a big knife, I'd have to go with either a DFLE or a BM.
For a smaller knife, I'd go with the SS4 or Ratmandu.

So some combination of:
DFLE BM
SS4 Ratmandu

However, the new Muk and M9 might have to fit in there somewhere.

There are so many good options just within the Busse family, that it's
hard to chose just one combination.

Cheers
