A couple more for consideration. The first is a 180mm Mizuno akitada hontanren deba in Blue#2 with saya. It has a white/tan horn ferrule. I have used this deba a good amount, and it has patina. It is a pretty beastly with an 8mm spine, and is a real workhorse. Retail is $380 from jck.

The next knife is a 210mm Tadatsuna kamagata usuba in white#2 with saya. This is a splendid usuba from a top maker that sells for $400 new. The ferrule is a marbled brown/white pattern that looks even better in real life than in the pictures. I have used this knife, and there is patina.
