Sorry for the late response and my conclusions about Carters knife terms because, as it seems, I don´t quite follow his nomenclature.
My old Carter was called wabocho I´m sure but that just means traditional japanese knife with wa handle (or so).
Funayuki is supposed to be like a santoku (flat-ish) but with a more pronounced higher off the board tip. (as I understand it)
Here is a picture of a typical Carter funayuki (top knife; a brilliant petty BTW):

Just a few months ago I bought a used Muteki from Harbeer and looked at Carters website only to see it is called funayuki as well although it looks very santoku-like and very different to most of his "funayukis"

Anyways,
TLDR, here are some pics of both.
The old one obviously wasn´t "taped" while thinning and still has a many months old chip in the blade where a banged it into a aluminium pan..
Both knives are great performers. Both ~20cm the Muteki quite wide at the heel with 57mm, the old one 48mm.
The latter still has the original plastic ferrule Carter used to use back then!
