YetiDave you are an absolute bloody legend.
I found this a while ago, and then I could never find it again, I want the 14" one, just because I can.
These are the knives that the BBQ Pit Boys dot cooommmmmmmm use but they add a very VERY hefty surcharge on top just to brand the handle
Our butcher will sharpen it up for me, he's is another legend

, it's alot of effort just for an extra two inches, but then I'm a bloke, and I can at least tell my mates with confidence that I have the biggest chopper, got to be worth it for that
