I don't really like wood on knives.
I can appreciate a nicely made knife with wooden scales like those above, but I would always choose another scale material for a knife I was buying.
Wood wasn't/isn't used much because of all the stuff a knife has to go through.
Temperature and humidity changes, scrapes and dings, exposure to liquids etc.
I can't imagine wood being a hygenic choice for dressing game or fish, for instance.
I think in the 'olden days', wood was a bit of a cop out handle material used on the cheaper knives, probably for the above reasons.
It's different nowadays with exotic hardwoods and stabilized woods, these problems are mostly mitigated or eliminated, but to me, I just think why have wood when you can have bone?
Some woods look very nice, but how nice would they look after a few years in a pocket with a set of keys?
