Father's Day is coming up, and after pestering Dad for days and only getting "love and affection" by way of gift ideas we finally got him to admit to wanting a cheese knife. A quick Google has revealed three basic varieties:
a) sets of small knife/trowel implements
b) curvy knives with little forked tongues at the end
c) knives with holes cut out of the middle
Is one of these better than the others? Are they good for different cheeses?
