Who has one? I just bit the bullet on a white FRN Dragonfly, and am excited and a bit apprehensive to receive it. The blade is the smallest I will ever have used, in your experience, is it still useful? Basically, if I can cut an apple in half without much trouble, and that by inserting the knife and then rotating the apple in my hand, that means the blade is big enough for me. Is that possible? Other comments about it?
