I've been known to rock an Opinel as a steak knife. I can't abide when you order a steak out and they bring you a dull ass serrated knife that's been through the dishwasher ten thousand times. I'm partial to the slimline No 10, which is just above the No. 8 in the picture below. The top knife I use for calzones.
But the real beast is this fellow. A birchwood burl Laguiole from Fontenille Pataud.
