@bear - I've never seen a BBQ knife utensil like that. I've seen old Weber promotional videos where the guy grilling cuts his steaks to see if their done. The knife is pretty cool but how times have changed. Nowadays I think most of us would cringe at the thought of cutting into a steak while on the grill.
@dazzo - I have one of those vintage BBQ trays and a few more. I will start another post about the trays as they deserve their own thread. I believe that design was called "Atomic BBQ". It was around the time of the Jetsons TV show (1962-63).
@Travis - I'm right there with you Travis. The only utensils I would use in my set would be the spatula or maybe the spoon if I was cooking something in the CI Griswold Dutch Oven. I have two restaurant quality spatulas I use. One I acquired from an old military base kitchen and the other at an estate sale. The long handled one was perfect for cooking on my ranch kettle. I've owned them for over 40 years but have no idea how old they really are.
