When I was young, I remember my grandpa having a cheap set of grill/BBQ utensils that all had matching wood handles. They were nothing special but I remember thinking it was odd that the knife had an extra long handle to match all the other utensils like the spatula, fork, etc. The blade was only about 3 inches long but the handle was probably 6 or 7 inches. Aside from matching the length of the other utensils in some vain attempt at uniformity, the only function I could think of for such a long handle was to have the option to keep your hand far away from the heat and flames without having a massive 7 inch blade. Eventually I really liked using that tool when I grilled. Haven't seen it in years, no clue what happened to it after he died.
Fast forward to now- I have collected a few really nice grill utensils that I think look great and work really well. Without trying I even managed to stick to a walnut handle motif. But I do not have a dedicated grill knife. The other day I was making cutting boards and I ended up with a left over chunk of walnut wood that was just about the right size to make some new handles. So I bought a cheap oversized steak knife and got to work.
After breaking open the hollow plastic handle, it was funny to see just how cheap it was. The "full tang" was kind of hollow as well. Luckily this will only be used to cut meat on the grill so it's not like I will be batoning with it anytime soon. I used epoxy and then some steel pins that I cut with an angle grinder and peened with a ball peen hammer.
