I'm not a knifemaker, but I laser cut these two out of a big sawmill blade to a rough design I made up and a mate ground and heat treated them for me. For personal use only, I wanted a big knife for skin removal and purely as a novelty, a modified Tracker "survival" knife...

...the top "Nessmuk" style has a 110mm blade and I'll handle it with some left over wood to match one of my rifle stocks. The lower knife is 280mm long and gets an Iron Bark handle with a small of the back sheath with pocket for a diamond sharpener.
