Large Butter K Gold marker/slicer

I needed a way to mark lines in my Kerry Gold butter. I use 2 Tbsp every morning for Bulletproof coffee. The butter slicer I found here is not strong enough to cut through and I decided I just needed to mark lines and use a butter knife to cut through.

V2 was nice but I couldnt line up perfectly on the butter
V3 I made a bit sharper and put a hole in the middle to poke butter of once you push down.
V4 I put more holes on the outside to line up and also push off.
