I made a magnetic knife block that has turned out pretty well
Started with a nice piece of wood from a tree that was felled in my back, cut out a rough board with a chainsaw, let it dry for a couple of months and got a carpenter friend to plane it.
After that I milled some deep slots into the backside. Used a 32mm long 4mm single flute bit, and it felt like I was pushing the machine to its limits.
Glued in 12 neodymium magnets, each can hold 14kg, but with ~8mm of wood in front itβs closer to 1kg, enough to hold the knifes securely.
I mounted a square steel tube to the wall, the block holds onto this with the magnets.
The wood was sanded and coated with transparent satin laquer, and it was done
