My spouse makes butcher block from scratch and it is quite challenging. Who am I to say if you are up to it, but it is more than just glueing strips of wood together.
For some reason, maybe to do with the wyoming climate it is very hard to keep it from drying out. Tung oil every couple of weeks.
And finally, I am not the sanitary police, but I wonder about the ability to keep the surface even moderately germ free.
My 2 cents.

Thanks, mfwolfe. I knew butcher block has to be oiled, but I was under the impression it had to be done with something edible; is tung oil suitable?

Recent research has swung back to wood surfaces for germ control. Apparently it is easier to clean it with bleach and scrubbing than to disinfect plastic surfaces.
