I purchased the Carolina walnut end grain cutting board and a matching sidekick. They're absolutely beautiful, so beautiful in fact that I have been having trouble convincing myself to use them because I don't want to mark them up. I have started overcoming my worries.
We live in Phoenix and I have been surprised by how much mineral oil they slurp up. I set a weekly "to do" to oil them.
I wanted feet on the sidekick but it is a tiny bit wobbly (any suggestions on how to fix it?); the Carolina board (also with feet) is extremely stable.
