JPR - That board is my prototype. All of the cuts were made on my table saw. It is a double glue up. I will post a pic here of the first glue up.
The finish on the board is simply "Salad Bowl Finish" available from Rockler. It is FDA approved for food contact, as is the glue, Tite Bond II or III. As for Knife marks, it isnow in service. It is an end grain board which is easy on the knives. If I mark it up the sanders and more finish are out in the garage. I have three more boards to make for Family members for X-Mas and the self serve santa just brought me a Jointer (6 1/8") and a 13 " planer. The second board which it the pic that I posted is Awsome all the wood is perfectly square and flat. After this, I am going to do a jiotchen Cabinet out of Oak. If I get my router table built in time, I plan to make the raised panel doors. I just found plans last night (free plans at that) for a router table. I have made a kitchen / shop stoll by cutting 3/$" boards down from scrap 2 X 4's.
This is the blank after the First glue up. The board is then cross cut in 1 1/2 inch stripe all strips turned 90 degrees to expose the end grain then every other strip rotated 90 degrees to make the checkerboard and then glue up.
Thank you for the compliment.
