Large Butcher Block Island made of hard maple with custom walnut star inlay. This island has endured very hard daily use (including, but not limited to, an attack with a screwdriver and hammer by a mischievous child). Rock maple endures mistreatment stoically, shrugging off the effects of chopping and slicing. If it does get scratches or dings over the decades, it's a simple matter of sanding the scratches out to get the block back to new condition. I finish all my cutting boards and countertops with pure, food-grade mineral oil. I also only use Titebond 3 glue, which is EPA-approved as food safe and waterproof.
I've made over 500 cutting boards and butcher blocks in my shop by hand. It could be a lot more than that. Once I reached a certain point, it didn't make a lot of sense to keep track anymore.
Dimensions: cost depends on size and inlay.
