We need to replace about 15 Thunder Group cutting boards. There is a large price differential between Thunder Group 12 x 18 boards (about $7 or so) and Carlisle (over $20).
Are the Carlisle boards that much better than Thunder Group? Do they resist grooving, etc. better? Do they last all that much longer?
Also, I see that Carlisle makes a Cutting Board Refinisher. Is that effective and worth purchasing?
