cutting board comparison

This 12×20 walnut cutting board is the perfect addition for your kitchen tasks! This particular size is one of our favorites because it fits so well on various countertops. The size can easily slide over your kitchen sink to scrape off all the scraps from your cutting tasks. This makes it perfect for professional restaurant settings as well as the average home alike and is why we strongly recommend one of our beautiful and more compact boards for every kitchen guaranteed. The 2” thickness of our cutting boards and butcher blocks means that they are impeccably durable and shock absorbent likewise. 

The stunning swirling and neutral fine grain of walnut wood means that it not only functions as a beautiful piece of decor and a great alternative for other rare woods but is incredibly durable and long-lasting as well. This means that your walnut wood cutting board is sure to be able to withstand daily use and potential fall or water damage without bending, warping, chipping, cracking, acquiring mold on the board, or drying out for years. 

On the Janka hardness scale, Walnut ranks 1,010 lbf or 1,010 Janka. With this said, it is harder than cherry wood but not quite as hard as maple wood. Walnut wood isn’t just durable and shock resistant, however, as it also is self healing which is particularly beneficial for cutting boards and those that use them. With cheaper wood and plastic cutting boards, the common mistake of cutting in the same spot daily leads to deep grooves in the board that trap food particles and contaminate all food cut on the board moving forward. However, with a self healing board, these grooves repair themselves over time and ensure a safer kitchen prep experience without the risk of food poisoning or foodborne illness. 


Walnut wood is also sustainable to grow, produce, manufacture, and use for countless wood projects alike. This is why this wood can be seen in hardwood flooring, construction, car interiors, gun stocks, guitar bodies, cabinets, veneers, countertops, and various other wood items including cutting boards. This is also why many people use this wood as an alternative to less sustainable woods as well. That’s why walnut wood is not only considered incredibly beautiful and strong but eco-friendly, long-lasting, and cost-effective likewise making it the perfect wood for cutting boards guaranteed.
