This chopping board was made by me in my workshop from Ash & Walnut, with Ash as the main wood and Walnut as the secondary wood. 
 
Rubber feet on the bottom to prevent the boards from slipping when cutting. 
I have finished all my Chopping Boards with a food-safe finish, so they are ready for use.
 
End Grain Chopping Board (Made up of the end grain instead of the face grain). Considered the "King" of cutting surfaces.
Benefits: 
Wood fibres stand vertically, allowing your knives to slide between the grain and reducing dulling.
"Self Healing" This means it is better at hiding the cut marks than normal boards. 
"Enhanced Hygiene" The vertical grain (End grain) prevents bacteria from getting trapped in the wood as the grain is denser and harder.
 
Dimensions:  404x278x38mm (Board Thickness 27mm)*

I also use my Wood Wax on these as aswell, which is made from Mineral oil and Beeswax (from New Zealand), giving them a nice stain finish and protecting them.

Cleaning: Hand wash only! Hot water and soap in the sink. (The glue I have used is waterproof, but please don't use a dishwasher)
 
Refinishing: If the board starts to lose its colour from washing, apply more finish; I would recommend my Wood Wax, but some customers use mineral oil, or even cooking oil.   
 
Any questions, feel free to message me, as I should know the answer, as I make everything myself in New Zealand.
