A simple food safe mineral oil rubbed into the blade when you are finished using it will keep the blade protected from moisture when not in use.
A beeswax based wax or a wood finishing oil applied to the handle every week or so will keep your hardwood stable, water resistant and shiny.
For day to day honing of the knife, I prefer to strop on a leather belt, as opposed to a honing steel as its less harsh on the blade.
For a proper sharpen, use only whetstones, do not use automatic sharpeners or sharpening machines. Invest in a combination 1000/5000 grit whetstone and learn to use it. I love the process, it’s relaxing and satisfying. If you purchase a knife, feel free to come to the workshop and I will give you a free lesson on whetstone.
If you don’t feel like sharpening your own knife, I offer a knife sharpening service. Drop your knife in and I will get it back to you razor sharp in no time.
