Pure tung oil is supposed to be food-safe.
Tung oil Finish on the other hand is not food-safe.
Check the ingredients, if it contains other than Tung Oil then it's not food safe.
I thought Razorstar cut a bit slower at first compared to Blaze, but it just keeps cutting after 1 whole blank is finished.
While the Blaze is just toasted after 1 Blank. It could still work for slight thinning, but not as effective.
After a long time of grinding during my off time, I finally finish grinding with one of the knife.
Slight convex almost a bit hollow on the Hira or face.
Here are some test cut with edge off the best grinder.
Just need a handle and fit and finish
i tried to use the flat plate before and it took a long time to get the geometry that I wanted.
i tried to use the wheel, and finally, I could get the slight convex-flat bevel and less wedging on my final product.
also, different belts act differently.
i wouldn't recommend using that hard-wax oil for a cutting board, but it is a nice oil for a handle finish.
use a white pad while applying it and wear gloves. it is really pain in the anal to clean it.
