Thanks. Just placed my order
I was of the understanding bluing was pretty far from food safe, happy to be wrong but I'd properly check before using it
We had a thread on FF a couple of years ago about bluing a knife. I had found a small company that makes a cold bluing product (can't recall if it's Brownell's that Jim used) and inquired about it. One member bought some and tried it. I think he didn't have great results. The bluing took, but didn't protect the blade, and possible wore off.
