I have cleaned the blade up a little more and tried some vinegar but cant see any pattern , would of been nice to see a twist core , nevermind cant win them all !
You might try to etch it after warming the blade. Vinegar can be a weak etchant on some steels. Also, make sure there is no residual oil or wax on the blade before etching. Isopropyl alcohol is my preferred agent for cleaning off any oil or grease before etching.
