Thank you very much for all of your inputs! Some differences out there, but that's the good one with such a member board! :D I know that it is a low end tanto, but as said... most people started their collection this way. I am aware that there are dozens of better blades out there, but I like this piece. Think I will keep it in it's current condition. The menuki also took my attention, but I can't make them more visible without damaging the wrap.
Again, thank's for your help and better blades will follow...
