just got the geshi ginga from japanese knife imports never seen or used any knives with a wa handle before so of course it interested me in buying one. i was wondering 2 things. 1. can i use this knife right away out of the box or does it need to be oiled before use? 2. how do i properly care for these handles? i see people sanding them and oiling them but i mean what oils do i use, grit on sand paper, how often to sand handle and oil, etc.. also am looking for new wet stones i currently have a 1000grit wet stone that i use on occasion only. i want to sharpen my own knives more frequently at home and take better care of them but idk where to start. i also do not hone my knife atm. my old hone is rusted. could you please suggest some products? i am also wondering if a knife sharpening guide is best to use for a beginner or are those things not worth buying? i have a blue steel kiritsuke 10inch by shun and the gesshin ginga white steel #2 10in with the wa handle. i also have a mercer i think it's the gensis series that i don't really use anymore.
