I am a looking for a purchase that will last me a long time. I have been reading around on this and a couple other forums and have narrowed down my choices to a few different selections. Also, I would have to learn how to sharpen on this knife, and would like a recommendation for sharpening tools. My decision is down to a 240mm Fujiwara FKM Gyuto, a Tojiro ITK 240mm Gyuto, or a MAC Mighty 8 1/2". I do not have a knife store around me, so it would be a blind purchase. Any advice would be very helpful.
