I bought my first 'serious' kitchen knife when I was in Japan this past week and did so really knowing utterly nothing about what I was doing other than going by feel. I bought this: https://www.sakaiknife.com/product.asp?id=SH00027 A) Did I make a good purchase (e.g. is it a quality knife)?; B) Anything you think I should know about the type of knife, techniques, cleaning, etc? Until now, I had simply used cutco knives with no interest in anything finer so really I only just learned about different knife types after I made the purchase (I love cooking hence the impulse buy). Thanks for any insight you can provide.
