Fluorine-coated Santoku Knife 16.5cm - Sharpened to #5000 grit - Instant purchase, no need to comment - Fluorine coating makes food less likely to stick. While not as effective as a knife with a hollow edge, it's still less sticky than a regular knife. And it's easier to maintain than a hollow-edge knife. I cut carrots and sweet potatoes with it, and while they would have stuck all over a regular knife, only a few pieces stuck. - Bulk purchase discount: Deduct 300 yen for each additional knife. 300 yen off for 2 knives, 600 yen off for 3 knives, 900 yen off for 4 knives.
