The are adhesive-backed tapes which you apply to an aluminum tape blank (sold separately, see below) to apply a final mirror polish. This is for true polishing -- keep in mind that 6000 grit is like 18000 grit Japanese! So this is more like stropping than sharpening at this stage of the game. If you're going to use this tape, it might make sense to also use a lower (2000 or 3000) grit tape first, as part of a two-stage polishing.
In my opinion, this type of edge is more useful for thin bladed knives where you want maximum slicing action. 15 tapes per pack. |
