Single slicer struggles
I had previously posted about a bolstered knife, I managed to remove a decent chunk of the annoying bolster using a file and a coarse diamond plate.
But now I am stuck getting it sharp, I think my technique is decent, I have a matching 8” Wusthof chefs knife that I have got and kept sharp enough to cut newspaper against the grain. However, this pairing knife I simply cannot get it sharp.
I’ve got a large burr using a 320 grit diamond stone, using roughly a 14-17 degree angle, flipped the knife and got the same on the other side. At that coarseness, it’s incredibly easy to feel for the burr. Then progressed onto a 1000 grit Naniwa, carefully polished with four strokes on each side, to upgrade the scratch pattern. Now I spend a long time to remove the burr. I use a flashlight between each single pass, switch sides each time, doing edge leading tip to heel passes. An eternity later, the burr was completely removed. Then a few passes on a 1-micron infused leather strop.
After all of this, the knife simply isn’t anywhere near as sharp as one would expect, not even close to it’s larger 8” cousin. It can barely start to cut through cheap A4 printer paper, it’s hopeless to even attempt to test it against some newspaper, and not a chance in hell it would ever cut against the grain.
So, I tried again, using only the 1000 grit stone, created a burr down the edge, flipped and repeated, again the painfully slow burr removal, tested it and it’s still what I, and the rest of you, could consider blunt.
Can anyone point me in the right direction. Are my angles all messed up, is the knife beyond repair – given how much material has been removed from the original edge, or am I missing something else obvious?
