I am getting ready to take my Journeyman Smith performance test. While doing a final sharpening, I realized my knife has a slight warp in the edge (indiscernible except when you are looking directly down the edge).

Is a slightly warped edge prior to testing something that can fail my blade?

Thanks.

Yes, I think so. Unless it is gradual over the entire length. Any sort of edge deformation during the cutting will fail you; waves, rolls, ripples, chips etc... There would be a burden to prove any deformation was there before the test. If that was proven you would certainly want to be sure the bend was going to obliterate that wave or you would then be in the position to prove it all over again when the knife was presented for the final judging.

Thanks, Kevin. Sounds like I'm redoing it! Better not to risk it.
