Some blades have warps in them. That perfectly ok if the bevel is a little wider on one side than the other as long as it makes some contact. If it does have a warp and is not making contact at all, there are several strategies you can try including using a more narrow hone. Also, you can add a little more pressure with your finger on the part that does not make contact, but this is not IMHE the best solution. Hope this helps.
