Knife dulls overnight after sharpening

[Ken S]

It seems this edge loss problem is not limited to knives only. I just reshaped a turning skew. With no special attention paid to deburring, it showed a BESS reading of 200. After using it to round one billet, the BESS reading had more than doubled to 420. Apparently, there is something in wood which causes edges to deteriorate.
