Ah I think I have just seen the bane of allmost ALL kinfe users here. Cutting dinner on a "CERAMIC plate" I tell everyone that buys one of my blades, to NOT cut with your kinves on a ceramic plate! Why? Its harder than the steel. Brittle yes, but close to as diamond hard. This had dulled more knives in the world than anything else I can think of. Its the same with dirt, if you pull your edge through dirt, you're gonna hit small stones that are, yep harder than steel. One story this reminds me of is, about 12 years ago I sold one of my customs to a good friend, he came back about a week later with the finish and edge very dulled. (None of my blades had ever had this problem before) I asked him what he was cutting. He said "About 300 rolls of sod, at the sod farm" Hum sod=dirt=stones=dull. So to keep a good edge, don't cut on a harder surface than your blade. Just a tip, so you can keep yours. enjoy edgy:thumbup:
