sevenedges and Django,
If you guys were asking me about my Sebenza experiences, it was chipping on two of them. All three at the time belonged to two friends. One has a Large Classic that kept chipping after moderate use and was a hard to get sharp. The other friend has a Small Classic and Large.The Small Classic was chipping but not as much as our other friends Large Classic and after a few sharpenings, stopped chipping. The Large had no problems and was working great for us.
My friend who owns the Large Classic told me about two weeks ago that it seems his is calming down and not chipping anymore.
So, the "problems" seem to be clearing up or have cleared up. Looking forward to picking up one of my own. Hopefully soon.
