Questioning the perfection of the Sebenza? Do I believe my lying eyes? The users need to simply accept how it's put together and learn their expectations are out of place, not the Sebenza.
Pinched bushing? Something got out of CRK that was defective? It's impossible. And should have been sent back immediately.
Legions of Sebenzanistas have advised the above for almost a decade, bluntly, even forcefully. Never question the design, assembly, and use of a Sebenza. It is the Holy Grail of all knives, rightly so, and only the most non-perceptive and completely uneducated could come to any other conclusion.
If anything, it represents the bare minimum as a standard, and is an expression of the knifemaker's craft as all others should make them. They are tolerated only because it makes the comparison so much more obvious.
