Well.........I really like Nick Shabazz. I like his philosophies, and have spent many hours entertained by his channel. However, I feel it is my duty to offer a counterpoint to his terrible, cringeworthy, and mis-informed vid about disassembling and maintaining a large Sebenza 21.
Good grief Nick!: https://www.youtube.com/watch?v=NxE9rrLQlRE
Major Issues with this "alternative facts" version of the Sebenza 21 maintenance procedure:
1 - He clearly has no concept how the pivot bushing works. There is no reason to grease the barrel screws ("Chicago screws"). They do not rotate, and nothing rotates against them. In the Sebenza 21, the pivot bushing is always stationary, and the blade rotates around it. The bushing should never rotate in any case, as it is pinched firmly between the slabs. Greasing the screws is just making a ridiculous mess! The beauty of the 21 is the pivot bushing system. I wish he had taken the time to understand how it works.
2 - He does not understand that the washers should not rotate (spent too much time with bearing flippers I guess). You should absolutely grease the face of the washer that touches the blade, but NEVER grease the back of the washer as Nick does! This may cause the washer to spin against the slab, which will quickly wear-down the washer as it grinds against the bead-blast, altering slightly the tolerances. More importantly, it will possibly add unnecessary grittiness as the washer scrapes along the slab, rather than the smooth side of the blade, and in general makes a giant mess of grease that is not needed. Of interest, on both the Sebenza 25, and the Inkosi, CRK incorporated new design elements to absolutely prevent rotation of the washers (the 25 has a washer tab, and the Inkosi has washer cut-outs that hit the stop pin).
3 - To each his own, but the beauty of the CRK grease (repackaged Christolube) is that it is very thin, and drys to a slippery film, and is food grade, and generally non-staining. Those giant blobs of petroleum grease nick dabs all over his knife, will run out into his pants when the knife warms up, and likely will become some sort of nano-gum in time if you don't eat half of it on your apple. I've tried a lot of options, but CRK grease, or similar greases, are the way to go for this design.
Minor Issues:
1 - The "build it like a sandwich" method of assembling a 21 is really not ideal. If you are going to offer "expert" advice to your large fanbase, give them the straight goods on the easy and successful way to do it!
If you want the right way to do it, check this vid from JDavis. https://www.youtube.com/watch?v=DbPkCAh6E5Q
