I just got my first knife from CRK, a large classic. I'm impressed by how over-engineered this tool is.

I'm curious about the efficacy of the lubricant that CRK sells. Does it perform markedly better than others? I have been using Mpro7 products on my weapons for years, and wonder if I need a different lubricant for the Sebenza.

I'm also curious about the bolts. If I tighten them fully the knife is extremely difficult to open. I am concerned about the bolts working loose. Does this occur?
 
People use a variety of lubricants, as long as you are happy with the effect, use what you have.

If you tighten down the screws and it's hard to open then there is a problem as the screws are supposed to be tightened all the way down.

More then likely, the pocket clip is too tight, you're holding it and adding pressure to the lock bar and it needs cleaned and relubed. This is a classic CRK issue, if you scroll down the threads you'll find discussions on the subject.
 
Like Dave said... if it's a high quality weapons lube, it should be OK on the Sebbie. I've used CRK grease but I prefer something like Tuff-Glide or Break-Free.

I tighten all of my Sebbies down when they're d/a & cleaned. I've never had one that was harder to open because of the screws being properly tightened. That sounds like a different issue. Again, as Dave mentioned, maybe the clip is putting too much pressure on the lockbar.

I wouldn't worry about the screws working loose if they're properly tightened. Out of 7 Sebenzas, I've never had that problem.
 
Try polishing the washers on the side that faces the blade. I had the same problem and somebody suggested that to me. It helps but it is still a little on the stiff side.
 
A clean knife and a dab of a good lube, the lighter the better, now and then, does the trick.
 
I just recently got a large sebenza and for the first few weeks it was a little hard to open, after a few weeks of opening and closing it now works perfect. I ordered the CRK lube and it is pretty good but I also have been using a product called gun butter and it is excellent for a knife lube. I have only taken the sebenza apart one time and it was only the removal of the blade, I did not take the scales apart. Be careful with the screws if you strip out the allen heads you are in trouble. The allen wrench is harder than the screw heads and if you round them out you won't be able to remove the screws. You should only have to tighten them down until they botom out no more.
 
Did they change something with the 21? I had a regular small sebenza and it was really difficult to open and gave my thumb blisters. With the large 21 it is effortless and easy to open.

I've had two small regulars and they have both been beasts to open. Overcoming the ball detent seems to be the problem for me. OTOH, all of my classics in both sizes are very easy opening. I think the difference is the positioning of my thumb behind the thumb lug. It's easier to get in a good position with the deeper cutout of the classic/21 series than it is with the regular series.
 
Sometimes I use my knife for food preparation so I use cooking oil to lube it. Nontoxic and all.
 
I have had mine 7 years now, 5 of which working offshore commercial fishing (not quite as intense as the gus on tv however) and lubed it with rem oil spray when working in salt water (with marine tufcloth wipe) and since only used yuf glide liquid on the working pieces and washers with just fantastic results. There is no rust anywhere on the knife at all, and to eb honest for a couple years I only washed it out with water and relubed, it never came apart!

Testament to the $160 I spent to buy the knife (used 7 years ago) and the fact that I have not bought a sing knife since. BEST money I ever spent on a blade, in fact, it took me OUT of the hobby, I dont buy knives anymore and rarely visit the forum (I am an original first 100 members I believe).
 
I used to use a liquid lube, but now I use a dry silicon spray and have never had such good results!!!!
 
Look on the net for info on Nano Lube. It's industrial diamonds in a synthetic
oil. These diamonds are so small that it takes 25K to match the breadth of a
human hair. 8cc of the +P is $37.- ( NDN70-ATM+P ). Not cheap but neither
are Sebenzas. The Swiss are using it in their watch movements. It is the
best I have ever used.

The swiss are using synthetic oil made by Bergeon and others in their watch movements, designed specifically for each watch part. Almost all the mechanical watches are using +3-4 different oils. IMO, for the price the CRK lube is the best, I have been using it for some months for my Sebbie and other things and it does perform well ;)
