Ripple is a great example of the IK bearing system, this is the smoothest pivot system I've ever tried, my only complaint is that it's not lint friendly, a small but if lint is enough to keep the liner lock from completely engaging and unless you're skilled mechanically to some level is a pain for most to take apart and clean.
Carrying the role Ripple in a sheath would prevent any lock-up issues.
Put a magnet on the blade. Helps keep the little balls from going all over the place.
Also, CRKT sent me a bag of about 75 little balls when I asked them for some after I took apart my Eros without first putting a magnet on the blade.
Do you want IKBS in particular, or just a bearing pivot? If the latter, I would take a look at the Buck 830 Marksman. Good steel, strong lock, and extremely smooth.
What is the difference between ikbs and just a bearing pivot?
I have a shop and have been a mechanic/machinist for many years ago I have a tacky Matt I use for the little bearings and a pair of angled titanium tweezers I use for the ball bearings. The only reason I would avoid using a magnet is that the bearings will become magnetized and this will attract any ferrous metal chips, filings anything magnetic and it could cause problems with smoothness of opening our even premature failure, (probably not an issue but because of the work I used to do it can be a problem)
Caged/captured bearings, this isn't an issue because there's no chance or need to introduce the bearings to a magnetic field. You don't have to be a machinists/mechanic to work on your IKBS knife but having the basic concepts of taking apart and reassembling something you've never seen before do help.
One of the first things I'll do when working on anything is to start with a clean uncluttered work area and I'll put a white cloth down so I can spot wandering parts when reassembling.
