Update:
After having carried and used now for a little while more I thought an update might be welcomed. The Ti-lock is going strong in every way and when riding in the pocket, the feeling persists that Any smaller of a knife and the occasional desire for a larger blade would pop up and anything larger and it would be too big for the pocket. The Ti-lock just meets that perfect EDC knife ridiculously well. It is hard to describe when one is carrying a knife that is outwardly uniquely and elegantly styled, super qualitatively crafted, function oriented and performance mindedly engineered.
Some of the initial aspects I loved about this knife are still there and even more appreciated and there are some new ones. One of the sweetest things about this knife is the weight. The 3-point something ounces feels awesome in the pocket or on the waistband with any clothing. If one is hiking, biking, or jogging the weight really makes a difference as opposed to a 4+ ounce knife. The stonewash finish is a joy to behold and the anodized Ti spring is holding up well. Not sure if its the spring tension or pivot tension that is loosening up but it makes for opening and closing even smoother than before. Yet still solid in everyway, the Ti-lock is more fun to play with than any of my past sebenzas. It is super easy for the thumb of either hand to find the bronze stud and whip it up like it was begging for it.) Even more fun is the closing action. With the breaking-in period nearly gone, a small flip of the wrist toward the spine of the knife and a flick of a thumbnail and the thing flies closed with a satisfying click. It is great to flick the knife open but I rarely find myself doing it, not for the sake of not wanting to but out of over-carefulness and respect for the lock. I know CRK doesnt condone it with the sebenzas and I wouldnt think they would any less the Ti-lock. Even though it probably wouldnt hurt it, eventually too the titanium cutout in the handle could potentially wear down over time resulting in a less stronger lock. Also the spring clip is gradually becoming easier and easier to depress as it is a heavy sucker. It is quite a bit thicker than the sebenza clip in case the last couple pictures made it hard to see.
Thanks to a good bud, he let me borrow his small unique 21 for comparison purposes since all my sebenzas have moved away. There were a few things I forgot to add in the original post regarding specifics of ergonomics. Very similar to the older regular sebenza models, the edges on the Ti-lock are rounded smooth instead of the defined cut patterns on the current 21 models. Last time you used your sebenza, where did you place your thumb when cutting? Most would say the thumb rests on the spine of the blade, yes? Well, because of the sweet design of the Ti-lock, the thumb actually rests half on the dual thumb stud and spring and half on the handle body. Since there is more surface area where the thumb meets the knife, the feeling is more comfortable and less prone to uncomfortability due to long periods of usage. Same goes for the finger groove on the bottom edge where the middle joint of the index finger rests in the first grip (non-choke up). The Ti-lock has twice the surface area for gripping than which the integral lock on the sebenza dictates. All of these things are quite small factors by themselves but added together they make for a much more ergonomic and comfortable grip.
With all the positives the Ti-lock has going for it, I did notice a few things that could be potentially seen as negative aspects. Due to the nature of the Ti spring lockand where it attaches to the blade via the seated round hole, it does create a non-smooth surface. I suppose bacteria, etc. could potentially get lodged in the grooves there and fester if food preparation is the task at hand and the blade isnt thoroughly cleaned and dried. Microscopic bacteria can live in some crazy environments these days so I wouldnt put it past anyone to argue it. Another potential negative could be the blade size? Yes, I said it and doing so does contradict the previous mentioning of the blade size being a plus. The blade size rocks in many useful ways but could potentially cause a danger alert with non-knife enthusiasts. I have taken the Ti-lock in urban settings like outdoor malls, grocery stores, etc (basically everywhere an EDC would go). I have hesitated many times to whip it out for the simple fact it could make other people uncomfortable. The nature of the design and blue anodized spring do take away from the killer instinct a more hardcore knife might exude but nonetheless the blade is quite large.
As far as my personal CRK collection I dont see the need to own a Large sebenza and especially not a small in the future. I have EDCed both at different times and enjoyed them but the Ti-lock is too ergonomic, too elegant, perfectly weighted, and now really easy to open and close. Personally, I dont believe the small gain in blade length a Large would produce would be enough to sacrifice ergonomics, blade shape, and weight. For all intents and purposes, the sebenza is simplistic elegance. The Ti-lock is just a more advanced version of that.J
