I just noticed these by Ruike. IMO, this is what a SAK should be or at least should have evolved into by now. One hand opening operation, removable G-10 scales, integral glass breaker on most models, locking blades AND the most important a semi-deep pocket carry clip. Steel is Sandvik 12C27, I'm planning on getting a Trekker LD-32B. They also have a Criterion collection without the thumb stud for one hand operation but all the other multi-function tool add-on configurations.
