The likeable Russlock...
This is a little bit of an oddity. Case married the traditional slipjoint type pocket knife with a sturdy linerlock. Nothing new there. And then they added the unusual feature of a curved and jimped lever, to allow one-handed opening. The other reviews make valid observations, and it was interesting to read the historical background. I have to agree, there is a little amount of rotational blade play in the open and locked position. I think that it is due to very slight flexing of the backspring, despite the fit and robust thickness of the linerlock. However, the design is quite secure, and in actual practical use, this pocket knife works just fine. It seems to me that the Russlock was never intended for rapid opening. It takes a firm grip and a little care to lever the blade open with a fair amount of pressure from one's thumb or forefinger. The firm backspring that keeps the blade securely closed in a pocket also means that the effort to open a Russlock is significant. So it was a bit of an adjustment to learn to open and close this model smoothly. Take these opinions with a grain of salt; it's merely my thoughts. I do like the Russlock design, actually. It makes a dressy single blade pocket knife, nicely finished to Case's usual gleaming standard. At present, my collection has three Russlocks; one with Magenta jigged bone and clip blade, one with Jigged Rosewood scales and clip blade, but without a bolster at the bottom of the handle, in what is referred to as a bareheaded' configuration, and finally an interesting drop point Russlock with handsome jigged Crimson Bone scales. The Rosewood model is noticeably lighter. The overall looks of a clip blade Russlock reminds me of the original Schrade Sharpfinger fixed blade pattern from the 1970's. That had a similar dramatic sweeping curve to the blade profile, an ergonomic handle, and featured an intrinsic thumb rest. All in a compact design. So in some respects, the Russlock is like a folding pocket version of the Sharpfinger. The jimped lever has not worn a hole in any pockets, and a Russlock carries comfortably around the house. Excluding the lever, the closed length is 9cm or 3-1/2 which places the Russlock size-wise in familiar SAK territory. The weight is comfortable and reassuringly hefty but not a burden. What one person finds desirable in a pocket knife may not necessarily suit the next person. But if you are interested in an unusual design from a respected cutlery manufacturer, a Case Russlock is certainly unique. I like mine; enough said. Thank you to Heinnies for making this pattern available.
