Good solution! You still need to clamp and unclamp the blade every time you want to flip the knife.
Yes, that's right. And it's why I chose this type of clamp rather than a conventional C-clamp. This type can be easily used one-handed. A simple push of the small red button on the handle releases the clamp, and a couple of trigger-pulls tightens it down again. No need to hold with one hand while twisting around a screw-device with the other. With this type, hold the knife with one hand and operate the clamp with the other. Quick, easy, and effective.
Also, where are you clamping onto especially on a small blade like a small Sebenza?
These clamps come in various sizes. When I want to clamp something like the pen blade on a small Swiss Army knife, I just use a clamp with a smaller face and clamp only the spine of the blade, or if need be, the ricasso. I bought a set of three clamps (3 different sizes) for about $10. These cover me for anything from a pen blade to a machete.
