Farewell to the "Naked Metal" K4. Your last shot at a one-of-a-kind sharpener.

Man, some things are just tough to let go of. The TSPROF K4 in its raw, non-anodized form is definitely one of them.

I still remember when we first dropped this version. Just raw aluminum—no paint, no coatings, just metal in its purest state. It sounds simple on paper, right? But the second you pick it up and catch the light, everything changes. The way the sun hits those edges, every milled surface, every single chamfer... it’s all right there. It doesn’t just feel like a tool; it feels like a blueprint come to life. It’s a "what you see is what you get" kind of machine—no bells, no whistles, just pure engineering.

Under the hood, the K4 is still the most precise beast we’ve ever built. We’re talking three levels of angle adjustment: coarse down to 1°, fine to 0.1°, and micro-tweaks all the way to 0.01°. Those aren't just specs on a sheet; you actually feel that precision in your hands. The new pivot holds rock-solid up to 30N without flinching. Plus, the quick-detach clamps let you take the blade straight to a microscope without losing your spot. You’ve got the Axicube Shift on a Picatinny rail, USB-C charging, and clamps that pull with 300N of force.

We built this thing without cutting corners. And it turned out exactly the way it was supposed to.

But look, reality eventually kicks in. Production economics don’t play favorites, and we’ve made the call to discontinue the non-anodized version. This is it—there won’t be another run.

We have a handful of units left in the warehouse (SKU [TS-K4P240210]). And I’m not just giving you a sales pitch—I mean it: there are literally just a few left. Once they’re gone, they’re gone for good. You won't find them here, through dealers, or anywhere else.

If you’ve been waiting for the "naked metal" version, this is your moment. Not next week, not "down the road." Now.

I’m incredibly proud of what we built here. Honestly? I’m just sorry to see it go.
