Secondly, this kit is ideal for taking with you outdoors or simply when visiting a friend.
Thirdly, the K4 is perfect, as is the case.

Uncompromising Precision Meets Ultimate Protection: The TSPROF K4 Black Bundle

The Apex of Sharpening Technology: TSPROF K4 Black

The K4 Black represents the pinnacle of modern sharpening systems. Built with zero tolerances and unmatched rigidity, it features a fully redesigned turning mechanism that allows only 0.1° of arm deflection under 30N of force.

When you are working with premium steels and expensive custom knives, there is no room for error. The K4 delivers with a three-stage angle adjustment system—rough, fine, and an ultra-fine micro-adjustment up to 0.01°. Paired with the Axicube Shift electronic angle finder and finished in a sleek, tactical matte black anodization, the K4 Black is the centerpiece of any serious sharpening workshop.

Vault-Like Storage: T4814 Protective Case & Custom EVA Insert

Because the K4 is so heavy and precise, storing or moving it requires specialized protection. Loose parts banging together can damage threads, scratch the anodized finish, or compromise the electronic angle finder.

To solve this, the bundle includes the TSPROF T4814 protective case. It acts as armor for your sharpener—impact-resistant, dust-proof, and highly durable. Inside, we have replaced standard pluck-foam with a premium, high-density EVA insert for K4.

• Immobilized Protection: The dense EVA foam is CNC-cut to perfectly hug the massive base, rack-and-pinion lift, clamps, and abrasives. Even if the case takes a hit, the heavy metal components will not shift or grind against each other.

• Workshop Organization: Say goodbye to cluttered workbenches. The custom tray ensures every hex key, clamp, and stone has a dedicated slot, cutting down your setup and breakdown time.

• Longevity: By keeping your K4 Black sealed away from workshop dust and moisture when not in use, you extend the life of the moving parts and preserve its flawless matte finish.
