Direct OEM replacement

The K1 is a true drop-in for the Zund Z1 (3910105), Esko BLD-KC101 (G42438499), and Gerber MCT KC1 (895001). Same form, same fit, same geometry. Look up your current blade part number and order with no holder changes.

What is kiss cutting?

Kiss cutting means the blade cuts through the face material, the vinyl, film, or label stock, without cutting through the liner underneath. The finished piece peels cleanly from the sheet. The K1 is built specifically for kiss cut work. It is not a through-cut blade.

Fine grain tungsten carbide

The K1 is ground from fine grain tungsten carbide, which holds a sharper edge longer than standard carbide. In high-volume vinyl work like labels, vehicle graphics, and window graphics, that means cleaner cuts at depth and fewer blade changes per shift.

Common questions

How do I know the K1 fits my machine?

Look up your current blade part number. The Zund Z1 (3910105), Esko BLD-KC101 (G42438499), and Gerber MCT KC1 (895001) are all direct fits. Not sure? Contact us before you order.

What materials does the K1 cut?

Self-adhesive vinyl, polycarbonate, polyester, masking film, window prep vinyl, magnetic media, transfer paper, and 3M VHB. If you are cutting something thicker or more aggressive, a different blade geometry is the better call. Reach out and we can point you to the right option.

What do the cutting angle and wedge angle mean?

The K1 features a 35° cutting angle and a 40° wedge angle. The 35° cutting angle helps the blade track smoothly through the material with reduced drag, while the 40° wedge angle provides the ideal balance of sharpness and edge durability. Together, they deliver clean cuts, excellent detail reproduction, and consistent liner protection in demanding production environments.

How do I know when to replace the K1?

Cut quality is the fastest indicator. If edges are dragging, tearing instead of cutting clean, or the blade is not releasing from the liner consistently, it is time to swap. Blade life varies by material, cutting depth, and machine speed.

Getting the most from your cutting table

A fresh blade is a good start. But if you are going through blades faster than expected, or cut quality has become inconsistent, the blade is rarely the whole story. Cut depth, speed, pressure, and machine condition all affect how long a blade lasts and how clean it cuts.

It is worth asking: When was your machine last serviced? Are your parameters dialed in for this material? Is this the right blade geometry for what you are cutting? Could your operators use time with someone who runs these machines every day?
