Multi Groove Bottom Knife

At SHJ KNIFE, we understand that precision starts from the ground up - with your bottom knife. Our OEM and replacement multi groove bottom knives are engineered for accuracy, long wear life, and perfect pairing with your top slitter blades. With over 25 years of blade manufacturing expertise, we help paper, film, and packaging producers achieve consistent, clean slitting and stable material flow - all at a competitive cost.

Each multi-groove circular blade and knife block is produced to meet the exacting standards of your converting lines. SHJ KNIFE blades are fully compatible with machines from leading global brands, including Kampf, Goebel, Atlas Converting Equipment, Dienes, Nishimura, Deacro, and Parkinson Technologies. Our precision-ground grooves ensure proper knife alignment and pressure balance, helping minimize dust buildup and edge fray - common challenges in alkaline-treated paper and high-speed slitting lines.

Whether you need a reliable replacement bottom knife or a custom-engineered multi-groove design, we deliver precision solutions that fit your equipment seamlessly. Simply provide your technical drawing or groove dimensions, and our engineering team will design a blade that matches your system's exact geometry, thickness, and groove pattern. We offer OEM customization services for both individual knives and full groove knife blocks, supporting you with the flexibility required in modern production.

At SHJ KNIFE, quality and durability are the foundation of every multi groove bottom knife we manufacture. Each blade is made from premium-grade steels such as tungsten carbide and HSS, ensuring long-lasting edge retention and consistent cutting results under high-speed production. Our advanced CNC grinding and surface polishing processes minimize friction, vibration, and wear - delivering smooth, clean slitting performance across paper, film, and flexible packaging applications.

To guarantee reliability, every multi-groove circular blade undergoes strict dimensional inspection and hardness testing before delivery. This focus on precision engineering means fewer replacements, reduced downtime, and stable production efficiency - qualities that have made SHJ KNIFE a trusted OEM partner for industrial slitting operations worldwide.

Here's the thing we've learned from years in the field: even the best top slitter knife can't do its job alone. Its performance is locked in a delicate dance with the bottom slitter blade. When that partnership is off-maybe the bottom knife is worn or not quite the right match-you'll see it immediately in ragged edges, unnecessary paper dust, and blades that wear out far too quickly. This mismatch doesn't just hurt your cut quality; it quietly eats into your profits through unplanned stoppages and constant replacement cycles.
