Blades Matched to Your Cutting Station
01 / Printing
Printing & Gravure
Ink metering and edge quality decide print result. Doctor blades and serrated knives for gravure, flexo and label presses.
02 / Corrugated
Corrugated & Carton
Slotting, scoring and cross-cutting knives for corrugated board converting and box-making lines, ground for clean board edges.
03 / Paper
Paper & Converting
Guillotine and circular shear blades for paper mills, printing houses and roll converting lines, sized to your cutter.
04 / Wood
Woodworking
Planer, chipper and veneer knives for solid wood and panel processing, where a stable edge keeps the surface finish consistent.
05 / Slitting

Circular slitting blades for coil, film and foil lines, matched in diameter, bore and bevel angle to your slitting station.
06 / Stainless
Stainless & Hygienic Cutting
Corrosion-resistant blades for damp, wash-down and food-contact cutting stations, where rust-free performance matters as much as sharpness.
About Company
DEKEER manufactures industrial cutting blades in Nanjing, China: doctor blades for printing, guillotine and sheeter knives for paper, slotting knives for corrugated board, circular shear blades, serrated knives, stainless steel blades and tungsten carbide knives.
Forging and CNC grinding happen in our own plant and heat treatment follows your written specification with hardness verified on finished parts, so a custom blade can be produced to your drawing, from a used sample, or simply from the machine model.
Capabilities
Why Manufacturers Source Their Blades From DEKEER
01 — Grinding
In-house precision grindingForging and CNC grinding happen under one roof; heat treatment follows your written specification, with hardness verified on finished parts. Thickness held to ±0.02 mm, straightness to 0.10 mm per 1000 mm, cutting face polished to Ra 0.4 µm.
02 — Traceability
Material traceabilityEvery blade is produced from a recorded steel or carbide batch, and the shipment travels with its mill test certificate so your QA file stays complete.
03 — Engineering
ODM / OEM engineering supportSend a drawing, a used blade or just the machine model. We return a manufacturability review, confirm material and bevel, then sample before production.
04 — Quality
Documented quality controlHardness, dimensions and edge condition are checked batch by batch, and the inspection record is issued with the blades instead of being kept internally.

Frequently Asked Questions
What does DEKEER manufacture?
We are a manufacturer of industrial cutting blades and custom cutting knives: doctor blades for printing, guillotine and sheeter knives for paper, slotting and cross-cutting knives for corrugated and packaging lines, circular shear and slitting blades, serrated knives, stainless steel blades, woodworking knives and tungsten carbide blades. Blades are forged and CNC ground in our own plant rather than sourced and resold; heat treatment follows your written specification and hardness is verified on finished parts.
Can you produce blades to my drawing or from a sample?
Yes — this is most of what we do. Send a dimensioned drawing, a photograph of the used blade with a ruler across it, or simply the machine make and model. We reproduce length, width, thickness, bevel angle and the fixing holes exactly, including slots and counterbores.
Which materials and grades do you work with?
HSS (M2 and M35), tool steel such as D2 and SKD11, stainless steel (420 and 440C), and tungsten carbide. Grade choice is driven by what you cut: a clean shear on film and non-woven, wear resistance on abrasive board, or impact tolerance on heavy material. We will recommend a grade once we know the material and the cutting station.
What tolerances and hardness can you hold?
Dimensional tolerance is typically ±0.02 mm on thickness with straightness held to 0.10 mm per 1000 mm or better, checked on a granite surface plate. The cutting face is ground and polished to reduce friction and material build-up. Carbide grades reach HRA 87–92.5, and hardened tool steel is delivered at the HRC range agreed for your application, with the hardness value recorded per batch.
Which industries do you supply?
Printing and gravure, corrugated board and carton converting, paper and tissue, packaging machinery builders and end users, film and foil slitting, woodworking and panel processing, metal coil slitting, and general industrial converting. See the product series for the blade types used in each.
How do I request a quotation, and what should I send?
Send the drawing or a photo of the blade with its dimensions, the material being cut if known, and the quantity you are planning. If you do not have a drawing, the machine model and a photo of the worn blade is usually enough for us to come back with a specification. You can reach us through the form on this page, by email or on WhatsApp.
Do you supply samples before a full order?
Yes. For custom profiles we confirm the drawing first, then produce a sample so it can be trialled on your machine before the production run. Sample availability, quantity and lead time are confirmed together with the quotation.
Do you support OEM and private-label manufacturing?
Yes. We produce under OEM and ODM arrangements, including your own branding on the blade and the packaging, for machine builders and distributors who need a consistent blade supplied under their own part number.
How are blades packed and shipped?
Blades travel in edge-protected, rust-inhibited packs so the cutting edge arrives intact: individual sleeves or wooden cases depending on size and quantity, suitable for both sea and air freight. Export documentation and shipping terms are agreed at order stage, and we ship worldwide.
Can worn blades be reground or repaired?
In many cases yes. Circular and straight blades can be reground several times while enough body width remains, restoring the original edge geometry. This is usually the cheapest way to extend blade life, and we can advise on regrind intervals for your cutting station.
