Damascus Knife Private Label Specification for Serious Buyers

What Your Specification Must Actually Say

A Damascus knife private label specification should read like a work order for the grinding line, not a catalog sentence. Buyers still send us 3 items: one photo, one target retail price, and “premium Damascus chef knife” on the PO. Not enough. For a real Damascus knife OEM project, that leaves the factory guessing the blade core, cladding, handle density, balance point, logo method, box drop strength and AQL 2.5 inspection level. We’ve seen this go sideways when QC pulled the sample and the buyer flagged the logo position 4 mm off, even though no drawing ever showed the logo position.

Start with the blade. State the knife type, blade length in mm, overall length, blade thickness at spine, taper requirement, edge angle, steel core, cladding material, layer count and HRC band. Example: 210 mm chef knife, 2.2 mm spine at heel, 10Cr15CoMoV core, 67-layer stainless Damascus cladding, 58-60 HRC, 15 degrees per side, satin polished spine, etched pattern visible but not rough to touch. Add where to measure. Our caliper checks the spine at heel, middle and 20 mm from tip, because “2.2 mm blade” means nothing if one side expects a heavy German feel and the other expects a thin Japanese grind.

Then specify the handle. “Wood handle” is the wrong question to ask. Say pakkawood, G10, stabilized maple, walnut, micarta or resin hybrid, then give handle length, thickness, bolster material, rivet type, tang construction, acceptable color range and moisture requirement. Natural wood gives more shade variation; resin and G10 are safer for repeat orders. On one 600-piece run, the buyer approved a dark walnut PP sample, then rejected 37 lighter handles at inspection; the math doesn’t work unless the color range is written before we cut scales on the band saw.

Define branding and packing in the same spec sheet. A private label knife normally needs blade logo, handle logo or end-cap logo, inner sleeve, care card, barcode, FNSKU if selling through marketplace channels, master carton marks, and sometimes REACH, LFGB or FDA food-contact paperwork. At TANGFORGE in Yangjiang, Zhejiang-linked export operations, we treat the approved PP sample as the legal production reference. If the PO says “laser logo” but the sample shows deep etching, production follows the sample unless the buyer corrects it in writing. Simple rule: if it is not written or shown on that sample, do not expect the workshop to read your mind.

Steel, Layers and HRC Choices

Damascus is a welded blade structure plus surface finish, not a steel grade by itself. For kitchen knives, we run a hard stainless core with softer stainless Damascus cladding on most export orders. The core controls edge retention and rust resistance; the cladding carries the pattern after acid etching. If a supplier writes only “67-layer Damascus” and leaves the core steel blank, the spec is incomplete. QC pulled one sample last month that looked fine at 0.20 mm edge thickness, but the PO never named the core, so the buyer had no real basis for approval.

Common core options include 10Cr15CoMoV, VG10, AUS-10 and 9Cr18MoV. For mid-premium retail, 10Cr15CoMoV and VG10 are the normal choices. For entry price ranges, 9Cr18MoV or 10Cr15MoV works when heat treatment is locked and the HRC test is taken on every 200-piece batch. Powder steels are possible, but MOQ and cost climb fast; for a new private label order under 500 pcs per SKU, the math usually does not work unless the brand already sells enthusiast knives. We have seen this go sideways when a buyer asked for powder steel, then pushed back on a US$45.00+ FOB line after the grinding line had made samples.

Layer count gets oversold. A 67-layer blade is common and cost-effective. 33-layer is acceptable for lower price points when the pattern is clean. 101-layer and above reads well in marketing copy, but performance does not jump just because the number is bigger. This is the wrong question to ask. After etching, customers notice cloudy polishing, uneven contrast near the heel, or a pattern washed out by a worn 800-grit belt before they notice whether the blade has 67 or 101 layers.

These are factory reference ranges, not fixed quotes. Handle material and blade profile set the base cost; polishing level, packaging spec, inspection standard and order quantity usually move the price by 15-30%. One buyer flagged a quote gap on a 1,000 pcs chef knife order, and the issue was a typo on the PO: “VG10 60-62 HRC” in one line, “10Cr15CoMoV 58-60” in the artwork file. We ship what is written, so the steel line needs to be clean before sample approval.

MOQ and Pricing That Make Sense

Damascus knife MOQ comes down to the parts you change. If you only run a laser logo on our open blade and open handle, 300 pcs per SKU is a workable starting point; our marking jig is already set, so the setup loss is small. A custom blade profile, new handle mold, exclusive pattern, custom color pakkawood, and printed magnetic gift box usually puts the order at 600-1,000 pcs per SKU. For knife block sets or mixed chef sets, we often calculate MOQ by component, not by finished set, because the 8-inch chef knife, 5-inch utility knife, and block insert each move through different stations. This is where buyers get surprised. The math doesn't work if one low-volume part holds the whole set at the packing table.

At TANGFORGE, our regular monthly capacity is about 280,000 knives across kitchen, outdoor, pocket and Damascus categories. That number does not mean a new Damascus knife OEM project ships in 14 days. Damascus blades still need forging or billet procurement, CNC profiling, heat treatment, grinding, polishing, etching, handle assembly, sharpening, cleaning, and individual inspection; QC pulled one sample last month for a 0.6 mm handle step at the bolster, and that alone sent the lot back to the grinding line. A normal private label lead time is 45-60 days after PP sample approval. New tooling, custom packaging, or compliance testing can add 15-25 days.

Pricing should start with FOB China. DDP quotes look convenient, but they hide sea freight, duty, insurance, last-mile delivery, tariff changes, and warehouse fees. For procurement, ask for both FOB and estimated DDP if your finance team needs landed cost, then compare suppliers on FOB plus a written specification: steel grade, blade thickness in mm, handle material, carton pack, AQL 2.5, and logo method. We have seen this go sideways when a buyer chose a cheaper DDP offer and later found the PO said “Damascus style” instead of real Damascus cladding.

Sampling needs discipline. A basic logo sample may cost US$80-150 per style, and we usually run it on the same fiber laser used for bulk marking. A new handle or blade sample can cost US$200-500 depending on tooling and machining. If the sample is approved, many factories deduct part of the fee from a bulk order. Do not approve by photos only. Check weight, balance, grind symmetry, logo size, box fit, barcode scan, and cutting feel before you release deposit; the buyer once flagged a 2 mm logo shift after seeing the retail mockup next to the actual PP sample, and he was right.

Private Label Branding Decisions

Branding on Damascus knives needs a light hand. A 28 mm logo across the blade face fights the pattern and makes a US$40 knife look like a promo item. For most kitchen knives, we run laser marking 8-12 mm above the heel, usually 18-25 mm wide, after final polishing and before the last wipe-down. Deep engraving stands out more, but if the polishing wheel misses the edge of the cut, QC pulled the sample for black compound left inside the letters. Acid etching can sit nicely with the Damascus finish, but the mask must be tight and the placement jig cannot drift 2 mm from piece to piece.

Decide the logo positions early: blade, handle, bolster, end cap, sheath, gift box, care card, carton. Do not approve all of them because the mockup looks rich; the math often does not work. Blade laser marking is low MOQ and stable, and we can usually set it up from 100 pcs. Handle inlay or a metal badge looks premium, but the CNC pocket needs better tolerance control, around ±0.15 mm, or the badge sits proud after epoxy curing. Embossed gift boxes need plates or molds and usually push MOQ above 500-1,000 pcs, especially with special paper, foam insert, or magnetic closure. We have seen this go sideways when the buyer changed the logo after the box plate was already cut.

For North American and European importers, packaging copy is not decoration. It has to pass receiving. Add SKU number, item description, country of origin, barcode, care warnings, food-contact claims only if supported, and distributor address where required. If you sell through Amazon or other marketplace warehouses, confirm FNSKU label size and placement before box artwork is released. One buyer flagged a 5 mm clearance issue after 1,000 gift boxes were packed; reworking them in China took 2 extra days and killed the savings from the cheaper box supplier. Bad trade.

Our practical view from Yangjiang, China is simple: customize where the customer notices, standardize where they do not. Spend money on blade finish, handle fit, sharpness, box protection, and clean logo work with a 3M tape test after marking. Be careful with exotic packaging shapes, mirror-polished bolsters, unusual handle inserts, and dark etching unless your target retail price can carry the extra rejection rate. We ship better when the spec sheet is boring in the right places.

QC Risks Unique to Damascus

Damascus knives carry more visible QC risk than plain stainless knives. The customer looks at the blade pattern before anything else, so uneven etching, cloudy patches, over-polished zones, rust dots, black residue, and pattern mismatch turn into fast claims. We had a buyer flag 37 pcs in a 600 pcs pilot run because the left face looked lighter than the right after acid wash. Plain 1.4116 can hide a small polishing wave. Damascus cannot.

The first QC risk is false or unclear material. The PO should spell out core steel and cladding steel, not just “Damascus steel”; this is the wrong shortcut to take. Ask for a mill certificate or supplier declaration where practical. For large orders, we run random HRC checks on production blades with the Rockwell tester after heat treatment, not only on the pre-production sample. A workable control plan is 5 pcs per batch or per heat-treatment lot, with results recorded on the inspection sheet. If your spec says 60-62 HRC, do not accept 56 HRC soft blades or 64 HRC brittle blades.

The second risk is grinding and sharpening consistency. The Damascus pattern can hide asymmetric bevels in supplier photos, especially when the blade is shot under a bright light box. QC pulled the sample on our grinding line last month because one side measured 14° and the other side was near 19° on an angle gauge. Check edge angle, burr removal, tip alignment, choil finish, and spine comfort with the knife in hand. For chef knives, edge sharpness can be checked by paper cut or tomato cut; CATRA testing makes sense when the retail line needs lab data. CATRA is not needed for every order. The math does not work on a small MOQ.

The third risk is handle assembly. Gaps between tang and scale, raised rivets, glue residue, and cracked wood are common rejection points, and we’ve seen this go sideways when the buyer approved beauty photos instead of macro shots. Set measurable limits: no visible gap above 0.15 mm, rivet flush within 0.10 mm, no handle crack, no sharp corner, no oil stain on gift box. During shipment inspection, we use a 0.15 mm feeler gauge, fingertip check on rivets, and carton pull from at least 3 pallet positions. For shipment inspection, use AQL 2.5 for major defects and AQL 4.0 for minor defects. For logo, barcode and safety defects, we prefer 100% check because one wrong logo can make the full carton unsellable.

Compliance for EU and US Orders

Compliance changes by market and sales channel. For kitchen knives touching food, our EU buyers usually ask for LFGB or a food-contact declaration, then REACH checks for restricted substances in handles, coatings, packaging inks or plastic parts. US buyers often ask for FDA food-contact conformity for the steel, handle and coating, but the file format is not the same as EU paperwork. We run material declarations by SKU because one black POM handle and one walnut handle can need different backup documents. If you use wooden handles, importers may ask about fumigation, 8-12% handle moisture control or FSC claims. Do not print FSC unless your chain of custody supports it; we have seen a buyer flag one FSC logo on a color box during pre-shipment artwork review.

For outdoor, hunting, pocket and tactical Damascus knives, the rules get messy fast. Blade length, locking mechanism, assisted opening, sheath style and local import rules can change by country and even by state. A custom Damascus knife legal for one distributor can be blocked for another. Your specification should list open length, closed length, blade length, lock type, opening method and sheath material. We ask for these numbers in mm on the PI because the shipping team should not be guessing at customs. This is the wrong question to ask after mass production, especially when QC pulled the sample and the actual blade came out 3 mm longer than the approved drawing.

Factory audits matter when you sell to retailers. BSCI, ISO 9001-style quality systems, social compliance files and metal detection controls can be requested before onboarding. TANGFORGE was established in 2008 and has about 240 employees; we are used to procurement teams asking for QC flow charts, inspection reports, packing photos and production status updates. On one retailer file last year, the buyer wanted 3 packing photos per carton type plus the AQL 2.5 report before balance payment. A good Damascus knife factory China partner should be able to discuss corrective actions from the grinding line and final inspection, not just send glossy product photos.

Labeling is another common miss. “Made in China” or “Country of Origin: China” must be visible according to your market and channel requirements. If your company is registered in Europe but the knife is made in Yangjiang, China with packaging printed in Zhejiang or another China packaging hub, do not blur origin claims. We check this at artwork stage because one PO once spelled it “Made in Chian,” and the buyer caught it only after carton printing. Customs problems cost more than honest labeling. The math doesn't work.

How to Approve Bulk Production

The safest approval process is simple and strict. Approve the CAD drawing and written spec first, down to blade length tolerance in mm and logo position. Then sign off material chips and handle pieces if the color or Damascus pattern affects selling photos. After that, approve one PP sample made on the same grinding line we will use for bulk, not a bench-made piece from the sample room. Release bulk only after your team checks the knife, inner box artwork, EAN/UPC barcode scan, and outer carton marks; last month a buyer held 480 cartons because the PO said “matte black box” but the approved artwork file said “soft-touch black box.”

For a Damascus knife private label specification, the PP sample needs the real steel construction, the agreed HRC target, the actual etching finish, final logo, final handle material, and final packaging. A hand-polished showroom sample is the wrong reference if bulk will run on a 240-grit polishing wheel, a 6-minute ferric chloride etch, or a different G10 handle batch. We keep one sealed golden sample in the QC cabinet and ship one to you. During final inspection, QC should compare production against that sample under normal white light at the packing table, because the grinding line lights can hide a weak etch or a wavy spine.

Your PO should define what happens when defects exceed AQL. Write the remedy before deposit: 100% sorting by our QC team, rework with a new inspection date, replacement pieces in the next shipment, or a line-item discount if the defect is cosmetic and your sales channel accepts it. The math does not work if this argument starts after the goods land in your warehouse. Factory inspection photos help, especially close-ups with a caliper and HRC report, but for a first launch or a 2,000-piece order, we still recommend a third-party or buyer inspection before loading.

For first orders, do not launch six SKUs with six handle colors, three steels, and four box types. We have seen this go sideways. Start with one or two hero SKUs, such as a 210 mm chef knife plus a 3.5 inch paring knife or 8 inch slicer, and set a practical MOQ for each so the handle batch and packaging print stay consistent. Once reviews, returns, and sell-through are stable, add the next shape. Damascus knives reward patience; the brands that win are usually not chasing the loudest pattern, they are the ones that keep the same edge feel, etch depth, and packing standard from reorder to reorder.
