Chef Knife Private Label Specification for Serious Buyers

Start With The Knife Positioning

Before steel grade or MOQ comes up, decide where this chef knife sits in your range. A supermarket promo knife and a premium gift-box chef knife should not use the same spec sheet. If the buyer only pushes the lowest FOB, the math does not work; the factory has to pull cost from blade thickness, handle polishing, edge consistency, box protection, or final inspection minutes. We see this on the grinding line: changing a blade from 2.5 mm to 2.0 mm at the spine saves money, but customers feel it the first time they chop onions.

For a normal 8 inch custom chef knife, define the target retail price first, then work backward. A knife retailing at USD 19.99 cannot carry the same steel, full tang finishing, gift box, and QC burden as a USD 79.99 knife. Good suppliers in Yangjiang, China can make both. We need the target lane before we quote. Last month QC pulled a pre-production sample where the PO said “satin handle,” but the artwork file showed mirror polish; that one typo added 12 days vs 18 days to sample approval because the buyer had to re-check the shelf plan.

A basic positioning brief should include:

• Sales channel: Amazon FBA with drop-test packaging, retail shelf with hang tag, foodservice distributor, promotional gift, or DTC brand.
• Target retail: for example USD 24.99, USD 49.99, or USD 89.99, with the expected FOB gap clearly marked.
• Warranty promise: 1 year, 5 years, or lifetime limited warranty, because the handle rivet and edge spec need to match that claim.
• User type: home cook, culinary student, professional kitchen, or outdoor cooking customer; the buyer flagged this before on a 5000 pcs order after testers used the knife on bone.
• Compliance market: EU, UK, US, Canada, Australia, or mixed markets, with carton marks checked against the PI before mass packing.

This positioning sets the technical limits that make sense. A hard 60-62 HRC edge sounds premium, but it is less forgiving if users cut frozen food or twist the blade. A softer 54-56 HRC promotional chef knife can take more abuse but loses edge retention faster. For 7 out of 10 private label chef knife projects we run, the practical middle is 56-58 HRC for German-style stainless steel and 58-60 HRC for Japanese-style stainless or Damascus constructions. This is the wrong question to ask if the buyer starts with “what is your best steel?” before telling us the retail price and complaint tolerance.

Blade Specs Buyers Must Lock

Blade specs are where loose buying words turn into scrap. “Sharp,” “heavy,” and “premium” should not sit on a PO by themselves; put numbers beside them. For chef knife OEM, we freeze the 1:1 technical drawing before mass production, even if the buyer chooses our stock mold. Last March, QC pulled 32 pre-production samples because the PO said “same as sample” but the approved PDF showed a 2 mm lower heel.

For an 8 inch chef knife, typical blade length is 200-210 mm, total length is 320-340 mm, spine thickness at heel is 1.8-2.5 mm, and blade height at heel is 43-50 mm. A Western chef knife usually needs a stronger spine with a convex or flat grind. A Japanese-style gyuto profile can run thinner, lighter in hand, with a lower edge angle. We check this on the grinding line with a digital caliper, not by eye, because 0.4 mm at the spine changes the whole cutting feel.

Lock the grind type and edge process. This is the wrong question to ask: “Can you make it sharper?” Ask for the edge angle, burr removal method, and inspection standard. Belt-sharpened edges run fast, but a tired operator can burn the last 0.2 mm of the edge if he leans too hard on the 800 grit belt. For mid and premium chef knives, we run a controlled final edge with burr removal, then paper-cut or tomato-cut checks. CATRA testing makes sense for higher-volume programs; for 800 pcs, a clear in-line sharpness check plus final inspection is usually the better spend.

Specify logo placement and marking method before sampling. Laser engraving is the normal private label choice for 300-500 pcs, and we ship that without logo tooling. Deep etching or stamped logos need a fixture or die, so the MOQ and lead time move. We have seen this go sideways when a buyer approved a left-face logo in artwork, then sent a PO saying “right side” in one line item.

Steel, HRC And Heat Treatment

Steel choice is not just a marketing line. It changes how the blank runs through the 80-ton punch press, how much stock the grinding line removes, where heat treatment lands, and how many rust or edge-chip complaints come back after shipment. A chef knife private label specification should name the steel grade clearly, not just “German steel” or “Japanese steel.” We have seen a PO say “German 1.4116” in one line and “Japan steel” in the artwork file; QC pulled the sample because production had no controlled material target.

For value and mid-market chef knives, we run 3Cr13, 420J2, 5Cr15MoV, X50CrMoV15, and 1.4116 on regular blanks, usually from 2.0 mm to 2.5 mm sheet. For higher-positioned chef knives, buyers ask for AUS-10, 10Cr15CoMoV, VG-10 core Damascus, or powder steel, but the math does not work if the retail price still sits at USD 19.99. Be careful: premium steel will not rescue bad heat treatment. A properly treated 1.4116 at 56-58 HRC can beat a poorly treated “VG-10 style” blade when the buyer’s warehouse starts opening return cartons.

At our Yangjiang factory, we normally write an HRC band instead of one exact number. For example, 1.4116 at 56-58 HRC, 5Cr15MoV at 55-57 HRC, AUS-10 at 58-60 HRC, and VG-10 core Damascus at 59-61 HRC. Promise “exactly 58 HRC” on every blade and we already know the inspection will go sideways. Heat treatment has controlled variation; on one 500 pcs pilot run, our Rockwell tester showed 57.1, 57.6, and 58.0 HRC across three blade positions, all acceptable under the agreed band.

For EU and North American markets, build corrosion checks into the spec. A mirror-polished blade hides fewer grinding lines but shows fingerprints fast, especially after the packing team handles it without fresh gloves. A coarse satin finish can look clean in photos, but if the belt mark is too deep, moisture sits inside those lines. We normally recommend a neutral salt spray or practical wet cloth corrosion check for new steel/finish combinations, especially on black oxide, titanium-color PVD, or coated tactical-style chef knives; last month the buyer flagged orange spots after 24 hours under a damp cloth test.

Compliance belongs in the material spec, not in a late email after cartons are sealed. For food-contact kitchen knives, importers request LFGB for EU, FDA food-contact declarations for the US, REACH for chemical substances, and sometimes Prop 65 review for California distribution. Ask for these documents before production starts, because certificate checking takes 3-7 working days and a missing LFGB line can hold a finished 1,200 pcs order in our packing area.

Handle Construction And Balance

The handle is where 7 out of 10 private label knife problems get expensive. We can regrind a blade on the water-cooled belt, but a wrong handle mold, rivets sitting 0.4 mm off-center, or wood scales that swell after packing can spoil the batch. Your chef knife spec should lock down the tang, handle material, fastening method, finishing, and balance point before we run the first 20 pcs pilot.

Common handle options include POM, ABS, PP, pakkawood, G10, micarta, stainless hollow handle, and natural wood. For steady B2B programs, POM and pakkawood still make sense because buyers know the feel and the cost works. G10 and micarta give a better shelf impression and resist moisture well, but the grinding line needs tighter edge rounding, usually checked at 0.2-0.3 mm around the scale. Natural wood photographs well, then moves with humidity; for Europe and North America, accept color variation, possible extra oiling, and one buyer pushing back because 12 handles in a carton did not match the showroom sample.

A full tang chef knife normally costs more than a welded bolster or hollow handle structure, but it sends a stronger quality signal. If you specify full tang, define the tang exposure, rivet material, rivet diameter, handle scale thickness, and flushness tolerance. Raised rivets and sharp handle edges look like small defects at AQL 2.5, then turn into one-star retail reviews. QC pulled a sample last month with a 0.6 mm rivet lip, and the buyer flagged it before we even discussed cartons.

Balance is the wrong place to write “comfortable” on a PO. A heavy Western-style chef knife may balance near the bolster or slightly forward. A lighter gyuto-style knife may balance 10-25 mm forward of the handle. If you are copying a benchmark sample, send the actual sample and ask the factory to measure weight and balance point on a digital scale and balance jig. For an 8 inch chef knife, a typical weight range is 165-240 g depending on construction.

For custom handle colors, molded logos, or new handle shapes, the chef knife MOQ often moves from 300-500 pcs to 1,000-2,000 pcs per SKU because of tooling, color matching, and setup waste. We run color chips against the approved Pantone card, but the first injection trial can still burn 80-120 pcs before the shade settles. If you are testing a new brand, start with standard handle tooling. Custom molds before repeat sell-through is proven can go sideways fast.

MOQ, Pricing And Lead Time Reality

MOQ is not a factory penalty. It is the break-even point where steel sheet buying, CNC handle setup, color box printing, AQL 2.5 inspection, and export documents stop fighting each other. We run laser logos on an existing chef knife at one setup level; a new blade profile, custom handle mold, retail box, and molded insert sit in another cost bucket. The buyer often asks, “Can we test 100 pcs first?” For full private label, that is the wrong question to ask because the grinding line still needs jigs set, logo artwork checked at 0.2 mm tolerance, and cartons booked.

For TANGFORGE private label chef knife projects in China, workable MOQ starts at 300 pcs per model for laser logo on existing designs, 500 pcs for custom color handle or modified packaging, and 1,000-2,000 pcs for new tooling. Damascus chef knives may require 300-500 pcs depending on the billet and pattern; QC pulled one 67-layer sample last month because the pattern looked weak after acid washing. Mixed-SKU orders can share packaging film or handle material in some cases, but do not assume 100 pcs per SKU will hold stable factory pricing. The math doesn't work.

Indicative FOB pricing from Yangjiang, China is:

For lead time, we quote 7-15 days for sample adjustment, 25-45 days for mass production after deposit and approved pre-production sample, and 10-20 extra days when new molds or special packaging are involved. Real example: a laser logo sample can leave in 12 days, while a pakkawood handle color correction often takes 18 days because the buyer flags the shade under a D65 light box. Before Q4, add at least 10 days of buffer. If you need DDP delivery, FNSKU labeling, carton drop tests, or Amazon prep, put it into the PI before approval; we have seen this go sideways when a PO typo changed “FNSKU” to “SKU” and the warehouse refused the cartons.

Packaging And Private Label Details

Private label work is not done when the logo is on the blade. Packaging, barcode, care card, carton mark, and pallet spec are part of the sellable unit. We have had QC pull 32 packed samples where the knife looked clean, but the FNSKU was one digit off and the 2.0 mm tip had already punched the paper sleeve. Receiving will reject that carton.

For retail and e-commerce, write the packaging structure in the PO, not only in WeChat chat history. Common builds are blade guard with color box, magnetic gift box with EVA insert, kraft box with sleeve, blister card, or roll bag for a 3-piece set. For Amazon or DTC shipping, we run a packed-drop check from 80 cm and a simple box crush check before signing off. A chef knife tip becomes a safety complaint fast if the insert is 1 mm too loose.

Your artwork files should show brand logo, steel marking, country of origin, barcode, SKU code, importer address, warning text, and care instructions. For EU sales, check language by country; one buyer flagged a German care card because “hand wash only” was left in English. For US sales, confirm any Prop 65 warning decision with your compliance adviser. If you sell into foodservice distribution, premium packaging is often the wrong question to ask because the math sits in unit cost and repeat replacement.

Logo method changes cost and risk. Laser engraving is flexible and usually has low setup cost; we can run it after final edge inspection without touching the carton line. Silk screen printing on packaging works at 500 pcs and above. Hot stamping, embossing, magnetic boxes, and custom inserts look premium, but they push MOQ up and bring defects such as glue marks, color drift against the Pantone chip, and crushed corners after 18 kg master cartons are stacked.

Ask the factory for a packaging dieline and one packed sample before mass printing. We have seen buyers approve a beautiful box render, then discover the real blade guard shifts 6 mm inside the EVA insert. That is not a design problem. It is a spec problem, and we have seen this go sideways when the packed sample is treated like decoration instead of a functional sample.

QC Risks To Control Early

Chef knives usually fail in the same places. Name those risks on the spec sheet before we run steel through the grinding line, then inspect against that list. Arguing about “premium quality” at final inspection is the wrong question to ask; last month QC pulled 80 pcs from sealed cartons and 11 needed rework, which cost 12 days instead of the 3 days we had planned.

The repeat offenders are edge inconsistency, blade warp over 1.5 mm, wrong HRC, handle gaps, loose rivets, uneven satin finish, logo drift over 0.8 mm, rust dots, bent tips, and crushed color boxes. For full tang knives, check tang flushness with a 0.10 mm feeler gauge and compare left-right handle symmetry at the rivet line. For Damascus knives, check pattern matching, lamination lines, and over-etching near the edge; we have seen buyers flag a 2 mm pale strip above the bevel even when the knife cut fine.

Use an inspection plan with defect classifications. AQL 2.5 for major defects and AQL 4.0 for minor defects is a practical starting point for most 1,000-10,000 pcs B2B chef knife orders. Critical defects stay zero tolerance: exposed broken tips, unsafe loose handles, cracked blades, severe rust, wrong logo, wrong SKU, or contamination inside packaging. For higher-price retail programs, tighten the standard if needed, but the math doesn’t work unless the buyer accepts more inspection time and rework cost; one U.S. PO even had the SKU typed as 8 inch while the artwork said 203 mm.

Production control should cover incoming material checks, heat treatment hardness testing, in-process grinding checks, handle assembly checks, and final packed-goods inspection. For a 5,000 pcs order, do not rely only on 20 final samples pulled from finished cartons. Check while the job is still moving. We run HRC testing after heat treatment, caliper checks after surface grinding, and rivet pull checks before polishing, because a 0.3 mm handle gap is cheap to fix before packing and painful after 420 cartons are taped.

Ask for measurement reports on blade length, thickness, weight, HRC, and packaging dimensions. For HRC, test several blades from different heat treatment batches, not just one clean sample from the supervisor’s desk. For sharpness, agree on a method buyers and factory QC can repeat: paper cut, tomato slice, edge visual check, or CATRA test for formal programs. At TANGFORGE in Yangjiang, Zhejiang export projects, we keep signed golden samples, approved drawings, and final inspection photos in one order file, so when the buyer flags a 1 mm logo shift, we compare it against the approved sample instead of arguing from memory.
