Why brands put logos on blades
A Máquina de gravação a laser does that on hardened stainless and tool steels. It leaves crisp micro-detail and keeps the blade geometry intact. No die pressure. For a factory line or a small workshop, it’s a steady way to mark SKUs, batch codes, and brand logos without slowing the bench.
What “good” looks like on a kitchen knife
A good knife logo should be sharp, readable, and food-area friendly. On the flat of the blade, you usually aim for a smooth, non-grooved mark (often called “anneal” or “black mark”). On the ricasso, spine, or bolster, you can go deeper because those zones don’t touch food. Use the right process for the right place.
Mark types you can use on knives
| Mark Type | Where it shines | Surface feel | Typical look | Best practice notes |
|---|---|---|---|---|
| Black/annealed mark | Blade flats that might touch food | Smooth (no cutting of metal) | Deep gray/black contrast | Safer to clean; helps preserve corrosion resistance |
| Light etch | Branding on blade flats or near the heel | Slight texture | Dark contrast + slight frosting | Fast cycle; keep passes tight to avoid halo |
| Deep engrave | Ricasso, spine, bolster, ferrule | Noticeable groove | Strong shadow; tactile | Great for long-life logos; avoid food-contact zones |
| Micro-text/serial | Back of blade or tang | Barely perceptible | Hairline characters | Use fine hatch and small spot; fixture is key |
Here is a video showing how the BOGONG laser marking machine works on knife.
How shops run it
Clean first. Degrease the blade. Any oil will mess with contrast.
Fixture tight. Hold the blade so it doesn’t wiggle. A quick jig beats a thousand reworks.
Focus right. Auto-focus helps if your batch has mixed profiles. If not, shim it.
Test on scrap. Do one small swatch to lock contrast.
Mark, wipe, move on. After the pass, wipe and check—don’t overcook the steel.
Optional passivation. If you’re strict on hygiene claims, consider a post-step per your QA SOP.
This flow works on big production benches and tiny craft shops.
Pain points the shops may face
| Pain point from the floor | What’s likely happening | How operators fix it |
|---|---|---|
| Logo looks “washed out” | You’re out of focus or your hatch is too wide | “Bring it into focus and tighten the hatch.” Do a short test square. |
| Rainbow tint you didn’t want | Too much heat input on stainless | “Back off the dwell.” Reduce passes or speed up the scan a bit. |
| Speckled edges | Dirty blade or shaky fixture | “Clean it and clamp it.” Degrease + firmer jig = clean edge. |
| Ghosting/halo around letters | Overlapping passes too far | “Narrow your overlap.” Keep the fill lines closer. |
| Dark mark wiped lighter after alcohol | Only the oxide layer formed | “Give it one tidy pass more.” Short finishing pass after cleaning helps. |
| Deep groove traps dish gunk | You engraved on a food path | “Move it to the ricasso.” Keep deep cuts off the cutting zone. |
Where a Laser Engraving Machine pays back
Cleaner brand presentation on the blade equals higher shelf appeal. Buyers judge knives with their eyes first.
Traceability in plain sight. Serial, batch, and QA codes go right on steel, so your warehouse and warranty team stop guessing.
Lower consumables. No pads, ink, or acids to reorder. That’s less inventory and fewer “we ran out” calls.
Less downstream hassle. Smooth marks on food-touch areas make hygiene audits less painful.
BOGONG Laser builds for that routine. The brand lives in the details: stable galvos, easy focus, sensible UI, and service that doesn’t ghost you.
Picking gear sensibly
Stability. A steady galvo and rigid frame keep micro-text crisp.
Usability. Quick focus, clear preview, and file import that doesn’t break your brain.
Coverage. Enough field size for your longest chef’s knife, plus rotary support if you touch ferrules.
Dust and safety. A tidy enclosure and extraction keep your bench clean and your QA calm.
Service. You want real support from a Laser Engraving Machine Manufacturer.
Choose the right machine from BOGONG Laser
Máquina de marcação a laser de fibra de 30W — a compact Máquina de gravação a laser for metal logos and micro-text.
Gravador a laser de fibra 3D para metal — handles curved ferrules and uneven knife faces.
Handheld Fiber Laser Marking Machine — quick field marks on large parts, fixtures, or displays.
Knife-specific setup notes you’ll actually use
Logo placement. For deep grooves, pick the ricasso or spine. For the blade face, go for black/annealed.
Contrast tuning. If your black looks brownish, try a tighter line spacing and cleaner surface.
Edge guarding. Mask close to the bevel if you’re nervous about overspray-looking haze.
Batch consistency. Build a simple jig for your three common blade shapes. Save three job files with offsets.
Rinse workflow. Mark → wipe → quick rinse if required by your SOP → dry. Don’t leave moisture to sit.
Operator habit. Read the mark under the same light every time. Humans see contrast different under yellow vs. white light.
Evidence-backed statements
| Practical claim | Why it matters for kitchen knives | What to remember in production |
|---|---|---|
| Fiber lasers create clean, durable IDs on steel blades | Hardened steels and stainless respond well to this wavelength | Keep the focus true; small shifts hurt fine lines |
| Black/annealed marks suit blade flats | Smooth feel helps with cleaning and corrosion performance | Avoid heavy multi-pass cutting on food paths |
| Deep engraving lasts for ages | Great for spines, bolsters, and non-food zones | Use a firm fixture to prevent chatter |
| You can shift looks without changing machines | Same platform can do black mark, light etch, or deeper groove | Swap settings, not hardware; save recipes |
| Good fixturing beats guesswork | Stops ghosting and speckle at the root | Build jigs for your top blade families |
