NDA, IP and tooling ownership when you outsource EDC manufacturing

Knife and pen designs get copied. Sometimes by a competitor with a photo, sometimes by the factory that made them. The second is rarer than forum folklore suggests but it does happen, and a few sentences agreed before you send a file remove most of the exposure.

This is not legal advice. It is what we see work in practice at EDC scale.

What an NDA does and does not do

Does: create a contractual obligation not to disclose your design, and — critically — not to manufacture it for anyone else. It gives you something to point at, and the act of signing filters out anyone who was never going to take it seriously.

Does not: prevent copying by someone who never signed it. Nor does it protect the idea of a frame-lock titanium folder. It protects your specific design and the information you shared.

Sign it before the file is sent, not after the quote comes back. Once a STEP file is in someone’s inbox it is in their inbox.

The clause most NDAs miss

A standard mutual NDA covers disclosure. For manufacturing you want an explicit non-manufacture clause: the supplier will not produce the part, or a substantially similar part, for any third party, including itself.

Without that, a supplier can argue it disclosed nothing while running your design as a house product. Add the clause; it is one sentence and nobody reasonable objects.

Tooling, fixtures and programs

Here is the question almost nobody asks and everybody should: who owns the workholding and the CAM program your first order paid for?

Three positions exist in practice:

Shop owns it. The default when nothing is agreed. The setup cost was amortised into your price, and the fixture stays. Moving to another supplier means paying setup again.

You own it. Possible if you pay a separate, stated tooling charge. The fixture and program are yours and can be transferred. Expect to pay meaningfully more up front.

Shop owns it, you have transfer rights. The middle ground, and usually the sensible one for EDC. The shop keeps and maintains it; you have the contractual right to have it transferred to another supplier on request, possibly for a stated fee.

Whichever you choose, agree it in writing before the first order, because it decides how expensive it is to leave.

For formed parts with a real die — pocket clips at volume, stamped hardware — this matters much more, because die cost is substantial and it is the thing that locks you in.

Photographs

Many shops post customer work on their website and social media. For an unreleased EDC design that is a genuine problem, and it is a common accidental leak.

One line: “Supplier shall not photograph, publish or display parts produced under this agreement without written permission.” Say it explicitly, because a shop that thinks it is helping with marketing will not otherwise ask.

We do not publish photos of parts we route, which is also why this site has no product photography.

Sub-suppliers

Your part probably touches a heat treater, an anodizer or a PVD house. Your NDA with the machine shop does not automatically bind them.

Ask that the supplier flow down the confidentiality obligations to sub-suppliers, and ask which processes are outsourced. That second question is useful regardless of IP, because it tells you where the schedule risk lives.

Practical layering

For a small EDC brand, proportionate protection looks like:

1. NDA with a non-manufacture clause, signed before files are sent
2. A written tooling ownership position in the first PO
3. A no-photography clause
4. Flow-down to sub-suppliers
5. Registered design or design patent in your main market if the product justifies it — this is the only item on the list that gives you rights against a stranger

Items one to four cost nothing but the time to write them. Item five costs money and is worth it for a flagship product, rarely for a variant.

Before you send anything

Ask for the NDA. A supplier that hesitates has told you something useful for free.

Ask us for one before you upload a drawing — we sign before we open the file, and any shop that sees it signs too. Related: how to write an RFQ a shop can quote.

What a workable NDA contains

You do not need a long document. For EDC manufacturing, the clauses that do the work are:

Definition of confidential information — broad enough to cover CAD files, drawings, specifications, prices and the existence of the relationship.

Non-disclosure — the standard obligation not to share it.

Non-manufacture — the clause discussed above, and the one most templates omit. The supplier will not produce the part, or anything substantially similar, for any third party or for itself.

Flow-down — the supplier must bind its sub-suppliers to equivalent terms.

No publication — no photographs, no website, no social media, no trade show display without written permission.

Return or destruction — on request or at the end of the relationship, files are returned or destroyed.

Term — how long it lasts. Five years is common; perpetual for genuinely proprietary process information.

Governing law and jurisdiction — pick something both parties can realistically use. Singapore is a common neutral choice for Asia-based manufacturing relationships.

That is a two-page document. Have a lawyer draft one once and reuse it.

Enforcement realism

An NDA in a cross-border manufacturing relationship is worth having and is rarely worth litigating for a small brand. The cost of pursuing a breach in a foreign court will exceed the value of most EDC production runs.

So treat it as doing three jobs:

1. Deterrence. A supplier that signs something specific is more careful than one that signed nothing.
2. Filtering. How a supplier responds to an NDA request is information. Reluctance is a signal.
3. Clarity. Most breaches are not malicious. They are a shop posting a photo without thinking. A written no-publication clause prevents that entirely.

Protection that actually scales comes from the relationship and from not concentrating everything in one place, not from the document.

Splitting the work

A practical strategy that costs nothing: no single supplier holds your whole product.

If your scales come from one shop, your clips from another and your hardware from a third, no single party can assemble and sell your knife. For a brand with a distinctive product this is meaningful protection, and it has a supply chain resilience benefit too — see Vietnam vs China sourcing.

The cost is coordination. Whether it is worth it depends on how copyable and how valuable the design is.

Registered rights, briefly

The only protection that works against someone you have no contract with:

Registered design / design patent protects the appearance. Relatively cheap, relatively fast, and well suited to EDC where the look is the product. File before public disclosure — most jurisdictions have strict novelty requirements, and posting a render on social media can destroy your ability to register.

Utility patent protects a mechanism. Expensive, slow, and worth it only for a genuinely novel mechanism.

Trade mark protects your brand name and logo. Cheap relative to the others, and often the most practically useful, because a counterfeit carrying your mark is straightforwardly actionable in a way a similar-looking knife is not.

Register in the market where you sell, which for most EDC brands is the US and possibly the EU. Registering in the country of manufacture is a separate and sometimes worthwhile step.

Timing

The sequence that keeps your options open:

1. Design
2. File registered design if the product justifies it
3. NDA with supplier
4. Send files
5. Prototype
6. Public announcement

Announcing before filing is the most common and most expensive mistake, because it is irreversible.

FAQ

Will a supplier actually sign my NDA? Most will, without much negotiation. Some will want to use their own; reading theirs and adding a non-manufacture clause is usually acceptable to both sides.

Should the NDA be mutual? Usually yes. The supplier has process information it would rather you did not share either, and a mutual agreement is easier to get signed.

What if the supplier wants to show my part to a potential customer? That is what the no-publication clause is for. If you are happy for them to, give written permission for that specific instance. Do not leave it to a general understanding.

Who owns improvements the shop suggests? Worth a clause. A shop that proposes a design change that makes the part cheaper has contributed something. The usual position is that you own the design including improvements, and the shop retains its general manufacturing know-how. Say it rather than leaving it open.

Should I be worried about a shop copying my design? Less than forum discussions suggest, and not zero. An established export shop has more to lose than to gain. A shop taking its first international order is a less known quantity — which is one more reason to start small.

Can you sign before I send anything? Yes. Ask for the NDA first and we will sign before the file is opened, and any shop that sees it signs too. Start there.
