Custom EDC parts, by part type
Knife scales, liners, pivots, pocket clips, flashlight bodies, pen barrels, beads and pocket tools. For each one: the materials makers usually choose, the features that decide whether it works, and the finishes that go with it.
Parts, materials and the features that matter
Common choices, not rules. Your drawing decides, and the quote states what the shop will hold on each critical feature.
| Part | Common materials | Critical features | Typical finishes |
|---|---|---|---|
| Knife scales | Titanium Gr5, G10, carbon fibre, Micarta, 6061 / 7075 | Pivot and standoff hole positions, thickness, contour | Stonewash, bead-blast, anodize, textured |
| Frame-lock liners | Titanium Gr5, hardened steel insert | Lockbar geometry, lock face angle, detent position | Stonewash, bead-blast |
| Pivots, standoffs, backspacers | 416 stainless, titanium Gr5, bronze washers | Diameter, length, thread class, concentricity | Polished, PVD, bead-blast |
| Pocket clips | Titanium Gr5, 17-4 PH, spring steel | Thickness, bend, screw hole spacing, retention | Stonewash, anodize, PVD |
| Flashlight bodies and heads | 6061-T6, titanium, copper, brass | Thread pairs, O-ring grooves, bore for driver, wall thickness | Type III anodize, stonewash, bare |
| Pen barrels and bolt actions | Titanium Gr5 / Gr9, brass, copper, zirconium | Refill bore, cam path, thread fit, wall thickness | Stonewash, bead-blast, anodize, patina |
| Lanyard beads | Brass, copper, titanium, zirconium | Through-hole size, edge break, pattern depth | Polished, tumbled, anodize |
| Pry bars and keychain tools | Titanium Gr5, hardened stainless, tool steel | Tip geometry, thickness, hardness | Stonewash, bead-blast, PVD |
| Fidget sliders and spinners | Titanium, stainless, brass, copper, Zr | Slide fit, magnet pockets, detent feel, tolerance stack | Mirror, stonewash, bead-blast |

Knife scales, liners, pivots and clips
Scales and frames
Scales are milled from plate in two setups, or on a 4- or 5-axis machine when the contour wraps the edge. Hole positions for the pivot, standoffs and clip decide whether the knife assembles and closes centred, so those carry the tight callouts while cosmetic faces stay general. Tolerances for knife scales
Frame-lock liners
The lockbar is the part that has to be right. Lock face angle, bar thickness and detent ball position set lock-up and action feel. Many makers add a hardened steel insert where the lockbar meets the blade tang.
Pivots and hardware
Pivots, standoffs and backspacers are small turned parts, usually from 416 stainless or titanium on a Swiss-type lathe. Concentricity and thread class matter more than any single diameter. Washers in phosphor bronze, PTFE or PEEK set the action.
Pocket clips
A clip has to flex without taking a set. Material, thickness and bend geometry decide retention, so state them all, plus the screw spacing it must match. Clip design and spring temper
Flashlights, pens, beads and pocket tools
Flashlight bodies
Bodies, heads and tail caps are turned from bar, with threads cut on the same setup so heads swap without binding. 6061-T6 with Type III anodize is the default; titanium and copper need careful thread pairing to avoid galling. Threads that do not gall
Pens
Barrels, tips and bolt-action bodies, mostly titanium or brass. Refill bore, thread fit and the cam path on bolt actions are the features that decide whether the pen works. Titanium pen machining
Lanyard beads
Small turned or milled parts, cheap to tool and a common first order for a new brand. Hole size and edge breaks matter for paracord. Lanyard beads and small turned parts
Pry bars, keychain tools and fidget hardware
Pry bars and keychain tools are milled from plate, often in titanium Grade 5. Fidget sliders and spinners are about feel: slide fit, magnet pocket depth and the tolerance stack across parts.
What to send for each part
- A STEP file plus a PDF drawing with the critical features dimensioned.
- Material grade and temper, and whether a substitute is acceptable.
- Finish by name, with a reference photo or sample, and whether dimensions apply before or after finish.
- Quantity for the first run and the expected size of later drops.
- Marking: logo, serial numbers and where they go.

Questions about custom EDC parts
- What is the minimum quantity for custom EDC parts?
- One piece for a prototype. Small batches of 10 to 500 pieces are the normal range for the shops in the network, and many first drops start at 25 to 50 units to prove fit and finish.
- Can one shop make every part of my knife or flashlight?
- Often, but not always. A shop strong on milled titanium scales may not run Swiss-turned pivots or hard anodize in-house. Tell us on the RFQ which parts belong together and we shortlist shops that can cover the set, or flag the parts that need a second shop.
- Can you make blades?
- Blade work depends on the steel and the heat treatment, and it is quoted case by case. Many makers send blades to a specialist and use the network for scales, liners, clips and hardware. Send the drawing with the steel and hardness you need.
- How do I keep my design confidential?
- Ask for an NDA on the RFQ. It is signed before the file is opened, by us and by any shop that sees it, and your file only goes to shops you approve.
Run a CNC shop? Join the network
We are a sourcing desk, not a factory. Buyers send us drawings for EDC parts: knife scales, pen bodies, flashlight hosts. We route each one to the shops that genuinely fit. If you run precision CNC in Vietnam and small batches are a business you want rather than a favour you tolerate, join the network.
No listing fee. You receive RFQs matched to your machines and materials, you quote the buyer through us, and you keep the customer relationship once the first order ships.
Send a drawing. Get matched with a supplier.
One RFQ, routed to the shops in the network that actually run your material, your finish and your batch size.
