Bronze
Bronze is a copper-alloy family that includes distinct phosphor, aluminium and silicon bronze systems. EDC sources may identify only bronze; that broad label does not establish a grade, composition or surface treatment.

From a bronze scabbard and a bronze spinner edition to phosphor-bronze combinations
The current GB/T 5231-2022 covers designations and chemical compositions of wrought copper and copper alloys; industry data also separates phosphor bronze, aluminium bronze and silicon bronze into different families. When a product source says only “bronze,” a specific formulation or grade cannot be supplied from appearance.
This page uses “phosphor bronze” only where the original source does. Photographs establish the product, version and finish; gold, reddish-brown, silvery or dark tones do not by themselves distinguish bronze from brass, copper or baitong.
Wanwu Lezhi EDC’s Tai'a Jian: the source specifies a bronze scabbard and a titanium-alloy sword.
Bronze is neither a colour nor one fixed grade
Brass, copper, baitong and bronze cannot be reassigned from photographic tone. Finish, lighting and oxidation can all alter visible appearance; a photograph shows how one finished product presents.
Tai'a Jian: bronze is used for the scabbard
Wanwu Lezhi EDC uses bronze for the Tai'a Jian scabbard and titanium alloy for the sword. The complete configuration is listed at 98 g.
The bronze component is first sandblasted, then antiqued, and finally stonewashed, ground and polished. The titanium-alloy sword and black insert have their own finishes; 98 g is neither the scabbard alone nor a density figure for bronze.
Nun: two finishes for one bronze edition
The fine-polished finish of the bronze-edition Nun; the source separately lists a sandblasted, antiqued finish.
SilentGarden’s bronze-edition Nun entry lists fine polishing and sandblasting with antiquing, each with an adjacent product photograph. The images show the same form under two different finishes.
The source prints the weight as “70±g” but provides no value after the ± sign. It is therefore treated here only as nominally about 70 g, without inventing a tolerance. Structural figures such as the 49 mm spin diameter belong to the Nun product, not to bronze as a material.
Siren: bronze is one part of tri-colour mokume
Siren tri-colour mokume: the source explicitly lists bronze, baitong (source-termed “white copper”) and brass.
Siren’s tri-colour mokume is explicitly composed of bronze, baitong (source-termed “white copper”) and brass. The brand says a shallow acid wash gives this version a subtle ice-crystal effect and that it will gradually oxidize and develop a patina over time.
The complete piece cannot be reduced to bronze, nor can each gold or brown band be assigned to one of the three metals by eye. The source prints “44g+/-” without a numeric tolerance, so this page reports only a nominal weight of about 44 g.
Zhendang 2.0: black PEEK plus phosphor bronze
The source lists Zhendang 2.0 as black PEEK plus phosphor bronze; it does not label each visible component.
The Guangzhou EDC Day exhibition guide lists Zhendang 2.0 as black PEEK plus phosphor bronze. The photograph sits with that entry and establishes the product and its two-material configuration.
The source does not label each photographed component or state a phosphor-bronze grade, composition or heat treatment. The caption therefore records only the combination, without assigning parts by colour.
Xiongzhua · Jilong Waiguge: phosphor bronze in the handle combination
Xiongzhua · Jilong Waiguge: alongside its M390 blade, the handle material is listed as titanium alloy plus phosphor bronze.
The same exhibition guide also lists Xiongzhua · Jilong Waiguge: the blade is M390, while the handle material is titanium alloy plus phosphor bronze. Here “phosphor bronze” is more specific than the broader term “bronze.”
The source still does not label individual handle components. The photograph confirms this tool and its handle-material combination; silvery or copper-coloured appearance cannot assign each piece to titanium alloy or phosphor bronze.
How to read the source: component, finish, then figures
First establish whether bronze describes the body, shell, scabbard, a handle-material combination or one constituent of mokume. Then check whether the source gives a more specific name such as phosphor bronze or aluminium bronze. Finally, tie weight, dimensions and finish to the stated version.
Polishing, sandblasting with antiquing, stonewashing or shallow acid washing changes the visible surface. Brand statements about feel, wear or patina belong to the named product and treatment conditions.

Examples in detail
Wanwu Lezhi EDC · Tai'a Jian
Bronze scabbard and titanium-alloy sword
The complete configuration is listed at 98 g; the bronze sequence is sandblasting, antiquing, then stonewashing, grinding and polishing.
Materials and finishes are assigned separately to the scabbard, sword and insert, so one material name cannot describe the entire piece.
SilentGarden · Nun
Polished and sandblasted-antiqued finishes for the bronze edition
The source lists two finishes for the same bronze-edition form and prints the weight as 70±g.
Because no value follows ±, this page treats it only as nominally about 70 g.
The same bronze-edition Nun with a sandblasted, antiqued finish; tone alone does not establish a different grade.
SilentGarden · Siren
Tri-colour mokume of bronze, baitong and brass
Bronze is one of three constituents; the shallow acid wash and later oxidation and patina are the brand’s description of this version.
The source prints the weight as 44g+/-, without a numeric tolerance.
Phosphor-bronze combinations
A black-PEEK configuration and a titanium-alloy handle combination
Zhendang 2.0 is listed as black PEEK plus phosphor bronze; the Xiongzhua · Jilong Waiguge handle is listed as titanium alloy plus phosphor bronze.
The single exhibition article does not support assigning individual subcomponents by colour.
Common confusions
From Bronze is neither a colour nor one fixed grade
Copper-alloy references list phosphor bronze, aluminium bronze and silicon bronze separately. When an EDC source says only “bronze,” this page retains that family-level term without supplying tin content, aluminium content or a specific grade.
