Daiwa Samurai Braid Green Filler Spool
Lower concern; standard PE braided line unlikely to contain PFAS, but Daiwa makes no public disclosure.
Daiwa's Samurai Braid is a polyethylene braided fishing line with no known PFAS-related treatment. Standard PE fishing braid does not typically require water-resistant or stain-resistant coatings that would introduce PFAS.

The full breakdown
What it's made of and why it matters
Daiwa Samurai Braid is braided polyethylene (PE), a thermoplastic polymer extruded into fine filaments and woven together. PE is inert in water and resistant to UV degradation, making it stable in the aquatic environment it's designed for. Unlike monofilament nylon lines, braided PE does not absorb water significantly, so it maintains consistent tensile strength when wet. The green color is achieved via synthetic dye addition during extrusion, a standard practice in fishing line manufacturing.
The brand's record and disclosure
Daiwa (part of the Globeride group, a major Japanese fishing tackle manufacturer) maintains no public safety certifications, health disclosures, or third-party testing statements for its fishing lines. The company has no documented recalls specific to Samurai Braid or comparable braided PE lines. Daiwa's silence on PFAS and heavy metals in braided lines is typical across the fishing tackle industry, where such transparency is not standard practice. No controversies related to chemical hazards in Daiwa fishing lines are on record.
How it compares in its category
Braided PE lines are the safest category for users and aquatic environments compared to monofilament (which sheds microplastics over time) or fluorocarbon (which may leach fluorine compounds). Daiwa Samurai Braid occupies the mid-to-budget tier; it performs similarly to other major brands (Shimano, Berkley, PowerPro) with no documented quality or safety differentiators. PE braided lines as a class do not require special disposal protocols beyond landfill or incineration, though responsible anglers favor recycling programs where available.
If you buy it
Store the spool indoors away from direct sunlight to prevent UV fading, though PE is UV-stable. Inspect the line periodically for fraying or nicks, which weaken it; replace sections or the entire spool if damage is visible or tensile strength feels compromised (test by pulling against a known weight). Wash hands after handling if you have sensitive skin, as synthetic dyes can occasionally irritate. When retired, dispose responsibly; check whether local tackle shops or waste facilities accept fishing line for recycling rather than landfill.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Synthetic dyes and colorants (heavy metals in pigments)
Green dye used in this line is standard azo or reactive dye applied during PE extrusion. No testing data or recalls document heavy metal contamination in Daiwa braided lines; this hazard is not established for this product or brand.
Microplastic shedding during use
Braided PE lines can shed microscopic filaments during casting, knot tying, and wear, especially if frayed. The degree of shedding is not quantified for Samurai Braid specifically, but is inherent to braided PE as a material class and is lower than monofilament lines.
Colorant leaching into aquatic ecosystems
Extended water contact with dyed PE may result in minor pigment migration into the water column. This is not documented as a significant environmental or human health hazard for fishing lines, but is a theoretical consideration for anglers concerned with ecosystem impact.
Thermal degradation from heat storage or use
PE braided line does not degrade at the temperatures encountered in typical freshwater or saltwater fishing. No heat-related failure or chemical release is documented for Samurai Braid under normal use conditions.
Knot strength and breakage
This is a mechanical performance hazard, not a chemical one. Braided PE lines require proper knot technique; improper knots may slip or fail suddenly. This is a user-skill issue, not a product defect documented for Daiwa Samurai Braid.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
