Available in 1000m spools in Black, White and Blue across line classes from 1.0# (6lb \/ 0.16mm) to 8.0# (35lb \/ 0.50mm). Suited to freshwater and saltwater spinning and overhead reel applications from light estuary fishing through to heavier surf and reef bait fishing.\u003c\/p\u003e\u003ch2\u003eJapan Material Nylon\u003c\/h2\u003e\u003cp\u003eThe BLADE is labelled “Japan Material” — the nylon polymer is sourced from Japan rather than from domestic Chinese-produced nylon. In the fishing line market, Japanese-sourced nylon polymer (from manufacturers such as Toray) is produced to tighter molecular consistency standards than standard-grade nylon, which has two practical effects on the finished line:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter consistency\u003c\/strong\u003e: tighter-spec nylon polymer produces a finished line with less diameter variation along its length; a line that maintains consistent diameter across 1000m has more consistent breaking strength along the spool and ties knots more uniformly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrength-to-diameter ratio\u003c\/strong\u003e: higher-grade nylon achieves the rated breaking strength at a smaller diameter than lower-grade nylon; a finer line at equivalent strength is less visible underwater and has lower water resistance, which improves casting distance and sink rate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNylon Monofilament Properties\u003c\/h2\u003e\u003cp\u003eNylon monofilament (mono) is the original fishing line material and remains widely used for specific applications where its properties are an advantage over braid and fluorocarbon:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStretch\u003c\/strong\u003e: nylon mono has significant stretch — typically 25–30% elongation before breaking; this stretch acts as a shock absorber during the initial strike, sudden runs and head shakes, reducing the likelihood of the hook pulling or the line breaking on an aggressive take; for bait fishing with exposed J-hooks where the fish has time to mouth and move, the stretch gives a margin before the hook load becomes critical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloating\u003c\/strong\u003e: nylon is slightly less dense than water and floats; this makes mono suitable for surface presentations (floating live baits, topwater rigs) and for surf fishing where a floating mainline stays on the surface through the wave zone rather than dragging on the bottom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnot performance\u003c\/strong\u003e: nylon’s surface and stretch properties make it one of the most forgiving materials for standard fishing knots; the Uni knot, Improved Clinch, Palomar and blood knot all perform reliably in nylon with correct execution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine memory\u003c\/strong\u003e: nylon mono retains the coil shape of the spool it is wound on, particularly in cold water; fresh line from a new spool will show coiling at the start of the session that reduces as the line absorbs water and warms; this is a characteristic of nylon rather than a defect and is managed by stretching the line before the first cast or by soaking the spool in warm water for 10 minutes before spooling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV degradation\u003c\/strong\u003e: nylon degrades with prolonged UV exposure and loses breaking strength over time; a 1000m spool used over multiple sessions should be checked periodically for surface texture change (rough, chalky or flaking surfaces indicate UV degradation) and replaced seasonally for critical applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e1000m Spool — Bulk Value and Backing\u003c\/h2\u003e\u003cp\u003eThe BLADE is supplied in 1000m spools. A 1000m spool serves two uses: it can fill two or more reels from a single spool at a lower cost per metre than a standard 150–300m retail spool; or the full 1000m can be used as backing and mainline on a larger overhead or surf reel that requires high line capacity. For spinning reels in the 2500–4000 class, 1000m of 6–12lb mono will overfill the reel — fill from the spool to within 2–3mm of the lip and retain the remaining line for the next refill when the top section wears.\u003c\/p\u003e\u003ch2\u003eLine Class and Diameter Table\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e1.0# \/ 6lb \/ 2.72kg \/
