Rapala Fish 'n Fillet Knife 6 in: problems, parts and running costs

Checked: 2026-10-19

Summary

The Rapala Fish ’n Fillet 6 in is a budget fixed-blade fillet knife: a 6-inch, full-tang European stainless blade in a birch handle, sold with a leather Laplander sheath and a single-stage sharpener. The recurring problems are rust when the blade is not rinsed and dried, a birch handle that gets slick with fish slime or wet hands, and an edge that needs touch-ups after a handful of large fish. It has no consumables and no battery, so the yearly running cost is effectively nothing beyond sharpening, and it is a strong buy at the $25–33 tier Rapala’s own store lists, weaker above $55.

Common problems and fixes

Rust if not dried — owners warn the blade can “rust at the drop of a hat” and advise rinsing and drying it well after use, especially after saltwater; the UK tester gives the same advice. Fix: rinse and dry after every use. No warranty terms are published, so warranty coverage is unknown. [10][6]
Birch handle gets slick — Outdoor Life’s 2026 field test names handle slickness in fish slime as its only criticism, and the UK tester reports the same with wet or oily hands; a rubber-handled competitor grips better on slimy fish. Fix: wipe your grip and the handle between fish, or choose a rubber-grip knife. [1][6][9]
Edge needs frequent touch-up — the UK tester needed a touch-up after five large fish, and Outdoor Life’s general guidance is a honing-rod touch-up every few fish. Fix: hone regularly and re-edge at a consistent angle on both sides; the Scandi grind is easy to sharpen. [6][1]
Leather sheath is not waterproof — it can stiffen if damp. Fix: let it air dry rather than storing the knife wet in it. [6]
Blade steel is the weak point for heavy use — a 2017 specialist guide advises against it for weekly heavy use over blade-steel quality, and some owners call the knives cheaply made. No fix; treat it as a light-duty knife. [7][10]

Parts and consumables

No replaceable parts or consumables are reported. [2][1]

Yearly running cost

Effectively $0 a year. The knife is manual — no battery, no electricity, no subscription — and the only upkeep is sharpening with the included sharpener, so a typical owner spends nothing per year on parts or consumables. [2][6]

When it is a good buy

At $25–33 — Rapala’s own US store lists the Fish ’n Fillet line from $25.49 (category page) and the same-construction Firetiger 6 inch variant with sharpener at $32.99, read October 2026; at this tier the included leather sheath and sharpener are unusual, and the only real weakness is handle slickness in slime. [4][3]
At $33–55 — fair value only if the included sheath and sharpener matter to you; the same tests’ higher-priced picks offer rubberized wet-grip handles the Fish ’n Fillet lacks. [1][6]
Above $55 — weak value; the product page’s own $55.49 figure appears to be a compare-at or configuration price rather than a street price. [2]

Named alternatives:

Berkley fillet knife — the rubber-handled comparison owners make; the better choice when you fillet slimy fish such as catfish and want marginally better edge retention. [9][11]
Larger Fish ’n Fillet sizes (7-1/2, 9 inch) — the better choice when you regularly handle fish over 3 kg, since the 6-inch blade is short for them. [2][6]
