Anglers who want a complete slip-resistant fillet knife kit rather than a bare blade, and buyers who weigh both a high star rating and strong recent sales before choosing.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
Fish scales on the deck and a slick handle underfoot are the two things that make a fillet knife feel dangerous rather than useful, and the KastKing KTACPCKNF-KNFSP5 leans on a slip-resistant build to answer both. At $49.79, it is priced as a full kit rather than a single blade.
The listed 9-inch size lines up with other well-reviewed knives in this comparison, while an overall length figure of 16.61 inches and a weight of 2.2 pounds point to a kit that bundles more than just the blade itself, likely a sheath or case alongside it. That kit format hasn't hurt its reception: 537 reviews average out to 4.7 stars, the highest rating of any fillet knife covered here, and 400+ units bought last month ties it with the Sidomma set for the strongest recent demand in this lineup.
Against the field, the KastKing kit beats the Kershaw 1259X's 4.6-star average while running at roughly double the Rapala BP136SH's price. For anglers deciding between a bare blade and a slip-resistant kit, the 4.7-star rating paired with 400+ recent buyers makes a strong case that this kit format is working for a lot of people.
Pros
- 4.7-star rating across 537 reviews, the highest average of any fillet knife in this comparison
- 400+ units bought last month, tied for the strongest demand figure here
- Slip-resistant build addresses one of the most common complaints with wet-handle knives
- 9-inch blade size matches other well-reviewed knives like the Kershaw 1259X
- Kit format with a 2.2-pound total weight suggests included extras beyond a bare blade
Cons
- At $49.79, it costs roughly $30 more than the similarly sized 9-inch Kershaw 1259X
- The 16.61-inch and 2.2-pound figures make it unclear exactly what is included in the kit
- Color is listed only as 'Fillet Knives Kit', giving no visual detail on the actual blade finish
- One piece count means no backup blade if this one is lost or damaged

Performance notes
A slip-resistant build targets the exact moment a fillet knife becomes risky to use, when hands are wet and covered in fish oil and a smooth handle starts to twist mid-cut. The 9-inch size places this blade in the same length range as the Kershaw 1259X, long enough for full-length fillet strokes on mid-to-large fish. The overall 16.61-inch length and 2.2-pound weight are considerably larger than a single blade would weigh on its own, which points to this being a packaged kit rather than a bare knife, likely including a sheath, case, or additional tool alongside the blade. That kit format adds bulk to a tackle bag compared to a single lightweight blade like the 2.4-ounce Rapala 126SP, but it also means fewer loose pieces to track down mid-trip.
What buyers say
A 4.7-star average is the highest rating of any fillet knife in this comparison, and with 537 reviews behind it, that is not a thin or easily skewed sample. Pairing that rating with 400+ units bought last month, tied with the Sidomma set for the top demand figure here, suggests this kit is both well-liked and actively selling rather than resting on old reviews. That combination of top-tier rating and strong recent volume is the strongest overall pattern in this set of alternatives, ahead of pricier and cheaper options alike.

Frequently asked questions
What is included in the KastKing KTACPCKNF-KNFSP5 kit?
The listing specifies a 9-inch blade size along with an overall length of 16.61 inches and a weight of 2.2 pounds, figures that suggest the kit includes more than a bare blade, such as a sheath or case. The exact contents beyond the blade are not fully broken out in the specs.
How does the KastKing KNFSP5 rating compare to other fillet knives?
It holds a 4.7-star average across 537 reviews, the highest rating among the fillet knives in this comparison. That edges out the 4.6-star Kershaw 1259X and KNINE YD2208, though all three sit fairly close together on the overall rating scale.
Is the KastKing KNFSP5 a popular choice right now?
Yes. It shows 400+ units bought last month, tying the Sidomma 2 pcs set for the strongest recent demand among the fillet knives covered here. That volume alongside a 4.7-star rating points to sustained, current buyer interest rather than a fading older listing.
