The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other fishing gear and tackle we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
Grabbing a fillet knife off a boat rack before a day of cleaning fish is where a bundled sheath earns its keep, and the KastKing Fishing Knives-3 comes with exactly that. It pairs a Super Polymer Grip handle with a 7 inch blade, a 12.8 inch overall length, and a weight of 6.4 ounces, along with the included sheath for safe storage between uses.
At $25.64, it costs more than the Rapala 126SP's $10.49 and CUDA 18124's $18.97 but less than either BUBBA model. Its 4.6 star rating trails the 4.8 stars of both BUBBA knives and the CUDA's near-tie at 4.5, but it draws on 2,700 reviews, more than any other fillet knife in this comparison. Bought last month sits at 1,000+, five times the next closest figure of 200+ from the BUBBA BB1-9TF.
The pattern here is volume over peak rating. The KastKing Fishing Knives-3 does not claim the top star score, but no other knife in this comparison comes close to its review count or recent purchase activity, which points to broad, sustained popularity rather than a smaller enthusiast following.

Performance notes
A 7 inch blade paired with a 12.8 inch overall length gives the Fishing Knives-3 more working length than the Rapala 126SP's 6 inch blade, useful for longer, single-pass fillet strokes on mid-size fish. At 6.4 ounces, it carries noticeably more heft than the lightest knives in this comparison, which can add stability during the cut but also more fatigue over an extended cleaning session. The Super Polymer Grip is a handle material aimed at wet-hand traction, a similar goal to the Zytel and TPR combination used on other budget to mid-range knives here. The bundled sheath is a practical addition beyond the blade itself, since it protects the edge and adds a layer of safety when the knife is packed in a tackle bag rather than left loose.
What buyers say
With 2,700 reviews, the KastKing Fishing Knives-3 has the largest review base of any fillet knife in this comparison, more than five times the CUDA 18124's 194 reviews and well past the 1,500 to 1,700 range of the Kershaw and BUBBA BB1-9TF. Its 4.6 star average is solid though not the top score in the group. What stands out most is the 1,000+ bought last month figure, five times higher than the next closest number. That gap between rating and demand suggests a knife that wins on broad accessibility and value rather than chasing the absolute highest star average.

Frequently asked questions
How many reviews does the KastKing Fishing Knives-3 have?
It has 2,700 reviews, the largest review count among the fillet knives compared here. That is well above the 1,500 to 1,700 range of the Kershaw 1259X and BUBBA BB1-9TF, and far more than the CUDA 18124's 194 reviews, making it the most reviewed fillet knife in this comparison.
Does it come with a sheath?
Yes, the listed feature is Knife and Sheath, meaning the sheath ships along with the blade rather than being sold separately. This adds storage and edge protection that some other fillet knives in this comparison do not mention, a small added value at this price point.
Is the KastKing Fishing Knives-3 the best selling fillet knife in this comparison?
Based on the bought last month figures given, yes. It shows 1,000+ recent purchases, compared to 200+ for the next highest, the BUBBA BB1-9TF, making it the clear leader on recent demand among these fillet knives by a wide margin in this comparison.
