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
Not every angler wants the lightest possible blade. Some prefer a knife with a bit of heft and a grippier build, especially when hands are wet from a full day on the water. The Cuda 18870 leans into that preference with a silicone build weighing 7 ounces, listed at a 9 inch length with a 6 inch size spec, in a blue finish.
At $24.12 it sits close to the Kershaw 1249X ($28.46) and the Kershaw 1247X ($25.71), above the Rapala BP136SH ($17.5) and Kershaw 1259X ($20.51), and well under the Kershaw 1242GEX ($44.76). At 7 ounces it is more than double the weight of the CUDA 18832's 2.24 ounces and twice the 3.5 ounce weight of the Kershaw 1259X and 1242GEX, making it the heaviest fillet knife in this set.
A 4.5 star rating across 328 reviews is the second largest review count in this comparison, behind only the Kershaw 1259X's 1,500 reviews, and well ahead of the 200 to 264 review range held by most of the other fillet knives here. Bought last month is listed at 0+, in line with most of the set aside from the Rapala 126SP's 100+ and the Kershaw 1259X's 50+.

Performance notes
At 7 ounces the Cuda 18870 is meaningfully heavier than the rest of this comparison, more than double the CUDA 18832's 2.24 ounces and twice the 3.5 ounce weight shared by the Kershaw 1259X and 1242GEX. Extra weight in a fillet knife typically shifts the feel toward a more deliberate, controlled stroke rather than a fast, light touch, and a silicone build often means a grippier surface than the steel or stainless steel builds used elsewhere in this comparison, which matters when hands get slippery from fish and water. The listed specs show a 9 inch length alongside a 6 inch size, a detail worth double checking against the product listing before ordering, since the two figures do not match the straightforward single blade length given for the other knives in this set. The blue finish and silicone material set it apart from the black steel, silver synthetic, and stainless steel options among the other fillet knives compared here.
What buyers say
A 4.5 star rating across 328 reviews gives the Cuda 18870 one of the larger review bases in this comparison, second only to the Kershaw 1259X's 1,500 and well ahead of the 200 to 264 range held by the Rapala BP136SH, Kershaw 1247X, and Kershaw 1242GEX. A high rating paired with a larger review count generally signals a more consistently proven track record than knives with similar ratings but far fewer reviews, such as the Kershaw 1249X's 142. Bought last month is listed at 0+, the same figure shown for most of the fillet knives in this set aside from the Rapala 126SP's 100+ and the Kershaw 1259X's 50+, suggesting steady historical satisfaction without standing out on current purchase volume.

Frequently asked questions
How much does the Cuda 18870 weigh compared to other fillet knives?
At 7 ounces it is the heaviest fillet knife in this comparison, more than double the CUDA 18832's 2.24 ounces and twice the 3.5 ounce weight of the Kershaw 1259X and 1242GEX. The added weight comes from its silicone build, which trades light weight for a grippier feel in hand.
Why do the length and size specs look different for this knife?
The listing shows a 9 inch length alongside a 6 inch size spec, two different figures rather than a single matching blade length. It is worth checking the product listing directly for exact blade dimensions before ordering, since other fillet knives in this comparison list one consistent length figure.
How does the review volume compare to other Cuda and Kershaw knives?
With 328 reviews, the 18870 has the second largest review base in this comparison, trailing only the Kershaw 1259X's 1,500. That puts it well ahead of the CUDA 18832's 202 reviews and the Kershaw 1247X's 200 reviews at a similar 4.5 star rating.
