Overview
The Cuda 18870 is a fillet knife with a blue silicone-wrapped handle, a 9 inch overall length, and roughly 7 ounces of heft. Sized for filleting panfish through mid-size fish at the dock or on the boat.
Silicone handles are used on fillet knives to stay grippy when wet, which matters more for this tool than blade steel alone since fish cleaning is a wet-hands job. The listing gives overall length and weight but no blade steel type.
- 9 inch overall length
- Blue silicone handle
- About 7 ounces
- Single knife, 1 count
Who it's for
Fits anglers who clean their own catch and want a knife that will not slip out of a wet or slimy hand. Less useful for anyone who wants a heavier duty knife for large fish or a knife that ships with a sheath, since none is listed.
Pros and cons
- Silicone grip for wet-hand control
- Light 7 ounce weight for easy handling
- Compact 9 inch overall size
- Blade steel type not specified
- No sheath mentioned in the listing
Performance notes
At about 7 ounces and 9 inches overall, the knife sits in the light, maneuverable range typical of fillet knives meant for quick cuts rather than heavy-duty butchering.
