Buying a fillet knife set is mostly about getting the right blade size, grip, and accessories without carrying more gear than you need. The Sidomma 2 pcs Fishing Fillet Knife Set combines two 6.5-inch high-carbon stainless steel knives with protective sheaths and a pocket sharpener, plus built-in features for scaling fish, opening bottles, and preparing bait. Its compact blade length makes the set practical for many freshwater catches and routine fish cleaning, although anglers who regularly process very large fish may prefer a longer fillet knife. This review explains where the Sidomma set works well, where its limits matter, and what you should check before buying.
Review note: This assessment is based on the current product listing, published specifications, feature documentation, and buyer-facing product information. It should not be read as a claim of hands-on laboratory testing.
Quick Verdict
Rating: 8.2/10, Recommended with caveats
Best For: Casual anglers, freshwater fishing, bait preparation, camping, and buyers who want two compact knives with sheaths and a sharpener.
Bottom Line: The Sidomma set gives you two 6.5-inch high-carbon stainless steel knives plus several useful fishing-oriented features in one compact package. Its main tradeoff is blade length, since buyers who clean large fish regularly may get better control from a longer, more specialized fillet knife.

What Is the Sidomma Fishing Fillet Knife Set?
The Sidomma set is a two-knife fishing kit built around matching 6.5-inch fillet knives. Both knives use high-carbon stainless steel blades and plastic handles designed to provide a secure grip. The package also includes two protective sheaths and a pocket sharpener, so you do not need to buy basic storage and edge-maintenance accessories separately.
The unusual part of the design is the number of fishing-specific functions built around the blade. Sidomma adds a serrated area for bait preparation, a raised structure for removing fish scales, and a bottle opener on the blade’s back. These features make the knives more versatile around a tackle box or campsite, although they do not turn a 6.5-inch fillet knife into the ideal tool for every fish size.
Who Should Buy It?
Best For
- Casual anglers who want two compact fillet knives instead of one.
- Freshwater anglers cleaning small to medium fish and preparing bait.
- Buyers who value included sheaths, a sharpener, scaler, and other fishing-oriented extras.
Skip If
- You regularly fillet large salmon, large saltwater fish, or other catches that are easier to process with a longer blade.
- You want a specialized premium fillet knife with several blade-length and flexibility choices.
- You prefer a traditional full-tang wood-handle fillet knife rather than a feature-heavy plastic-handle fishing tool.
Before You Buy: Both knives use the same 6.5-inch blade length. That is a useful all-around size for many common catches, but the set does not give you a longer blade for larger fish. Check the typical size of the fish you clean before choosing this set solely because it includes two knives.
Design and Features of the Sidomma Knife Set
6.5-Inch High-Carbon Stainless Steel Blades
The two knives use 6.5-inch high-carbon stainless steel blades. The product listing also markets them as premium German stainless steel. A 6.5-inch blade gives you a relatively compact working length, which can make it easier to guide the knife around bones and smaller fish than a long fillet blade.
The listing identifies the main blade edge as plain. Separate areas on the back or top of the blade handle other tasks, including scaling and serrated bait cutting. This distinction matters because you still get a conventional cutting edge for normal filleting instead of a fully serrated main edge.
Non-Slip Handle and Control
A wet knife handle can quickly become a safety problem when you are cleaning fish. Sidomma uses a plastic handle with a non-slip grip design, giving you a more secure contact surface when your hands are damp. You should still keep the handle as clean and dry as practical, since no grip design can eliminate slipping completely.
Scaler, Bait Cutter, and Bottle Opener
The back of the knife includes a textured structure designed for removing fish scales. Another serrated section is intended for tasks such as cutting frozen bait and working through tougher material. These features reduce the number of small tools you may need to reach for during routine fishing preparation.
The integrated bottle opener is convenient at a campsite or cleaning station. It should be treated as an opener rather than a general-purpose pry point. Twisting or prying sideways with a knife can put unnecessary stress on the blade and creates an avoidable injury risk.
Protective Sheaths and Pocket Sharpener
Sidomma includes two protective sheaths, one for each knife, plus a pocket sharpener. The sheaths help cover the cutting edges while the knives are stored with fishing gear, while the sharpener gives you a way to maintain the plain cutting edge when it begins to lose bite.
The inclusion of two sheaths matters because loose fillet knives should never be carried unprotected in a tackle bag. Make sure each blade is clean and dry before placing it back into its sheath for longer-term storage.
Pro Tip: After saltwater use, rinse residue from the blade with fresh water, wash it carefully, dry it completely, and only then return it to the sheath. Keeping moisture trapped against any steel blade can shorten its useful life.
Performance and Usability
The strongest usability advantage is not one single feature. It is the combination of two matching knives, compact blades, sheaths, and a sharpener in one package. You can keep one knife with your primary fishing gear and use the second as a backup, or reserve one for fish while keeping the other for bait or food preparation.
At approximately 0.34 kg, or about 12 ounces, for the listed item weight, the set is portable enough for a tackle bag without being a large equipment burden. Because both knives are the same size, however, the second knife gives you redundancy rather than a different blade length.
How It Performs in Real Use
For Freshwater Fish Cleaning
The 6.5-inch length is a practical match for many routine freshwater cleaning jobs where control matters more than maximum reach. The compact blade can be easier to position around ribs and smaller fish than a long blade. Your results will still depend on keeping the cutting edge sharp and using a stable cleaning surface.
For Bait Preparation and Scaling
This is where Sidomma’s extra blade features have the most obvious value. The serrated top section gives you an additional surface for tougher bait-preparation tasks, while the separate scaling structure lets you remove scales without carrying a dedicated scaler for every trip.
For Saltwater Trips
Sidomma lists the knives for freshwater and saltwater use. The stainless steel construction makes that use practical, but salt residue should not be left on the blade. Wash and thoroughly dry the knives after a saltwater trip before long-term storage.
For Camping and Tackle-Bag Storage
The protective sheaths are particularly useful when you carry the set with hooks, pliers, line cutters, and other fishing gear. The pocket sharpener also means you can perform basic edge maintenance without packing a larger sharpening system. The bottle opener adds another small convenience around camp.
How to Use and Care for the Knives
Start with a stable cutting board or fish-cleaning surface. Keep your free hand clear of the cutting path, work away from your body when practical, and avoid forcing the blade through bones or material that is beyond the knife’s intended use.
After cleaning fish, wash the blade carefully rather than allowing residue to dry on it. The product is identified as not dishwasher safe in available listing data, so hand washing is the safer care method. Dry both the blade and handle immediately, especially before storing the knife in its sheath.
Use the supplied sharpener only as intended. The listing confirms that a pocket knife sharpener is included but does not provide enough detail to assume that every sharpening slot or surface is suitable for every type of knife. Follow the sharpener’s supplied instructions and concentrate maintenance on the plain cutting edge rather than the scaler or other specialty features.
Materials and Safety Notes
The blades are listed as high-carbon stainless steel, while the handles are plastic. Because these knives are intended for food and fish preparation, wash them before first use and clean them thoroughly after each session. Avoid storing food residue, salt, or moisture against the blade.
Keep both knives sheathed and out of children’s reach when they are not being used. A non-slip handle can improve grip, but it does not make a sharp fillet knife safe to use carelessly. Inspect the knife and sheath for damage before use, and stop using a knife if the blade, handle, or protective sheath becomes damaged.
Customer Feedback and Ranking
The Sidomma set currently carries a 4.5 out of 5-star rating and has accumulated more than 1,000 customer reviews. That level of feedback gives you considerably more buyer history to examine than a newly launched knife with only a small number of ratings.
Amazon currently places the product at #11 in Fishing Filet & Bait Knives. Ratings, review counts, and category rankings change over time, so you should treat those numbers as a current snapshot rather than a permanent product specification.
Buyer feedback is not completely uniform. The overall rating is strong, but individual experiences with sharpness and edge performance can differ. The included sharpener helps with routine maintenance, but buyers who prioritize premium edge retention or highly controlled blade flexibility may still prefer a more specialized knife.
Pros and Cons
Pros
- You get two matching 6.5-inch high-carbon stainless steel knives.
- Two protective sheaths and a pocket sharpener are included.
- Non-slip handle design helps you maintain a more secure grip.
- Built-in scaler, serrated bait-cutting area, and bottle opener add fishing-specific utility.
- The compact set is suitable for both freshwater and saltwater fishing according to the listing.
Cons
- Both knives are 6.5 inches, so the set gives you no longer blade option for larger fish.
- The extra scaler and opener functions may be unnecessary if you already carry dedicated fishing tools.
- Buyer experiences with sharpness and edge performance are not completely consistent.
Is It Worth the Price?
The Sidomma set makes the strongest value case when you want an all-in-one, budget-oriented fishing knife kit rather than a single specialized premium blade. Two knives, two sheaths, a sharpener, and the extra fishing functions mean you receive several pieces of gear in one package.
You get the most value if you will actually use the second knife, protective sheaths, scaler, and sharpener. If your priority is one highly flexible blade for large fish, several blade-size options, or more specialized construction, spending more on a dedicated fillet knife may make better sense.
How It Compares to Alternatives
The KastKing Speed Demon Pro Fillet Knife is worth comparing if blade-size choice matters more than getting two knives in one set. KastKing offers several blade lengths, including 6-, 7-, and 9-inch fillet options, which gives you more room to match the blade to the fish you normally clean.
The Rapala Fish ‘n Fillet is another alternative if you prefer a traditional progressively tapered, flexible full-tang blade with a birch handle and multiple available lengths. The Sidomma makes more sense when you care about getting two compact knives plus sheaths, a sharpener, scaler, bait-cutting feature, and bottle opener together.
Frequently Asked Questions
What comes with the Sidomma 2-piece fillet knife set?
The package includes two 6.5-inch fishing fillet knives, two protective sheaths, one pocket knife sharpener, and a gift box. Both knives use the same blade length.
Are the Sidomma knives dishwasher safe?
Available product data identifies the knives as not dishwasher safe. Hand wash them carefully and dry them promptly, especially after exposure to saltwater.
Can you use the knives for both freshwater and saltwater fishing?
Yes. Sidomma lists the 6.5-inch knives for freshwater and saltwater use. After saltwater exposure, wash away salt residue and dry the blades fully before placing them back in their sheaths.
Does the knife have a serrated cutting edge?
The main cutting edge is listed as plain. Separate serrated and textured areas on the back or top of the blade are designed for tasks such as bait preparation and removing fish scales.
Is a 6.5-inch fillet knife large enough for every fish?
No single blade length is ideal for every catch. The 6.5-inch size is manageable for many small and medium fish, but anglers who routinely clean large fish may prefer a 7.5- or 9-inch fillet knife for additional reach.
Can the included sharpener be used with other knives?
The listing confirms that a pocket sharpener is included but does not clearly state universal knife compatibility. Follow the sharpener’s instructions and use it only with blade types that its sharpening surfaces are designed to handle.
What is the warranty on the Sidomma fillet knife set?
The current Amazon product information lists a manufacturer warranty of two years. Check the current seller and manufacturer terms before purchase because warranty procedures and eligibility can depend on where and how the product is purchased.
Who should skip the Sidomma set?
You may want another option if you regularly process large fish, need several blade lengths, or want a premium specialist fillet knife rather than a two-piece utility set. Buyers who already carry separate scalers, sharpeners, and bait knives may also get less benefit from the built-in extras.
The Bottom Line
The Sidomma 2 pcs Fishing Fillet Knife Set is a recommended-with-caveats choice for anglers who want two compact 6.5-inch high-carbon stainless steel knives, protective sheaths, a sharpener, and useful fishing-specific features in one package. Its biggest strength is the amount of practical gear included, while its main limitation is that both knives use the same 6.5-inch blade length, which may be less convenient for regularly processing large fish.
