Buyer Guide for Best Salmon Fillet Knife

A good filleting knife requires to have some specific characteristics to be effective for the job. Before making a purchase decision, here are a few things that you should consider.

1. Design of the Handle

This is one of the most important features that will determine your effectiveness while cutting your salmon. Knives come with different handles such as wooden and rubber handles.

Wooden handles are good and provide a good grip. However, they are not reliable when you’re working in wet conditions compared to rubber handles. Additionally, some knives provide you with a guard that prevents you from cutting yourself.

 You should find out if a knife has good safety features and a non-slip handle.

2. Blade Strength and Quality

The blade is the primary part used in the cutting and filleting fish. Therefore, it’s important to ensure that you purchase a high-quality knife with strong blades. A low-quality blade will not be effective while doing heavy-duty work and is prone to get destroyed.

Additionally, a good blade should be sharp enough to cut through the salmon without force or much pressure to avoid the possibility of accidents.

 In our opinion, carbon steel blades are slightly stronger than stainless steel blades.

3. Manual or Electric Powered

We have three types of fillet knives based on the source of power used to operate them. Manual knives are operated by using hands while corded and battery-powered knives use electric power.

For heavy-duty use especially for industrial use, battery-powered fillet knives are important since they ensure you work faster. However, if you’re buying it for home use, a manual knife is enough although it requires more power to use hence causing fatigue easily.

Corded knives on the other hand are more powerful but the wires limit your chances of working away from the socket.

4. Blade Size

Fillet knives come in different sizes depending on the preference of the user. Depending on the size of the Salmon you’re filleting, the blade should either be long or short to ensure you’re comfortable while working with it.

It’s important to note that long knives are better while cutting and cleaning large fish whereas small-sized knives are good for cutting small fish.

5. Flexibility

A flexible knife is very important while filleting fish because it gives the user the precision needed to make perfect cuts that don’t leave meat on the bones of the salmon. Therefore, the more flexible a knife is, the better it’s able to do a good fish boning job.

Normally, the smaller knives are always more flexible compared to the larger knives. However, the work that the knife shall be subjected to will determine whether it’s flexible or not. This means that you should be able to find a knife that is flexible for your kind of fillet activities.
