The fact that it comes with four different blades and a case makes it a versatile tool for various filleting tasks. However, it is important to note that this knife is relatively heavy at 1.11 pounds, which might be a drawback for those looking for a lightweight option. Also, since it is available as a corded and battery-powered option, users need to ensure the battery is charged for cordless use, which could be a minor inconvenience.

The additional LED light feature is a thoughtful touch for those who may need to work in low-light conditions. However, the knife's weight at 3.81 pounds could be a bit cumbersome for prolonged use.

At 3.16 pounds, it may be slightly heavier than some users prefer, especially if used for prolonged periods.
