I own many Gerber knives and all are top notch quality but this particular "fillet" knife is literally the workhorse of my kitchen. I slice meats paper thin. I can cut right through bone. It goes through raw potatoes like butter. The sharpener that is built into the sheath works well enough to put a new blade on the knife if it ever gets dull but I like a good blade on my knives so I use an old school sharpening stone on most of my good knives.
I buy boneless skinless chicken breast in bulk and freeze the cutlets but before freezing, I spend an hour cleaning them up real nice, removing any fat or junk left over from the butcher. To make my work easier, I put this knife through the sharpener a few times and start trimming. It makes the work so much easier compared to my other "regular" knives. It goes through chicken like nothing is there.
To use this knife for "just fishing" is a waste in my opinion. Most old junk knives will fillet a fish. I do own 7 of these knives now and I do keep one in my tackle box but I don't want to ruin it so I usually use my cheapie fillet knife while out at the beach or dock to do the dirty work. At home on a cutting board it makes very easy work out of filleting fish. I do use one of my older knives to cut up frozen squid for bait. The knife cuts right through the block of frozen squid like its nothing.
The knife has just enough flex to it to make it useful for many items but is rigid enough not to slip or break when cutting. The handle is a very grippy type of rubber. It's got a real nice feel in the hand and it will not slip.
As I said, I own 7 of these knives so I guess you can say I love them. I also bought one for my ex-wife as well as my parents and they too love the knife.
