## Questions & Answers

**Q: I am looking at a manual sharpener what would you  recommend?**
A: Get yourself a Worksharp knife sharpener, either the orig one for $60, or the updated Ken Onion edition ($120), both are FANTASTIC.  I’m TERRIBLE at sharpening anything, but this thing (I got the Ken Onion edition) has made it easy, quick and best of all, a “good knife sharpener” out of me!  I don’t sell them, have no affiliation...    I just like a good product when I get one, which is rare these days.  Good luck.

**Q: How well does this hold a edge? Also after a couple sharpening does it still hold a edge like if it was new?**
A: For those too young to remember great grandpa shaving with a straight razor, let me give you a quick education. RAZOR sharp knife means it will not hold an edge.  The sharper the edge, the quicker it will dull. That's why great grandpa had a razor strop that he honed his beard cutting steel with every time he used it.  A fine razor edge on a fillet knife is important, as is the knowledge that you must hone (not sharpen) the edge regularly to maintain it.

**Q: Can a lefty use this knife or is the blade made for right handers?**
A: I am also a lefty. It works well. Really solid knife for larger fish.

**Q: What would be the best sharpening tool for this knife?**
A: This is a large can of worms on this ask; I ask 10 folks, will get 10 answers.  Since I was little, was taught to use an Arkansas stone, it's my comfort zone and haven't met a blade I couldn't hone yet.  I've tried other methods, but for me, the stone is far superior.  Technique and angle are critical no matter what your chosen poison for sharpening, practice, practice, practice.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great knife for the price
*by J***J on May 15, 2025*

I picked up this KastKing fillet knife for weekend fishing trips, and it’s been awesome so far. The blade is super sharp and flexible, which makes filleting really easy. It’s a good size—big enough to handle decent-sized fish, but not bulky.The build quality is solid. It feels well-made and not cheap at all. The handle has a nice grip, and the knife has a good weight to it—light enough to handle easily, but heavy enough to feel sturdy.The lock mechanism on the sheath is a nice touch. It clicks in securely so I don’t have to worry about it coming loose in my gear bag. Definitely a thoughtful design.For the price, this knife is a great value. It feels like something that should cost more. I actually ended up buying another one as a gift for a buddy who fishes, and he was really happy with it too. Would definitely recommend for anyone looking for a quality fillet knife without spending a ton.

### ⭐⭐⭐⭐⭐ Good and sharp
*by D***L on May 15, 2025*

Good sharp quality knife, easily bend to a desire and the handle is great too. Although the size got me confuse, it's the length of blade only, not the whole thing.

### ⭐⭐⭐⭐⭐ Probably going to be buried with it.
*by I***A on April 20, 2025*

I've fallen in love with this maker. I've built a small collection with this one as one of my favorites. It is razor sharp and nicely flexible. It is strong and has a good size, well made handle.Down side: you'll probably gain weight from wanting to use this knife every night to cut up then consume some good meat. Pro tip: get a sous vide machine.
