I recently used the Problue KN-79 Spear Fishing Knife for a deep-sea fishing trip, and I must say it exceeded my expectations. The compact size and quick-release button made it easy for me to operate with one hand while holding onto the fishing rod.
Lester Goh –
I’m not sure I agree with the ‘unbeatable in sharpness and strength’ claim. After using it for a few trips, I’ve noticed the blade starts to show signs of wear and tear. Still a solid knife, but not quite as impressive as I thought it would be.
Celine Ho –

I’m considering purchasing the Problue Spear Fishing Knife for my next trip, but I have some questions: Does it come with a lifetime warranty? Is the 420 J2 stainless steel blade resistant to corrosion? Can you use it for both saltwater and freshwater fishing?
