Pictured here is the Pacific Salt Black Blade from Spyderco. It's the latest to join their Salt family, and I must say I am a big fan of the line. Mr. Merwin even brought it up in a post not too long ago, and Tim Romano from the Fly Talk blog chimed in, also voicing his love of the Salts. There's really no big secret to why they're great fishing knives: They stay razor sharp and won't rust. I mean throw one in the ocean, pick it up a year later, and it'll be clean.
