I have been freediving the north california and oregon coast for the past 6 years and shortly after begining to dive here I realized that a knife was more of a snag hazard than it was worth... so i quit carying it. I have a renewed intrest in carying a knife while freediving to dispach bigger fish than I have been spearing. where do you guys keep your knife to keep it from snagging when you are swimming through thick kelp? Also what is a good low profile knife for freediving?
