Excellent boat knife and for diving, impervious (so far) to salt water. Well thought out functional design. Have had it now about a year. I really like the chisel edge point, excellent for prying mussels off rocks etc. Sheath is lousy, broke easy and unreliable. Wonderful folks at Puma USA would have replaced it, I chose to purchase a leather one they chose that fit it. Works perfectly, I wash, let dry and re-oil after getting wet. Wear it diving or tied to Zodiac for crabbing, bait cutting etc. Not too thick a blade, plenty strong. Beat it up instead of my Chris Reeves...... which would rust......
