Good to see I'm not alone. I tend towards larger folding knives. The favorite is my Spyderco Military Carbon Fiber with BG-42 steel blade. It was a sprint run so only X amount were made, though I can't recall the number. It's big, and the sheeple types get nervous around it, but the CF construction keeps if very light for it's size and I've never regretted having too much blade as opposed to too little. It's an expensive knife though so I'll often carry a Spyderco Endura 4. Still a good size knife but not quite as big and lots cheaper.
If I'm really worried about losing something (cargo pocket of swim trunks, etc) I've got a little Gerber folder.
