A couple of years, I saw a small wide folding knife which locked open that clipped to the backpack strap or an outdoor vest. It wasn't the Buck knife. I thought it may have been CRKT or a maker that specialized in knifes for outdoor activities Any suggestions for a similar knife.
Are you looking for a knife with a built in carabiner? Something like the Kershaw Funxion or Leatherman Crater?
Check out the Spyderco Snap-It, was out of production for a while, but they brought it back for 2016.
Kershaw 1004 Carabiner, Boker Plus CLB Karambit or the DPX HIT Carabiner may be worth looking at also.
Sanrenmu 7033, 7048, 7053 and 4077, depending what size you want.They're all well below $10 so no big deal if you lose one during hiking...
No big deal in $; but perhaps a big deal for the OP if he's out in the middle of nowhere without the blade he thought he had? Just sayin' .... L'chaim! Moshe ben David
True Utility in the UK has the knife I was looking for but it appears the locking feature has been removed from some of the knifes.
That is a good feature I agree. But also depends on how far you've traveled since knife fell. I'm not talking about dropping when it is in your hand... I'm considering if for some reason (e.g., Professor Murphy's Law of the Universe!), it somehow fell out of a pouch, pocket or whatever without being noticed. Which could happen I think if someone were pulling something else out of the same pocket without stopping to take the pack off; e.g. a map from a map pouch; a water bottle; etc etc.... L'chaim!
