Heres some of the things I have used my Penknife khuk by HI...
Chopping upto 7" saplings down into foot lengths
Splitting saplings for fire wood
Used inner curve to peel bark
Skinned and cleaned fish with tip
Cut everything from beef to chicken, onions, tomatoes etc
Dug up underwater roots
Cut cordage
Cut leather
Hammered in small nails hundreds of times
Trimmed and cleaned nails
Used as a coat hook in dead trees
Cleared bush and trimmed natural shelter materials
Scraped fire wood to dry stuff
made fuzz sticks
Took a chunk out of my left knee and moleskins
Checked the blood colour in my thumb knuckles
Burnished wooden dowels for multiple purposes
Battoned through logs up to 13 inches doing one half at a time, did result in cracking a hole into the buffalo though, it's now leather knot wrapped...
Cut and trim leather often.
Lifting and holding up a fridge to remove dead mouse.
I think it's my favourite knife of all time.
Only one thing, fish guts tend to make the grip a little slippy unless you mod it.
