Well to decide this I had to do some thinking. Only five- Ok so sentimental, looks, utility, dress, self defense, outdoors.... all have to be covered. Went to the knife drawers and worked down the list a bit to:
Closeup of them:
Narrowed down to the winners:
CRKT Crawford Kasper Folding fighter- bigger fighter- self defense and big hard work duties- AUS 6 most likely, partly serrated. Great retention, oh- and the first knife my now wife ever bought me!!
Elishewitz custom folder- the ultimate in modern materials- Damasteel, Blue/black carbon fiber, white micarta, black g10, titanium liners. Solid lockup, a custom make, and feels great in hand.
Boye Dendritic Cobalt folder with marlinspike. Non magnetic blade, very soft RC30's I believe, titanium marlinspike. Awesome for cardboard, plastic work, the marlinspike removes all kinds of staples and light nails. great all around, I've used it for years in a warehouse. Birthday present for me from me and the wife.
Kershaw red handled Composite Leek: Speed safe, composite CPM D2 blade with a hybridized red smoke handle (looks too plain with the regular silver handle). My favorite color is red so it had to be represented. Great slim slicer in all metal.
Case Damascus Stockman. Damascus blade with burnt bone scales. thin blades take a good edge- looks very sharp. Slipjoint for those people uncomfortable with a pocket clip. Fit and finish are not the best but it does look great!
Special mention to my Moon Song Sebenza that I bought in memory of my Mom.
5 Isn't enough.
