Of the venerable , traditional pocketknife ?
I had three inspirations.
First of course was my Dad.
My Dad is offspring of those generations that bought something and made it last until it broke, usually that is.
I remember being a kid and goin fishing with him , he had two knives which I thought were the best knives in the whole world. First knife is an old filet knife which I still have in my drawer , IIRC it is an old Rapala. The second knife is one he gave me some 15 years ago and I wish near every day I still had it , it was his knife he bought while in the Coast Guard , single blade with rope or marlin spike , those knives go by various names.
I think it was an old Case , it had dark , dark brown scales.... long story short it was 'liberated' when I had a party some years ago , I shouldnt have left it where I did.. oh well.
Second was my Grandpas.
My Grandpa Fries gave me his old Sodbuster , he found it while walking in the nearby park one day , another knife I wish I still had. I do not recall where it is but hopefully someone , somewhere is putting it to good use !
My Grandma Reynolds gave me my Grandpas pocketknife after he passed on ,this knife I still have thankfully.

The blades are all well worn , the honest wear and tear one see's on older user knives. The scales were almost worn off so I replaced them with stag , not the best job in the world but it works , I did this well before the advent of bladeforums and the internet
Last but not least !
One of my earliest knife memories is an old Irish Spring commercial , where a saltyhearty looking Irishman is walking and speaking of the virtues of using Irish spring to keep smelling fine , he used his pocketknife to cut off a sliver of the soap.
It is that commercial which I can still picture in my mind that had led to this fixation for single blade Slipjoints all these years.
I have appreciation for all Slipjoints but nothing else makes me eyes twinkle like a single bladed beauty.
