This is a well timed commentOf course there is, I've had at least a dozen different folders that were absolutely perfect. But they were all different and at different times in my life when my life style had changed. It all depends on what stage of life you are in.
When I was a young troopie in my 20's and serving in the army, the perfect folder was different than in my 30's in the civilian world, where I was driving a mini van and being a budding soccer dad and Boy Scout dad. In my 40's the perfect folder changed again, the kids were older, more independent and life was a little less hectic. In my 50's it changed again, and in my 60's it was a bit different. My dad was right, it all depends on who you are, what you're doing, and where you're doing it. My perfect folder has went from a Buck 301 stockman teamed up with a medium SAK, to a Buck 303 stockman still teamed up with a SAK. to a Case peanut and smaller SAK, to a small SAK in my senior years. Things change. Needs change.
My neighbor who I believe just turned 60 a little while ago bought himself a swiss army and a classic, we met in the mailroom today and he used some smaller kershaw knife to open the package and then closed up the knife and tossed it in the trash, then proceeded to pocket the swiss army knives. He saw me confused but knew why and said " my grand kid has been bugging me forever to start carrying a bigger locking knife, said it was safer and better, I finally got one so he'd quit being sore, but these damn things are so blocky in my pants and aren't so sharp, I grew up on slipjoints and never had cause to change, even when these young'n knives came about everywhere. Anyway I tried it but can't do it, so here I am. Better this way"
Then walked off.
I stood there for 5 minutes taking it all in.
As per the thread question, the perfect knife to me is a knife with the most multi purpose and utility value.
Spear or drop point folding
