Okay, my
YOUNG friends...forget the slipjoints and stuff that reminds him of how old he is. We already know exactly how old we are, and we are
tired of being reminded by our daily intake of prescription meds, our sore hips and shoulders, and our lack of Vim and Vigor. And, my OP friend, you don't apparently know anything about his history...perhaps he served in Korea or Vietnam while you were in swaddling clothes. Do NOT assume.
I'm a few yrs behind him; I remember my old Buck, Case, Barlow, etc. and I am happy they are gone. Nothing is sweeter than the smooth sniiick of one of my three CRK's or the compression lock on my PM2's. I've had about nine PM2's recently, in various super-steels, and love 'em.
Give him what he REALLY desires: a taste of youth. A used Sebbie or Umnumzaan, a Strider SJ75 would be nice. There is nothing offensive about a few battle scars on titanium slabs. Your uncle has a few scars also. Or, if you want newer and cheaper, a Titanium Lum Chinese (VG-10) for about $160, a Sage 2 in titanium ($150) or a blue PM2 in M390 (they go here for $230-$250) would be right
"up his alley." Yes, we old guys even used to bowl...

We may not use SmartPhones, but we do enjoy modern folders that are slim, a blade of 3"-3 1/2", max weight of about five ounces, titanium or carbon fiber, and a nice pocket clip.
Honest Injun! Pun intended and apologies to any who might be offended by that common remark from my youth.
