This is not my oldest knife, but it is the one that I have carried and used the most in my life until it was retired (from carrying) in 2009. I originally got my CS Tanto from a cutlery shop in a local mall back in 1984, some 29 years ago. I had to put it on layaway and pay for it over 1/2 the summer as my wife wouldn't let me pay for it outright with (our) money as she thought it was too expensive.. So I had to cut back on some beer and fun for a couple of months. Boy was it worth it.
A couple weeks after getting it, I noticed the gorgeous Kydex sheath (in my pics, but did not come with my Tanto) was on display at the cutlery shop with no knife in or around it. I asked the manager if it was for sale, and he said "No, it's a dealer's sample and not for sale." or some such thing. Well, I wanted it, and after several trips back to the store, badgering him on how much I spent there, good customer, yada, yada, he finally sold it to me for $25.00. It seemed like a great deal at the time as my knife didn't come with a sheath originally.
After that, my Tanto was on my belt or in my carry pack on every family or individual camping trip, hunting or fishing trip, 3 or 4 wheeling trips, and anything in the back woods or outdoor type adventures. It has been the most faithful, sharp and useful knife I've ever owned to date. It has been used for things I can't even remember (nothing bad mind you) and has never let me down. I carried it faithfully for 25 years and a couple hundred trips of all sorts, until late 2009 when I was just getting ready for a short outdoor getaway, and the belt loop securing plastic gizmo on the sheath just cracked open and the loop holder became detached. (see the pic below)
Anyway, my Tanto with the busted sheath will still be in a pack or luggage, but unfortunately it's been replaced on my belt by another knife until I find a way to repair or replace the kydex sheath.
That's my story, experience, and here are some pics..... Thanks, Mark.....
Here is sheath busted in 2009 after 25 years of use! Still functional, just can't mount on a belt.
