If it is only an occasional quick tool to do something they indeed basically last forever. I think I had mine for 25 years or so now. Mostly switched to a Leatherman though as the pliers in those are often very helpful.

PSA: I've been IDCing these (i prefer supertinkerer or climber 92? mm models) my entire life and I have actually broke one! When you inevitably break the spring on the scissors (somehow I use them the most), don't compensate with your thumb pressurering against the hinge. Have it replaced, many shops do it for free. Or in several years - you will break the scissors off just below the hinge. Didn't know/expect that was possible. If something I am below average strength. Still the best knife I know, own 1/2 a dozen, even though I confess muscle memory probably plays a big role.

@chaos_rat, I've had and used the same one daily for ±30 yrs. I bought a leather belt holder with it, which included a small sharpening rod. The plastic shell is broken in a few spots from occasional drops over the years. Also a shot is worn in it's shell from rubbing against the button fastener of the sheath for all those years. I lost the toothpick many years ago. I purchased a new one in 2020, but have yet to open it's packaging. I just have too much history with the old one. It's a good buy. You won't regret it!

I've carried a version of the Classic SD for over 30 years. It originally as a promotion from Marlboro cigarettes with a chain to connect it to your key ring. It gets lots of use.

When my son was young he got used to me always having it and would always ask to use it. Now he carries his own.
