Victorinox Tinker Deluxe

So I bought myself a Victorinox Tinker Deluxe SAK, after my friend told me he's been using his SAK for the last 15 years. I'm into small tinkering work, urban partisan activity and like to be prepared.

I'm not sure if it's gonna be a life-long purchase, but from what I've seen, it's quite durable. Will need maintenance and correct usage, though.
