One reason I'm a huge fan of the Classic and the MiniChamp is that the tiny scissors are so handy, and work so well. I always have one on my keychain. I also just ordered a Climber, so I'll see how I like the scissors in that size of a knife. The Super Tinker might have been better due to the phillips head, but (a) I wanted Silver Tech and (b) found a good deal on the Climber.
One of these days, especially if I stumble upon the right eBay deal or Amazon sale, I'll get a SwissChamp or other large SAK just for the pride of ownership more than anything. But I may carry it in my workbag and use it more than I think I will.
Awesome.
Hey ever tried using a Rambler? It's a size between the Minichamp and the Classic. I has all the tools of the Classic plus the phillips screwdriver/bottle opener tool. It might be a good fit for your keys, lightweight but has the functions that you mentioned.
Yeah those tiny scissors are great. And if you love those, I'm pretty sure you'll love the ones on the Climber.
I chose the Super Tinker over the Climber because I don't usually drink wine. And even if I do, I usually drink white wine so not a lot of cork there... just those things that pop. Also I don't wear eyeglasses so the tiny screwdriver might not be used as much too (however, I've used the one on my SwissChamp a few times on certain other screws so I know it's also good). But yeah, that corkscrew is very useful too. I've untied a lot of stubborn knots using that so the Climber is an awesome package.
As for the Silver Tech, I have to agree, I understand it's appeal. It's very... well... techy.

Like a tiny Millennium Falcon.

hehe. However, I heard that translucent scales scratch easily so I'm worried about that. And that it might be easier to crack than the typical cellidor. The ones from my Super Tinker cracked with just one fall on the floor. But since then, I've replaced the scales with hand-carved wooden scales.

Now I don't have to worry about my keys scratching my scales.

But yeah, I'm sure you'll love your Silver Tech. Tell us about it when you get it.
As for the larger SAK's, a SwissChamp is always a win. But I also want to get a Forester.

Those bigger saws are really good.
Cheers.
