If there is one thing I had learnt about pocket carry or key attachments,
Is that such a loose carry or dangler had better have a simple protective sheath or cover.
Better for both the tool and pocket wear.
I don't know about the US, but it is still available in The Netherlands. (and I think other European countries) https://www.knivesandtools.nl/nl/pt/-victorinox-bantam-silver.htm
To me the Bantam is borderline keychain worthy due to size. They say you shouldn't have too much weight hanging there when the keys are in the ignition. Don't really know... I tried a Vic classic (alox) for this and gave it to my wife for her use. I have a Leatherman Ps4 Squirt on each of my car key chains which I know is heavier than a Bantam. I usually keep my car keys in my pocket while at home. I have two sets of keys in my pocket; house and other, and car/truck. The Bantam is the knife I carry with a larger slip joint so I have the full sized tooth pick and tweezers. Both are useful at times. Just bought a small Tinker model which is 3" closed. I wouldn't put it on a keychain myself.
Well the Bantam doesn't have a key ring, so that's not an option. Weight wise, it wouldn't be a problem to carry on the key chain. It weighs next to nothing. Length wise I think it doesn't work.To me the Bantam is borderline keychain worthy due to size. They say you shouldn't have too much weight hanging there when the keys are in the ignition.
