I was looking at reviews for the multitools I had and others I was interested in, and stumbled upon the main site. That led to me deciding to check out the forum section. I lurked for a little while and saw that this was a good forum for me to join. I saw that it was a forum where I could really learn a lot about my growing interest in MTs/SAKs.
I've only joined one other forum before this one (not MT/SAK related), and I saw so many ridiculous and vulgar posts and so much in-fighting that I haven't been back much since. This place appeared friendly and educational, and it has not disappointed. So many other places just seem to have members that enjoy arguing and thinking they're big and know it all about whatever topic is discussed, whereas here, members are happy to help in any way they can and don't try to start arguments or any of that nonsense.
I'm very happy I joined, and I spend a fair amount of my free time here, so much that I've now become a full fledged member of the "No Life Club"
