Hi, i'm new to this forum and I wanted to know your opinion on this matter. Recently i bought an automatic knife, very cheap (made in China), to use as a EDC knife as a keychain. It looks like this one:
It have ~6cm of blade and ~14cm total. I love automatics, that's why i got it.
But, i was thinking that maybe a knife with more tool would be better like this one:
Essential to me are the scissor, saw, bottle and can opener, and of course, the blade. This one have almost the same size as my auto, but it's a lot heavier due to all the tools. This one also looks like cheap made in chian knife.
So my questions are:
1- Which do you prefer (auto or swiss) and why?
2- There is much difference from a cheap knife to a original one (victorinox or smith & wesson)?
3- What's the size of your EDC knife?
As i said, i'm looking for a knife to use as keychain, so i don't want a big blade, something between 6-9cm would be nice. Also, in my country it's hard to find good branded knives, they are rare and expensive.
PS: sorry for my bad english.
