As an observer I'll comment: maybe you need to relax and you might learn something.
I suppose it does appear hasty, however, THR is infamous for someone asking a question only to have another poster tell them 'No, that's not what you want, *this* is what you want'. When people start off with posts that appear to be in that vein, my patience rapidly disappears.
However, it can be hard to judge intent on the internet, so I'll try to avoid being hasty in such.
My quip that tantos are better than clip points was tongue-in-cheek, as yes, I realize the utility of a tanto style blade is limited at best.
If I wanted something aside from a tanto-style, I'd ask for suggestions towards that end. If there is literally nothing out there that meets what I'm looking for, some indication of that would be useful as well.
My experience compared to the collective experience of the posters found here does pale by comparison though, and I'll readily admit there's heaps I don't know.
If someone wants to say 'The tanto style is a recipe for trouble because of X, Y and Z compared to style X, which deals with those issues.', that's one thing.
In a defensive situation, honestly the only things that appear to matter are:
'it's sharp enough'
'has a good grip area',
and in the case of folders 'the lock won't fail during use'
(note that that's not 'the lock won't fail if you're using the knife as a pry bar').
'The blade comes to a point' is also better than the converse.
And as always, the longer the better within legal bounds.
I suppose you could, worst come to worst, use a ball point pen as a defensive tool, a chair, a pen knife, something with a 1.5" blade, etc. But why do so if you can spend a little time and get the best thing for the job? That said, I'm open to recommendations for 'this is better and this is why it's better!'
