Hello people, i have many home self-defense type weapon, but I am interested in getting a Machete. This Machete would be used for chopping wood and such, and will definetly be used as a secondary home defense weapon. The Machete's i'm interested in are these, the ontario standard issue military machete, w/18inch blade, with no saw, or a 22inch blade Blackie Collins heavy duty machete, also made bye ontario. This one has that knuckle guard, tell me, which do you think is better, is the extra heft of the 22 inch blade better, or the versatality of the 18inch better. And also, how do these machetes come to you, are they all rusted up, gunky, dull as hell, do they have a point, overall how good are they. Oh yea, i'm gonna spend no more than $30 beans for this, i have a place where i can get either one for under $20, and a collins sheath for about $10 bucks, so don't recommend a $300 dollar machete, thanks.
