Which of these folders would make the best self defense back up to a ccw? The Endura would open the fastest(if you use the wave)but the lock might not be as strong as the Recon or 710. The Endura also is kind of a light weight to medium folder not as strong overall as the other two? The Recon would have the strongest lock of the three but it does not have the detent like the Endura does. It opens slower than the other two as well. The handle on the Recon feels like it was made for my hand. The choil would keep your hand from slipping on to the blade during thrust cutting. The 710's lock is fast and smooth and very quick to open also very strong. The handle is slippery and does not have the best guard but it is very thin which is nice for carry. The steel offered on all of the models is not a huge concern because I have other knives for utility. Which knife do you think would serve this purpose best and what other pros/cons do you think one model offers over the other for this role? Thanks
