VG-10 is one of the more rust resistant stainless steels while, unless you want to be an idiot and leave your knife in a jar of battery acid overnight, H-1 is corrosion proof. Serrated H-1 also holds an edge better than serrated VG-10. The Pacific Salt uses an unlined FRN handle, so it will be lighter than an FRN Endura, which has nested stainless steel liners. Lock strength should be virtually identical, since both use 3mm blade stock. The Endura can be set up for tip up or tip down carry, Pac Salt only allows for tip up carry. As for modding the tip, you would not be the first to do it. Straight out of the box, no knife can fit everyone's lifestyle perfectly. It comes down to which characteristics are important to you.
