a lockback is usually the last choice in a combat knife for those reasons. A linerlock is preferable to a lockback, but the best choice for H2H, is a framelock.
Uhh, you may want to think about that one again. I'm always surprised how people can post so matter of fact about something that they really don't know about. Lockbacks are many times used for MBC situations, they are strong and reliable, they just arent the newest lock design out there. They are time tested.
There are many people on these forums that do not trust liner locks for normal use, and especially not in a combat situation. There are people here with permanent nerve damage due to poor liner locks. If there was one lock type I would personally not want to use in a hard use situation, its a liner lock. Not all are bad, but thereve been too many bad apples out there. They are weak to being torqued, which is something Id want to be confident in, if it were my only knife.
Spyderco makes some of if not the best lockbacks out there. Depending on the model, some are rated for MBC, which means they are meant to handle knife fighting. The Native of course is not, it is FRN. The advantage to this is less weight. When wearing a duty belt and all your gear, it all adds up.
About the subject, either the Grip or Native would be a good choice. I think the ergos on the Native are better, plus you get s30v that is better than the standard Grip steel. With gloves the round opening hole tends to be easier for the majority. Neither one should have problems with accidental closure, but they are folders, all folders can fail.
I'm with the people who suggested you just get one folder instead of two. This way you have only one knife to remember how to use in an emergency situation. Since the Grip and the Native are on the lower end of both knife companies, you may want to put the funds into a higher priced model. I would highly recommend the Spyderco Lil' Temperance. This was made as a tank and is MBC rated. The handle ergos are made to give a strong secure grip. The enlarged hole is great for situations where you are wearing a glove. This model was recently discontinued, but you may still be able to snatch one up. The Lil Temp sounds to me to be the perfect knife for you. If not you can go with the Manix or Mini Manix, IIRC both are MBC rated. The Paramilitary is another strong choice.
