Well its going to do light bushcrafting and my military everyday needs which can be strenuous at times. To be honest lateral strength really doesn't have to play a major part. Just a strong design not going to lose the tip. And m4 is to corrosive i don't want to depend on coatings I'm in Washington by Seattle it's wet 8 months. I like the reverse tanto blade on the 810 just not the m4 steel. The 940 is to small in hand i got one and I'm getting rid of it it's annoying closing and opening it i don't need axis lock on a tiny knife. Plus I'm pretty sure i got one someone else returned the clip was already warn out so that was lame.
