I'm currently looking for a hard use folder. In the process I've view a bunch of videos, and looked through broken knievs threads to see what is listed and how the broke. I've also look through various govenrment test, manufacture test, etc.
I've see far more Spydies broken than Benchmades. A few the manufacture fessed up to manufacturing issues, the Bushcrafter is an example. They redesigned it to try to keep them from breaking. I had a few Spydies on my list until I did the research, now not so much. Too bad, I was just getting over their reputation from when they first came out. Such is life.
If you're never going to use the blade hard, or do more then open packages, mail, or other normal knife things then either would be great. I still might pick up a spyder to fill that roll, but I'll want a back up on or need by when I do.
So far only two folding blades have made it though the test of things I might need to do with a blade, and to be perfectly honest about it Benchmade isn't one of them either.

Folders are just never going to hold up to the things some need to do with blades and that's why we still have fixed blades for many task.
If a spyder craws on market that does 90% of what I want my knives to do I will be all over it like a can of Raid. I'm warming up the the impratical blade designs...A little.
