I am in the process of negociating for a new Rat Trap. I have an excess of small EDC fixed blades to trade. For now, my most rugged folder is my Benchmade Skirmish framelock. It's a brute of a folder. Blade is S30V, handle is titanium. Got it on sale from my gun dealer. I haven't used it yet. Here it is next to my YK. The Skirmish is heavier!

It's bulky and a bit heavy for the pocket. I may remove the clip and carry it in some sort of belt sheath. It makes the Dejavoo look like a gentleman's knife!

I doubt if even the Rat Trap will be more rugged. Look at the lock on this brute compared to the Dejavoo.
