1. As you are familiar with the Kershaw line, try a plain blade 3655 with a 3.5 inch blade. It will cost you under $25 most places on line.
2. I don't work in a warehouse. before shtf, I prefer a plain blade. Serrated blades get hung up for me.
3. I distinguish before shtf from after shtf. I want more options after shtf.
Have you ever been cut by a serrated blade? I have. Opening a government box. I held up my hand to the doctor and he asked me what to do. I said it serrated and all he could do was clean and bandage. He would not be able to stitch it up. This is why I have two plain edge Spyderco Police models next to the computer and a couple of serrated Police models for shtf. P.S. I had a military instructor who stood to close to the line when people were deploying serrated blades. He still had the scar and mentioned that it could not be sewn up.
