Why are the serrations a must? (Just asking no sarcasm)
Outside of opening letters and boxes, the next most common use for my carry knife for is cutting rope, paracord and zip ties. I have a lot of stuff like that around my house especially hay rope. I or I should say my wife and daughters have horses and the kids love using the hay rope to make forts, traps, tie random stuff together and leave it in the yard for me to run over with the mower.
My son likes serrations because they look cool.
I've looked and couldn't find one with serrations so I made an offer on that scarab, we'll see how that goes.
