For what it's worth, I ordered two more Tuff Lite knives. After a couple of days using them, I am very pleased with the design and effectiveness. They are great pocket knives.
They glide through cardboard.
They are small enough to drop in your pocket.
They are inexpensive enough for me to buy several for my crew to use to box and ship.
They are quite robust, and brightly colored.
The blade is a great wood whittler.
The ergonomics are quite good, and fill my XL hand.
One handed opening.
Takes to stripping quite well, making edge maintenence easy.
