KAJNIN, I actually own three MPFs. The Sebenza is an excellent cutter and the MPF is an excellent folding pry bar that can also cut. Fit and finish, the standard Sebenza has an edge over the MPF. Functionally, the MPF is better due to its strength and low corrosion factor.
I liken the Sebenza to a Colt Python and the MPF to a S&W 686. If I was shooting in a competion the Colt will be used, but if I was going into the bush then the S&W will go with me.
